  2. Basic parts of most all plants are roots, stems, leaves, flowers, fruits, and seeds.

    roots help provide support by anchoring the plant and absorbing water and nutrients needed for growth. They can also store sugars and carbohydrates that the plant uses to carry out other functions. Plants can have either a taproot system (such as carrots) or a fibrous root system (such as turf grass). In both cases, the roots are what carries the water and nutrients needed for plants to grow.

    Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells. They move water. The phloem cells move the food. Stems also provide support for the plant allowing the leaves to reach the sunlight that they need to produce food. Where the leaves join the stem is called the node. The space between the leaves and the stem is called the internode. You'll find out why this is so important as the mystery develops.

    Flowers not only look pretty but, in fact, are important in making seeds. Flowers have some basic parts. The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules.

    The fruit is the ripened ovary of a plant containing the seeds. After fertilization, the ovary swells and becomes either fleshy or hard and dry to protect the developing seeds. Many fruits help seeds spread (maple seeds). Many things we call vegetables are really fruits such as tomatoes, cucumbers, and beans.

    *Sepals:Protect the unopened flower.
    *Petals:May be brightly coloured to attract insects.
    *Stamens:The male parts of the flower (each consists of an anther held up on a filament).
    *Anthers Produce male sex cells (pollen grains).
    *Stigma:The top of the female part of the flower which collects pollen grains.
    *Ovary: Produces the female sex cells (contained in the ovules).
    *Nectary:Produce a sugary solution called nectar, which attracts insects.

  4. 1. Roots
    They are an essential part of the plant's survival, tasked with the responsibility of anchoring the plant to the ground and also seeking out moisture and nutrients to be delivered to the plant and enable it to grow.

    2. Stems
    its main function is to carry moisture and nutrients from the roots to the rest of the plant. There are different types of cells within the stem that perform their own functions.

    3. Leaves
    are where photosynthesis occurs, transforming the water and minerals that the roots have collected and that the stems have distributed and turning them into glucose which is food and energy for the plant. For photosynthesis to take place, the leaves make use of sunlight, carbon dioxide, water, and chlorophyll. Most leaves tend to be green, thanks to the presence of chlorophyll.

    4. Flower
    The bright and beautiful part of the plant which you see is the flower. They play a role in making food. A flower has female as well as male parts.

    The function of the flower:
    It is the reproductive organ of plants, it has its origin in flower buds. Its function is to make seeds and it is made up of a male part called stamen and a female part made of pistil.
    4.The fruit
    The function of the fruit:

    They are of various sizes, in relation to the seeds they present.
    Leaves
    They are green organs due to the substance called chlorophyll, a pigment that absorbs solar energy to convert carbon dioxide into oxygen, thereby eliminating polluting gas.

    Roots: It keep the plant steady and upright, also it absorb water and nutrients.

    Flower: It attract insects that polinate the flower.

    Sepals: Protect the unopened flower

    Stamens: The male parts of the flower (each consists of an anther held up on a filament)

    Anthers: Produce male sex cells (pollen grains)

    Stigma: The top of the female part of the flower which collects pollen grains.

    Ovary: Produces the female sex cells (contained in the ovules)

    The parts of a plant and function:
    Roots: they are found under the ground and are attached to the plant, they absorb minerals and water from the soil, they also store food.
    Stem: it is the part of the plant found above the ground, it supports the leaves.
    Leaves: They contain chlorophyll that helps the plants to prepare their food using sunlight, carbon dioxide and water.
    Fruits: are the main features of a flowering plant. It is a matured ovary that develops after fertilization.

    Parts of a flower:

    Sepals: Sepals are green leafy parts present under petals and protect the flower buds from damage.

    Petals: It is the colourful part of a flower which attracts insects and birds.

    Stamens: The male parts of the flower (each consists of an anther held up on a filament)

    Anthers: Produce male sex cells (pollen grains)

    Stigma: The top of the female part of the flower which collects pollen grains

    Ovary: Produces the female sex cells (contained in the ovules)
    Nectary Produce a sugary solution called nectar, which attracts insects

    Pistil: This is the female part of the flower consisting of stigma, style, and ovary.

  10. 1.Stem: Central part that is maintained to the plant from where the branches (secondary stems), the leaves, the flowers and the fruits grow. They are also responsible for transporting water and nutrients from the leaves to the entire plant.
    2.The flower: It is the reproductive organ of plants, it has its origin in flower buds. Its function is to make seeds and is composed of a male part called stamen and a female part called pistil.
    3. The fruit: They are of different sizes, this in relation to the seeds they present. The content that is edible is known as pulp and is characterized by having a sweet flavor.
    4. Leaves: They are green organs due to the substance called chlorophyll, a pigment that absorbs solar energy to convert carbon dioxide into oxygen, thereby eliminating polluting gas.
    5. The root: The root grows underground and its main function is to fix the plant to the ground, absorb the raw sap to carry it to the stem, and is responsible for storing reserve substances.

    parts of a plant

    - filament: support and transport nutrients to the part of the anther
    - style: in this part is where the plant keeps all its ovules that serve to reproduce
    - ovule: It is the reproductive cell of plants that helps it to reproduce
    - sepal: They are helping at an early age to prevent insects from entering the polem
    - anther: in this part is that the processes that give life to the polem happen
    - petal: This part is the most colorful and therefore, most striking, this makes more insects want it and go for it
    - stem: transport water to the diferents parts of the flower
    - leaf: this is one of the most important parts since the photosynthesis process is carried out here
    - root: are what make the plant stay in the ground and receive essential materials from the ground

  13. ROOT:
    Roots are the important, underground part of a plant, which are collectively called the root system. They are the main part that anchors the plant firmly to the ground. They absorb water and minerals from the soil, synthesize plant growth regulators, and store reserve food material. The apical part of the root is covered by the root cap that protects the root apex.

    Direct elongation of the radicle leads to the formation of primary roots that grow into the soil in dicotyledons. It has lateral roots that are known as secondary and tertiary roots.

    Stem
    The stem is the part of the plant that is above the ground. The bark of the trees is brown and the youngest stems are green. It forms the base of the shoot system and carries leaves, fruit and flowers. The region where the leaves arise is known as the node and the region between the nodes is known as the internode.

    The stems emerge from the pen, vertically upwards to the ground. Stems are usually weak initially and cannot stand upright. Eventually it grows to become the hardest part of the plant called the trunk. The trunk is covered by a thick outer covering known as the bark. The general stem provides a defined frame and structure for a plant, which then becomes a tree.

    Leaves
    Leaves are the most important part of a plant. They contain chlorophyll that helps plants prepare their food with sunlight, carbon dioxide, and water. A leaf consists of three main parts: petiole, leaf base, and lamina.

    flowers
    Flowers are the most beautiful and colorful part of a plant. They are the reproductive part of a plant. A flower has four main parts, namely

    Fruits
    Fruits are the main characteristics of a flowering plant. It is a mature ovary that develops after fertilization. Some fruits develop without fertilization and are known as parthenocarpy or parthenocarpic fruits.

  14. 1)The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis of plant growth regulators.
    2)In majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. It bears lateral roots of several orders that are referred to as secondary, tertiary, etc. roots. The primary roots and its branches constitute the tap root system, as seen in the mustard plant.
    3)In monocotyledonous plants, the primary root is short lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant.
    4)In some plants, like grass, Monstera and the banyan tree, roots arise from parts of the plant other than the radicle and are called adventitious roots.
