The root system of a plant is responsible for absorbing water and nutrients from the soil, anchoring the plant in place, and storing reserve food materials. The main components of a root system include the primary root, lateral roots, root hairs, and root cap.

- Primary root: The primary root is the first root that emerges from the seed upon germination. It grows vertically downward into the soil to anchor the plant and absorb water and nutrients.

- Lateral roots: Lateral roots branch off from the primary root and grow horizontally in the soil. They help to increase the surface area for absorption of water and nutrients.

- Root hairs: Root hairs are small, hair-like structures that grow from the root surface. They greatly increase the surface area for absorption and are responsible for taking in water and nutrients from the soil.

- Root cap: The root cap is a protective layer of cells at the tip of the root. It helps to protect the delicate growing tip of the root as it pushes through the soil and also plays a role in sensing gravity and moisture in the soil.

The stem of a plant provides support for the plant, transport of water and nutrients, and storage of food materials. The main components of a stem include nodes, internodes, buds, leaves, and vascular bundles.

- Nodes: Nodes are points on the stem where leaves, branches, and buds are attached. They are important for growth and development of new shoots and leaves.

- Internodes: Internodes are the segments of the stem between two nodes. They provide support and spacing between leaves, branches, and flowers.

- Buds: Buds are small, undeveloped shoots that can grow into new branches, leaves, or flowers. They are important for the growth and development of the plant.

- Leaves: Leaves are the main organs of photosynthesis in plants. They contain chlorophyll, which captures sunlight and converts it into energy for the plant to use.

- Vascular bundles: Vascular bundles are bundles of xylem and phloem tissues that transport water, nutrients, and sugars throughout the plant. They are located in the stem and connect to the roots and leaves.

The leaves of a plant are responsible for photosynthesis, transpiration, and gas exchange. The main components of a leaf include the blade, petiole, veins, stomata, and epidermis.

- Blade: The blade is the flat, green, photosynthetic part of the leaf. It contains chloroplasts, which are responsible for capturing sunlight and converting it into energy.

- Petiole: The petiole is the stalk that attaches the leaf to the stem. It provides support and allows the leaf to be positioned for maximum sunlight exposure.

- Veins: Veins are vascular bundles that run through the leaf and provide support for the leaf structure. They transport water, nutrients, and sugars throughout the leaf.

- Stomata: Stomata are small openings on the underside of the leaf that allow for gas exchange. They also regulate the flow of water vapor out of the leaf through transpiration.

- Epidermis: The epidermis is the outermost layer of cells on the leaf. It provides a protective barrier against pests and diseases and helps to regulate water loss through transpiration.
