What is the most important part of a plant?
Root s. Roots are the most important and underground part of a plant, which are collectively called the root system. They are the major part that anchors the plant firmly in the soil. They absorb water and minerals from the soil, synthesise plant growth regulators, and store reserve food material.
What are the parts of a plant that help them prepare food?
They contain chlorophyll that helps the plants to prepare their food using sunlight, carbon dioxide and water. A leaf consists of three main parts- petiole, le af base and lamina. The petiole keeps the leaf blade exposed to wind and cools the leaf.
What is the function of the petiole?
The petiole keeps the leaf blade exposed to wind and cools the leaf. The leaf base is a protruding part of a leaf. The lamina of the leaf contains veins and veinlets that provide rigidity to the leaf blade and help in the transport of mineral nutrients. Primarily, leaves have three main functions:
How do stems help in reproduction?
Reproduction: A few stems help in reproduction through vegetative propagation and also help to bear flowers and to produce fruits.
What are the functions of stems?
The important functions of a stem include: 1 A stem carries out a number of functions essential for various processes such as photosynthesis. 2 Provides a definite framework and structure to a plant which later develops into a tree. 3 Support: Primary function of the stem is to hold up buds, flowers, leaves, and fruits to the plant. Along with the roots, a stem anchors the plants and helps them to stand upright and perpendicular to the ground. 4 Transportation: It is the part which transports water and minerals from the root and prepared food from leaves to other parts of the plant. 5 Storage: Stems are one of the storerooms of plants where the prepared food is stored in the form of starch. The stems of a few plants in the desert areas, such as Opuntia, get modified into thick, fleshy structures that store food and prevent excessive water loss due to transpiration. 6 Reproduction: A few stems help in reproduction through vegetative propagation and also help to bear flowers and to produce fruits. 7 Guards : Protects Xylem and phloem allowing them to perform their functions. The stem tendrils are spirally coiled and help the plant to climb support. The axillary buds also get modified into thorns that protect the plant from grazing animals. 8 The stems of a few plants in the desert areas, such as Opuntia, get modified into thick, fleshy structures that store food and prevent excessive water loss due to transpiration.
What is the apical part of a root?

Why is it important to conserve water?
Conserving water is advantageous to plants as, among its other functions, it is a reactant in photosynthesis and so is vital to them being able to synthesize food. This food will be used to release energy through cellular respiration. It is ideal for a plant to remain upright as it allows them to access more sunlight.
What is the vacuole in a plant cell?
The vacuole in a plant cell is usually a large structure filled with a liquid called cell sap that consists of water and dissolved substances like sugars or enzymes. Lots of water can be stored in the vacuole, and as the volume of water stored in the vacuole increases, the cell swells.
Why do plants wilt?
Plant cells, like those in the pea, wrinkle and shrink when they have little water available in their surroundings. This causes the plant to wilt. As the availability of water outside the cells increases, however, water will move into the plant cells across the cell membrane by osmosis.
