Q: What are the basic parts of a plant?
The basic parts of a plant include roots, stems, leaves, flowers, fruits, and seeds.
Q: What is the function of roots in plants?
Roots serve to anchor the plant in the soil, absorb water and minerals from the soil, and store excess food.
Q: What are some examples of modified roots in plants?
Examples of modified roots in plants include storage roots (e.g. carrot, sweet potato), aerial roots (e.g. banyan trees), and aquatic roots (e.g. water lily).
Q: What is the Shoot System?
It is the aerial part of the plant body that enables a plant to grow taller to gain access to energy-giving light, and helps plants to prepare food.
Q: What is the function of the Stem in plants?
It supports the upper parts of plants, carries water and nutrients from roots to leaves, and stores food for the plant.
Q: What are Tendrils in plants?
They are coil-like structures found in various climbing plants that help them climb up and grow.
Q: What are Runners or Stolons?
They are stems that grow horizontally above the soil and give rise to new plants if their nodes touch the soil.
Q: What are examples of underground modified stems?
Potato, garlic, onion, and ginger.
Q: What is photosynthesis and where does it occur in plants?
Photosynthesis is the process by which plants produce food using sunlight, water, and carbon dioxide. It occurs in the leaves of the plant.
Q: What is the function of stomata in leaves?
The stomata are tiny openings on the surface of the leaves that help in the exchange of gases, allowing carbon dioxide to enter and oxygen to exit.
Q: Name some modified leaves and their functions.
Spines in cactus for protection, tendrils for support in plants like peas, onion leaves as storage organs, needle leaves in plants like pines for water conservation, and Venus flytrap plants with specialized leaves to capture and digest insects.
Q: What is the function of petals in a flower?
Petals are often brightly colored or unusually shaped to attract pollinators.
Q: What are sepals and where are they located in a flower?
