The outer hard covering of a seed is called The outer protective layer of a seed is known as the seed coat. Answer: (b) seed \ coat 2. The process of scattering of seeds away from the mother plant is called The natural process by which seeds are moved away from the parent plant to new locations is called dispersal. Answer: (c) dispersal 3. Carrot and sweet potato can grow new plants from their Carrot and sweet potato are examples of plants that reproduce vegetatively from their modified roots, which store food. Answer: (c) roots 4. Cotton plant grows well in Cotton plants thrive in loamy soil, which provides a good balance of drainage and water retention, along with essential nutrients.

Urea, ammonium sulphate, superphosphates are some common These chemical compounds are used to supply essential nutrients to plants, thereby enhancing their growth and yield. They are classified as fertilizers. Answer: (b) fertilizers 7. Wheat and gram are the examples of Wheat and gram are crops that are typically sown in the winter season and harvested in the spring, characteristic of rabi crops. Answer: (a) rabi \ crops B. Give short answers. 1. Define germination. Germination is the process where a seed begins to grow and develop into a seedling*. It involves the emergence of the radicle (root) and plumule (shoot) from the seed. 2. What are the necessary conditions for seeds to germinate? The necessary conditions for seeds to germinate are adequate water, a suitable temperature, and sufficient oxygen*. Some seeds also require specific light conditions. 3. What is the role of cotyledons in the growth of a seedling? Cotyledons are embryonic leaves within the seed that primarily serve to store food or perform initial photosynthesis*. They provide essential nutrients to the developing seedling until it can produce its own food. 4. What is vegetative reproduction? Vegetative reproduction is a form of asexual reproduction in plants where new plants grow from the vegetative parts* of the parent plant, such as stems, roots, or leaves, rather than from seeds or spores. 5. How does soil affect the growth of plants? Soil affects plant growth by providing physical support, water, nutrients, and air* to the roots. Different soil types influence water retention, nutrient availability, and aeration, which are crucial for plant health.
