Consider the following statements:
1. Plants are autotrophs because they can produce their own food using basic substances like water and carbon dioxide.
2. Animals are autotrophs because they consume food prepared by plants.
3. The process of nutrition in plants involves the use of sunlight, water, carbon dioxide, and minerals to create energy.
Which of the statements given above is/are correct?
Consider the following statements regarding modes of nutrition in plants:
1. Cuscuta is a parasitic plant that relies on its host for nutrients because it lacks chlorophyll.
2. Insectivorous plants primarily obtain their nutrients from the soil, using insects only as supplementary nutrition.
3. Saprotrophs absorb nutrients from dead and decaying organic matter through a process known as saprotrophic nutrition.

2. Pitcher plant - Parasitic plant
3. Mushroom - Saprotroph
4. Lichen - Symbiotic association
How many pairs given above are correctly matched?
Consider the following pairs:
1. Autotrophic Nutrition - Plants creating food using sunlight
2. Heterotrophic Nutrition - Animals producing their own food
3. Photosynthesis - Process of converting carbon dioxide and water into glucose
4. Mineral Nutrition - Animals obtaining nutrients from soil
How many pairs given above are correctly matched?
Consider the following pairs related to the process of photosynthesis in plants:
1. Stomata - Absorb sunlight for photosynthesis
2. Chlorophyll - Captures sunlight energy
3. Transport vessels - Deliver nutrients and water
4. Nucleus - Main site of photosynthesis
How many pairs given above are correctly matched?
What is the primary function of chlorophyll in the process of photosynthesis in plants?
Consider the following statements:
Statement I: Farmers spread manure or fertilisers in fields to replenish nutrients in the soil.
Statement II: Plants absorb minerals and nutrients from the soil, leading to a decline in soil nutrients over time.
Which one of the following is correct in respect of the above statements?
Consider the following statements:
Statement-I:
Plants have the ability to produce their own food, while animals, including humans, cannot. They obtain food from plants or other animals that consume plants.
Statement-II:
Nutrition refers to the process of acquiring and utilizing food by an organism. Autotrophic nutrition is when organisms create food from basic substances, hence plants are known as autotrophs. Animals and most other organisms are heterotrophs that consume food prepared by plants.
Which one of the following is correct in respect of the above statements?
Consider the following statements:
Statement-I: Photosynthesis is the process by which plants produce food, primarily occurring in their leaves.
Statement-II: Living organisms' bodies consist of cells, similar to how buildings are constructed of bricks.
Which one of the following is correct in respect of the above statements?
What is the primary role of nitrogen in plant physiology as described in the text?
