What is a cell?
A cell is the basic unit of life, encased by a membrane and containing a nucleus and cytoplasm.
What surrounds the nucleus?
The nucleus is surrounded by a jelly-like substance called cytoplasm.
What are stomata?
Stomata are tiny pores on the surface of leaves, surrounded by guard cells.
How do water and minerals reach the leaves?
Water and minerals are transported to the leaves by vessels that run throughout the plant.
What is special about leaves?
Leaves synthesize food through a process called photosynthesis, which other parts of the plant cannot do.
What is chlorophyll?
Chlorophyll is a green pigment in leaves that captures sunlight for photosynthesis.
What is photosynthesis?
Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to synthesize food.
Why is photosynthesis important?
Photosynthesis is essential for food production and oxygen supply, supporting almost all living organisms.
What would happen without photosynthesis?
Without photosynthesis, there would be no food, and the survival of most living organisms would be threatened.
