Plant Structure and Function and Photosynthesis

Front

What is thigmotropism?

Back

Thigmotropism is a plant's growth response to touch or physical contact, often seen in climbing plants that wrap around supports.

Front

What is turgor pressure?

Back

Turgor pressure is the pressure exerted by the fluid in the central vacuole of a plant cell against the cell wall, helping maintain the plant's structure.

Front

What is phototropism?

Back

Phototropism is the growth movement of a plant in response to light, where plants grow towards the light source.

Front

What is hydrotropism?

Back

Hydrotropism is the growth response of plant roots towards moisture or water in the soil.

Front

What is geotropism?

Back

Geotropism is the growth response of a plant to gravity, where roots grow downward and stems grow upward.

Front

What is dormancy in plants?

Back

Dormancy is a period in a plant's life cycle when growth, development, and physical activity are temporarily stopped, often to survive unfavorable conditions.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

What is the importance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and is the foundation of the food chain, providing energy for all living organisms.
