Plant Adaptation

Front

What is the primary function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

When do CAM plants typically open their stomata?

Back

CAM plants open their stomata at night to minimize water loss.

Front

What is the main product of carbon fixation in CAM plants?

Back

In CAM plants, carbon dioxide is incorporated into organic acids.

Front

What is the role of sheath cells in C4 plants?

Back

Sheath cells in C4 plants are involved in the process of photosynthesis, where they help concentrate carbon dioxide for more efficient sugar production.

Front

What is the Calvin Cycle and when does it occur in CAM plants?

Back

The Calvin Cycle is a series of biochemical reactions that convert carbon dioxide into glucose; in CAM plants, it occurs during the day.

Front

What happens to C3 plants under extreme heat conditions?

Back

C3 plants can suffer from heat stress, leading to reduced photosynthesis and potentially death.

Front

What are the two main types of photosynthetic pathways in plants?

Back

The two main types of photosynthetic pathways are C3 and C4 pathways, with CAM being a variation of C4.

Front

How do C4 plants differ from C3 plants in terms of carbon fixation?

Back

C4 plants have a specialized mechanism that allows them to fix carbon dioxide more efficiently in high light and temperature conditions compared to C3 plants.

Front

What is photorespiration and why is it a problem for C3 plants?

Back

Photorespiration is a process where oxygen is taken up and carbon dioxide is released, which can reduce the efficiency of photosynthesis in C3 plants, especially under stress.

Front

What adaptations do CAM plants have for water conservation?

Back

CAM plants open their stomata at night to reduce water loss during the hotter daytime.
