Front

What are the two structures that limit transpiration in plants?

Back

Stomata and guard cells.

Front

What process do organisms use to maintain a balance between their cells and the external environment?

Back

Homeostasis.

Front

Which function is NOT performed by roots?

Back

Carrying out the light reactions of photosynthesis.

Front

What plant part is responsible for transporting sugars and other nutrients throughout the plant?

Back

Phloem.

Front

Where in the plant are cells specialized for cell division most likely found?

Back

Root tips.

Front

What is the primary function of stomata in plants?

Back

To regulate gas exchange and transpiration.

Front

What role do guard cells play in the function of stomata?

Back

They control the opening and closing of stomata.

Front

What is the main function of roots in plants?

Back

To anchor the plant and absorb water and nutrients from the soil.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from roots to the rest of the plant, while phloem transports sugars and nutrients throughout the plant.

Front

What is the significance of root tips in plant growth?

Back

Root tips contain meristematic tissue, which is responsible for the growth of roots.
