Front

What is the process called when photoassimilates are temporarily accumulated in the leaf?

Back

Carbon allocation

Front

What is translocation in plants?

Back

The transport of photoassimilates over long distances.

Front

What is the significance of phloem translocation?

Back

It ensures efficient distribution of photosynthetic energy and carbons between organs.

Front

What are the two cell types that make up phloem?

Back

Sieve elements and companion cells.

Front

What is the role of sieve elements in phloem?

Back

They are responsible for transporting sugars throughout the plant.

Front

What do companion cells provide for sieve tube members?

Back

Metabolic support and involvement in the transport of sugars.

Front

What happens during girdling in plants?

Back

It removes the bark, stopping the downward flow of photoassimilate and causing roots to starve.

Front

What is the most common sugar transported in phloem?

Back

Sucrose.
