Transport in Plants Summary

Front

What is the Casparian strip?

Back

A waterproof band made of suberin that prevents further progress of water in the cell walls.

Front

What type of tissue is responsible for transporting water in plants?

Back

Xylem.

Front

What type of tissue is responsible for transporting nutrients and sugars in plants?

Back

Phloem.

Front

What is the function of companion cells in phloem?

Back

Companion cells are packed full of mitochondria to make ATP, which is essential for the active transport of sugars.

Front

What is the role of the cortex in plant roots?

Back

The cortex stores starch and helps in the transport of water and nutrients.

Front

What is the primary function of the endodermis in plant roots?

Back

The endodermis regulates the flow of water and nutrients into the vascular system.

Front

What is the main component of the cell wall in plants?

Back

Cellulose.

Front

What are assimilates in the context of phloem?

Back

Substances such as sugars, amino acids, and hormones that are transported through the phloem.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from roots to leaves, while phloem transports sugars and nutrients from leaves to other parts of the plant.

Front

What is suberin?

Back

A hydrophobic substance that makes up the Casparian strip, preventing water from passing through cell walls.
