Modifying the Plasma Membrane

APBIO-KT44V4

Many plants that have evolved in climates where the temperatures fluctuate on a seasonal basis and have evolved several mechanisms for surviving extended periods of cold.

One such mechanism involves the gradual modification of the cell membranes in which phospholipids with saturated fatty acid tails are removed via endocytosis and replaced by phospholipids with unsaturated fatty acid tails.

Which of the following organelles is responsible for this structural modification?

A

The chloroplast.

B

The central vacuole.

C

The smooth endoplasmic reticulum.

D

The Golgi apparatus.
