Yes a plant cell membrane acts as a barrier and controls what comes in and what leaves a plant. Many people get it confused with a cell wall but a cell wall keeps the plants shape, and a membrane controls the chemicals.

What cell main job is to control which substances enter and leave a plant cell.?

The cell organelle responsible for controlling which substances enter and leave a plant cell is the cell membrane, specifically the plasma membrane. The plasma membrane is a selectively permeable barrier composed of phospholipids and proteins that regulate the passage of molecules such as nutrients, water, and waste products. Through processes like diffusion, osmosis, and active transport, the plasma membrane maintains cellular homeostasis by allowing essential substances to enter the cell while preventing harmful substances from entering.

Why does a plant cell have a cell membrane?

All cells need to be able to let food, water and unneeded waste to get in and out of the cells, that's where the cell membrane comes in; it acts like a filter letting things in and out. In the animal cell it also has the job of protecting and keeping the cell in place, but in a plant cell the cell wall is given that job.

What is the function of the cell plasma membrane?

The plasma membrane serves as a barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from entering.The plasma membrane surrounds the outside of both Eukaryotic and Prokaryotic cells. It is made up of a double layer of phospholipids and controls the movement of various substances into and out of the cell, both passively and actively. It also allows cell identification.my mommy and your mommy !1. Transport2. Enzyme Activity3.
