Question
_____ is present between cytoplasm and cell wall in plant cell.
- Plasma membrane
- Membranous layer
- Organisms
- Cytoplasm granules
Hint:
The plant cell consists of two protective layers before the cytoplasm.
The correct answer is: Plasma membrane
- The plasma membrane is known to be present between the cytoplasm and cell wall in plant cells.
- A plant cell consists of an outer layer of the cell wall which protects it in harsh conditions. It protects it from the outer environment and maintains homeostasis.
- After the cell wall, there is a layer of the cell membrane, also known as the plasma membrane. This helps in the transportation of certain molecules across the membrane. As the plasma membrane is semi-permeable in nature, it only allows certain substances to pass through it and prevent the rest.
- Inside the cell membrane lies the cytoplasm, where all the chemical reactions take place.
The plasma membrane consists of a lipid bilayer with integral proteins embedded in it.
