d) US110 SIS au Duo
b) Plasma membrane and Cell wall difference
Answers
Answer:Plants have both cell wall and cell membrane. Animals only have cell membrane.
Cell Membrane
Semi permeable.
Same size throughout its lifetime. It provides the shape to cell and is flexible.
An organelle of the cell.
It shrinks under drought and gets turgid under high water condition.
It has receptors on its surface which can bind to external chemicals and selectively facilitate it's transfer.
It has a lipid bilayer.
Present in all types of cells ( humans, plants, fungi
Bacterial cell membrane had flagella and pili.
Cell Wall
Impermeable. Doesn't allow any passage.
It's size imcreases. Cell wall has components like cellulose and lignin which helps in maintaining the rigidity of cell wall. Rigidity is attributed to the turgor pressure in cytoplasm.
It is not an organelle of the cell.
Cell wall doesn't shrink under water stress.
Cell Wall lacks any type of receptors.
It doesn't have any lipid bilayer since it doesn't facilitate any sort of transport. It is divided into primary cell wall and secondary cell wall.
Present in plants , fungi, bacteria and archae.
Cell wall has small apertures for flagella and pili.
