Answer 1

Answer:

a.The cell membrane surrounds the cytoplasm of living cells, physically separating the intracellular components from the extracellular environment. ... The cell membrane is selectively permeable and able to regulate what enters and exits the cell, thus facilitating the transport of materials needed for survival.

b. Protoplasm, the cytoplasm and nucleus of a cell.

c.It provides protection to the cell and prevents from any physical damage.

It provides structure to the cell

d.All eukaryotic cells have within them a functionally interrelated membrane system, the endomembrane system which consists of the nuclear envelope, endoplasmic reticulum (ER), Golgi apparatus, vesicles and other organelles derived from them (for example, lysosomes, peroxisomes), and the plasma membrane.
