Solution

1. Plasme membrane

It is present in Prokaryotes and Animal cell, both.

Yes, it is a true organelle. It protects the cell from the environmental conditions, and maintains the movement of substances in and out of the cell.

Structural info: It is made of bilipid layer. The polar head are on the outer side and phosolipid tail on the inner side. It is flexible and has channels made of proteins.

Function: Plasma membrane helps in protecting the cell from environmental conditions. It controls the movement in and out of the cell. It helps in recognition of the cell.

2. Cytosol-

It is present in Prokaryotic and Animal cell, both.

It is a true organelle.

Structural info: It is a fluid like substance, which is present between plasma membrane and organelles. It is composed of salts, water and other organic molecules.

Function: It assists the movement inside the cell. Also, its the site of glycolysis in the cell.

3. Ribosome-

It is present in both Animal and Prokaryotic cell.

It is a true organelle.

Structural info: They are small spherical structures present on two locations- either free in the cytosol or bound with endoplasmic reticulum.

Function: It helps in making proteins.

4. Cell wall-

It is present in Prokaryotic cell only. Animal cells don\'t have cell wall.

It is a true organelle.

Structural info: It is made of cellulose in plants and peptidoglycan in bacterial cells. It is present outside plasma membrane.

Function: It protects the cells from harsh environmental condtions, gives rigid shape and structure to the cells.
