7 0

Answer:

Explanation:

The structure of a cell membrane is the outer layer of the cell and it contain various cell organelles which are present in both animal and plant cell. It's act as a barrier between the outside environment and cellular content of the cell. It comprises of phospholipid bilayer and integral protein which allow molecules to pass through the membrane and it limits the movement of molecules in the membrane because of it's hydrophobic interior which make the passage of molecules to be selectively permeable.

6.Vacuoles are membrane-enclosed saclike structures that store materials such as water, salts, proteins, and carbohydrates.

7.Storage of materials and support of the cell

11.centrioles

12.cilia

13.Ribosomes are small particles of RNA and protein found throughout the cytoplasm. They are involved in synthesis of proteins.

14. Endoplasmic reticulum

15.Ribosomes are found on the surface of rough ER. Smooth ER has no ribosomes on its surface.

16.The Golgi apparatus is like a customization shop in a factory. It puts the finishing touches on proteins before they leave the factory.

17.If the cell manufactures proteins that are normally released to travel to other cells. Those cells would not receive the proteins. The loss of these proteins might cause the "receiver" cells to function poorly.

19.True

20.Like

21.True

22.Contain

23.walls

24.wood

25.regulates

27.Vesicles transport newly synthesized proteins to the Golgi apparatus. After the Golgi apparatus modifies the proteins, vesicles transport the modified proteins to the cell membrane, where they are released.
