9.The cytoplasm, cell membrane and the nucleus are the 3 main parts of a cell. Cytoplasm is the part of the cell that contains the organelles and all the other components of the cell. The cell membrane or the plasma membrane acts as a barrier which only allows selective movement of substances into or out of the cell and the nucleus of the cell is the part that contains all the genetic information necessary for the cell to function.
10. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

9 . The three main parts of cell are:
☆cytoplasm- The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells .
☆Nucleus- a usually round part of most cells that is enclosed in a double membrane, controls the activities of the cell, and contains the chromosomes.
☆cell membrane-The cell membrane is the semipermeable membrane of a cell that surrounds and encloses its contents of cytoplasm and nucleoplasm.
