Answers
Answer:
A. Nucleus: contains genetic material and controls all the activities of the cell. It is placed in the center of the cell.
B. Cytoplasm: A semifluid substance that contains all cellular organelles helps in movement of substance within and to the exterior of the cell. It is evenly distributed in the place between the nuclear membrane and plasma membrane.
C. Plasma membrane: Outer limiting membrane in a animal cell. Provides shape to the cell, helps in exchange of material between the cell and its exterior.
D. Vacuole: A single membrane structure, very small, few in an animal cell. Stores ions, waste products etc
E. Nucleus: It contains genetic material, controls all the activities of the cell. In a plant cell it is pushed to the periphery.
F. Cell wall: The cell wall is the outermost boundary/layer of a plant cell. It is present exterior to the plasma membrane. It is completely permeable to water, ions and other substances. It provides rigidity and shape to the cell.
G: Cell membrane: Cell membrane is present inner to the cell wall. It is selectively permeable.
H: It is the space between the cell wall and the cell membrane
I: chloroplast: A plastid exclusively present in a plant cell. It is responsible for photosynthesis.
