Answer:
The functions of the given are :
(a) Plasma membrane
It separates the content of the cell from its surroundings.
It regulates the entry of certain solids and ions into the cell.
It maintains the shape of the cell that is the animal cell.

Synthesis and secretion of enzymes, hormones and etc.
The formation of acrosome of sperm.
(d) Mitochondria
Release of energy form pyruvic acid produced in the cytoplasm in the form of ATP and helps in the Synthesis of respiratory enzymes.
(f) Cytoplasm
Different organelle is contained in it perform different functions.
All metabolic activities occur in it.
Medium of earlier steps of respiration
(g) Asters of centrosome
Present in an animal cell and helps during the process of mitosis.
(h) Chromosomes
Chromosomes carry hereditary information or genes.

Answer:
1: An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner part being folded inwards to form layers (cristae).
2: A minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
3: A short band of tough, flexible fibrous connective tissue which connects two bones or cartilages or holds together a joint.
4: The part of a pistil that receives the pollen during pollination.
5: Each of the segments of the corolla of a flower, which are modified leaves and are typically coloured.
