Answer:

hey mate here your answer

Explanation:

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.

(b) Ribosome

Its main function is Protein synthesis.

(c) Lysosome     

Intracellular digestion and Destroy foreign substances.

When a cell is old or injured this rapidly destroy organelles hence called suicide bags.

(e) Golgi apparatus

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.

(i) Glycogen granule

Starch glycogen and fat containing granules serve as food for the cell.

(j) Vacuoles

Storage of water and other substances, food pigments and waste products.

Give turgidity to the plant cell by pressing against a cell wall.

Answer:

a) Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

b) Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.

c) The golgi apparatus modifies proteins and lipids that is receives from the endoplasmic reticulum. These biochemicals leave the golgi by exocytosis before being delivered to different intracellular or extracellular targets.

d) The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

e) When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance. Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
