Write 3 functions of each of the following
1. Nucleus
2. Endoplasmic reticulum
3. Golgi body
4 Lysosome
5. Plastid
Answers
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.
(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:
Functions of Nucleus
It controls the heredity characteristics of an organism.
It main cellular metabolism through controlling synthesis of particular enzymes.
It is responsible for protein synthesis, cell division, growth and differentiation.
Stores heredity material in the form of deoxy-ribonucleic acid (DNA) strands.
The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].
Functions of Golgi apparatus:
(i) Material synthesized near ER is packaged and dispatched to various targets inside and outside the cell through golgi apparatus.
(ii) Its function is storage, modification and packaging of products.
(iii) Complex sugars are made from simple sugars.
(iv) Formation of lysosomes.
A lysosome has three main functions: the breakdown/digestion of macromolecules (carbohydrates, lipids, proteins, and nucleic acids), cell membrane repairs, and responses against foreign substances such as bacteria, viruses and other antigens
Plastids are responsible for photosynthesis, storage of products like starch, and for the synthesis of many classes of molecules such as fatty acids and terpenes, which are needed as cellular building blocks and/or for the function of the plant.
