Question

2. Name the chemical substance found in
following:
(i) Cell wall
(ii) Chromosome
(iii) Ribosome
(iv) Plasma membrane
(v) Lysosome​

Answer 1

Answer:

1)In CELL WALL there is cellulose.

2) CHROMOSOMES have DNA.

3) RIBOSOMES have protein (Amino acids)

4) PLASMA MEMBRANE contains lipids and proteins

5) LYSOSOMES contains digestive Enzymes

Answer 2

hey here is your answer

answer:-

2)

i)cell wall:-The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.

ii)chromosome:-However, as early as the 1920s, scientists agreed that chromosomes were made of two chemical substances-deoxyribonucleic acid (DNA) and protein.

iii)ribosome:-However, as early as the 1920s, scientists agreed that chromosomes were made of two chemical substances-deoxyribonucleic acid (DNA) and protein.

iv)plasma membrane:-The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates.

v)lysosme:-The lysosome contains many digestive enzymes such as proteases, cellulases that help in digesting foreign particles. Cell wall: The plant cell wall is made of cellulose, the bacterial cellwall is made of peptidoglycan while the fungal cell wall is made of pectin.
