(b) Cell wall and cell membrane
(c) Centrosome and chromosome
(d) Chloroplast and chromoplast​

Answer 1

i have given answer of a and b

Answer 2

Answer:

(a)

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

(b)

1. Cell membrane is present is all cells while cell wall is only present in plants, bacteria, fungi and algae.

2. Cell wall is made up of cellulose whereas cell membrane is made up of lipids and proteins.

3. Cell wall is non-living whereas cell membrane is living.

(c)

Chromosome: It is the chromatin material during mitosis and meiosis which coils and uncoils itself and carry's all the genetic material and information along it. Centrosome: It is an organelle that is present in the cell and is responsible for the division of the daughter cells in the process of mitosis and meiosis.

(d)

The main difference between chloroplast and chromoplast is that chloroplast is the green coloured pigment in plants, while chromoplast is a colourful pigment whose colour may be yellow or orange or even red.
