Question

Differentiate between
(a) Cell wall and cell membrane
(b) Leucoplast and chloroplast
(c) Vacuole in a plant cell and an animal cell
(d) A tissue and an organ

Answer 1

Explanation:

1. Cell Wall :

• It is made up of cellulose
• It provides an extra protection

2. Cell membrane :

• It is a lipo protein in nature. It is made up of lipid bi layer.
• It protects the inner components of a animal cell.
• It is selectively permeable.

1. Leucoplast :

• It is present in the storage organs of a plant.

2. Chloroplast :

• It is present in the leaf and provides colour to the leaf

1. Vacuole in plant cell :

• It takes up 70 - 90% space in a plant cell and is quite large.

2. Vacuole in animal cell :

• In animal cells vacuole are small.

1. Tissue :

• It is made up of a group of cells.

2. Organ :

• It is made up of a group of tissues.

Answer 2

Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
