Question

1. Given are some differences between the tissues of plants and animals. Which of these

are incorrect differences?

Plant tissue Animal tissue

1. Tissue of plants are made up of lignified and

dead cells.

Tissues in animals are made up of living cells.

2. The structural organization of plants is more

complicated than that of animals.

Structural organization of animals is not

complex.

3. Growth in plants is definite. Growth in animals is indefinite

4. There are dividing and non-dividing tissues

in plants at specific regions.

They do not possess specific regions of

dividing and non dividing tissues.

a) 1, 3 and 4 (b) 2 and 3

(c) 3 and 4 (d) 1, 2 and 3​

Answer 1

b) 2 and 3 show the incorrect differences between the tissues of plants and animals.

Explanation:

• Option 1:
• The vascular tissues are made up of dead cells. The dead cells provide mechanical strength to the plants and do not require much maintenance.
• The animal tissues: epithelial tissue, connective tissue, muscle tissue and nervous tissue are made up of living cells so that they can move and perform several functions.

• Option 2:
• The structural organization of plants is less complex than that of the animal. Different organs in a plant show differences in their internal structure.

• The structure of the animal cells is complex and varies according to their function. Therefore, the tissues are different and are broadly classified into four types: (i) Epithelial, (ii) Connective, (iii) Muscular and (iv) Neural.

• Option 3:
• Growth in plants is indefinite because they have the capacity for unlimited growth throughout their life.

• Animals show growth for a definite period of time and the growth in an animal is diffused. It is limited until the organism matures.

• Option 4:
• Plant tissue is different from those in animals. Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.

• In animals, cell growth is uniform throughout the body. That is why there is no demarcation of dividing and non-dividing regions in animals.

• Hence, options 2 and 3 are incorrect ones.
