D Correct answer
Explanation

Plants respond to their environment to ensure their survival. Plants response to environment is mainly through growth, either towards or away from stimuli. This type of response is called as tropism. It is brought about by hormones, which control plant growth and development.

Thus, the correct answer is option D.

Growth occurs when 

  1. Anabolism is higher than catabolism

  2. Catabolism is higher than anabolism

  3. Protoplasmic synthesis is more than apoplasmatic synthesis

  4. Apoplasmatic synthesis is more than protoplasmic synthesis

A Correct answer
Explanation

Growth occurs when the anabolic (Constructive activities) exceed the catabolic activities (destructive activities).

So the correct option is A.

Growth occurs when

  1. Anabolism is higher than catobolism

  2. Catabolism is higher than anabolism

  3. Protoplasmic synthesis is more than apoplasmatic synthesis

  4. Apoplasmatic synthesis is more than protoplasmic synthesis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The irreversible permanent increase in size, volume or weight of the body is called Growth. It is the cumulative effect of cell division, cell elongation and cell differentiation. During growth, in the cells, rate of metabolism is high. So, synthesis and breakdown of biomolecules takes place. In this synthesis of biomolecules is higher than breakdown of biomolecules. So the rate of anabolism is greater than catabolism.

So, correct option is ‘Anabolism is higher than catabolism’.

Substances synthesised during growth are

  1. Protoplasmic

  2. Apoplasmic

  3. Protoplasmic and apoplasmatic

  4. Nucleic acids
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The irreversible permanent increase in size, volume or weight of the body is called Growth. During synthesis of protoplasmic and non protoplasmic substances takes place. Synthesis of the protoplasmic substances is called protoplasmic growth and synthesis of non protoplasmic  substances(cell wall) is called apoplasmic growth.

So, the correct option is ‘Protoplasmic and apoplasmic’

Generally growth and reproduction are

  1. Mutually inclusive events

  2. Mutually exclusive events

  3. Either a or b

  4. None
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Increase in the size of an organ or body is called growth, whereas the formation of progeny from a parent is called reproduction. So in a living organism growth and reproduction simultaneously occur.

So, the correct answer is ‘Mutually inclusive events ’.

The growth of the root and stem in length with the help of apical meristem is called _________

  1. Primary growth

  2. Secondary growth

  3. Secondary and primary growth

  4. Reproductive growth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Primary growth is the increase in the length of root and shoot. It is the result of cell division of apical meristem. 


So, the correct option is 'Primary growth'.
