Question

Question # 24:
Which organisms carry out respiration, growth, movement and excretion?
A all animals and all plants
B animals only
Carthropods and flowering plants only
D plants only​

Answer 1

Answer:

The organisms that carry out respiration, growth, movement and excretion in b) Animals only.

Explanation:

• Respiration is the exchange of life-sustaining gases, such as oxygen between an animal and its environment.
• Gas exchange occurs by diffusion, moving necessary gases like oxygen into animals and taking away waste gases like carbon dioxide.
• The food that animals eat can be transformed into usable energy for cells or can be used to build new cells, which form tissues like skin and muscle. Etc.
• Animal locomotion, in ethology, is any of a variety of methods that animals use to move from one place to another. Some modes of locomotion are (initially) self-propelled.
• Excretion is the process in a living body that gets rid of wastes after taking the required nutrients and minerals from its consumed food.

Answer 2

The correct answer will be option a, all animals and plants.

Respiration: It is a process through which organisms produce energy.

Since both plants and animals need energy for their life processes both show respiration.  

Growth: The growth in animals is determinate that is they only grow till a certain limit whereas that of plants is indeterminate.

Movement: Animals show both locomotion and movement while plants do not show locomotion they only show movement.

Excretion: Different animals have different structures to respire. Plants do not have any specialized structure for respiration, they give out carbon dioxide through stomata.
