Question

Plants have less energy needs as compared to animals. This is because

• A. they do not move from one place to another
• B. most of their tissues contain dead cells
• C. they do not expend energy
• D. both a&b

Answer 1

The correct option is D

both a&b

The correct option is D.

Explanation of the correct option:

• Locomotion is the feature of animals by which they move from one place to another. The locomotion process requires energy.
• Plants are mostly stationary as they do not move from one place to another, and hence the energy required in locomotion is saved.
• Animals have a skeletal system in the form of bones ( composed of live cells, i.e., osteocytes), which keep them upright and give their body strength. However, in plants, the strength is provided mostly by the dead tissues, especially sclerenchyma.

Explanation of the incorrect options:

Option A:

• Locomotion is one of the features of plants where they save their energy compared to animals.

Option B:

• The presence of dead tissues is one of the two features of plants wherein they save energy compared to animals.

Option C:

• Plants require energy for various processes like growth, photosynthesis, etc.

Energy requirement in plants is quite less as compared to animals due to their inability to move and the presence of dead cells in most of their tissues.
