Question

Which of the following statements are correct about animals?

• A. Animals consume more energy than plants.
• B. Growth in animals is more uniform.
• C. Animals contain more dead cells compared to plants.
• D. Animals have more specialised organ systems than plants.

Answer 1

Answer: (A), (B), (D)

Animals have more specialised organ systems than plants.

• The energy requirement in animals is more than that of plants as they have to move around for food, shelter and mates, and hence they have less number of dead cells.
• Growth in plants is restricted to few regions, whereas growth in animals is more uniform.
• Structural organisation of organs and organ systems is more specialised in animals as compared to plants, due to differences in their modes of life.
