Question

Animals differ from plants in that they

• A. have heterotrophic mode of nutrition
• B. can sense and respond to stimuli
• C. have a cell wall
• D. have chloroplasts

Answer 1

The correct option is A have heterotrophic mode of nutrition

Unlike plants that can synthesise their own food by the process of photosynthesis, animals depend on other plants or animals for food. Hence, they are heterotrophic. Animals also have other well defined features like a proper nervous system that helps them in sensing the surroundings and responding accordingly. Plants also sense the surroundings and respond to stimuli but in the absence of a nervous system. Animal cells do not have cell walls or chloroplasts. Both these are present in plant cells.
