Which of the following is not a characteristic of animals?

• A. Multicellularity
• B. Heterotrophic nutrition
• C. Ability to move at some stage of life
• D. Cell walls made of cellulose

Answer: (D)

Verified step by step guidance

1. Begin by understanding the characteristics that define animals. Animals are multicellular organisms, meaning they are composed of multiple cells that work together to form tissues and organs.
2. Next, consider the nutritional aspect. Animals are heterotrophic, which means they obtain their food by consuming other organisms, unlike plants that are autotrophic and produce their own food through photosynthesis.
3. Another characteristic of animals is their ability to move at some stage of their life cycle. This movement can be through various means such as swimming, flying, or walking, and is often facilitated by specialized structures like muscles and limbs.
4. Now, examine the characteristic related to cell structure. Animals do not have cell walls made of cellulose. This is a feature of plant cells, which have rigid cell walls composed of cellulose to provide structural support.
5. Finally, identify the characteristic that does not belong to animals. Since animals do not have cell walls made of cellulose, this is the correct answer to the question of which characteristic is not associated with animals.
