Question

Which of the following is not a characteristic of the animal kingdom?

• A. Multicellularity; cells form tissues and organs
• B. Exclusive reliance on sexual reproduction
• C. Motility at some stage of the life cycle
• D. Embryonic development during the life cycle

Answer 1

The correct option is B Exclusive reliance on sexual reproduction

All animals are multi-cellular, made of more than one type of cell, and have an organization of tissues and organs for specialized functions. Animals are also not sessile and are capable of movement at some point in time in their life cycle. Animal tissues of the adult develop from embryonic germ cell layers and hence, animals develop from an embryonic stage to the adult stage. But not all animals reproduce sexually, some animals undergo budding (like in Hydra) other asexual processes for reproduction.

So, the correct option is B.
