Question

Organisms within Kingdom Animalia meet which of the following requirements?

1) They are multicellular
2) They are autotrophic
3) They have a cell wall
4) They reproduce sexually
5) They have chloroplasts

Answer 1

Organisms in Kingdom Animalia are multicellular, heterotrophic, lack a cell wall and chloroplasts, and often reproduce sexually.

Step-by-step explanation:

Organisms within Kingdom Animalia are characterized by several distinct features. To clarify these features, let's go through the requirements listed:

1. They are multicellular, meaning they are made up of more than one cell, unlike unicellular organisms like bacteria.
2. They are not autotrophic; animals are heterotrophic, requiring organic substances or other organisms for food.
3. They do not have a cell wall; animal cells only have a cell membrane, whereas plant cells have a cell wall.
4. Many reproduce sexually, but there are also instances of asexual reproduction in the animal kingdom.
5. They do not have chloroplasts, which are the photosynthetic organelles found in plants and some algae, as animals do not perform photosynthesis.

Therefore, the requirements that are commonly met by organisms within the Animalia Kingdom are being multicellular and lacking both a cell wall and chloroplasts. Additionally, many animals reproduce sexually, and they are heterotrophic.
