enter your answer

Explanation:

1. This structure is a key part of simple organisms (like sponges or cnidarians) that handles digestion, nutrient uptake, and gas exchange all in one tissue layer.
2. This structure grows from the parent organism without fertilization, genetically identical to the parent, common in fungi and some animals.
3. This is a protective, cell layer that forms the outermost barrier for many simple animals, acting as a covering.

Answer:

1. Gastrovascular cavity
2. Bud (or spore, depending on organism; bud is common for animals)
3. Epidermis (or ectoderm in embryonic/primitive animals)
