Question

multiple choice question
eumetazoans have true tissues, and different types of tissue can interact to form ______, which increase efficiency of body functions and complexity of movement.
cells
colonies
organs
germ layers

Explanation:

• Cells are the basic unit of life. Different types of tissues (which are groups of cells with similar functions) interact to form organs. Organs perform more complex functions than individual tissues.
• Colonies are groups of organisms, not related to tissue - organ formation in the context of eumetazoans.
• Germ layers (such as ectoderm, mesoderm, and endoderm) are embryonic layers that give rise to different tissues, not the result of tissue interaction.

Answer:

organs
