Question

Multicellular and Single-celled Unicellular organisms bath have orgnelles, but what does that mean about their structures?

Answer 1

All organisms, whether multicellular or single-celled, have organelles. In multicellular organisms, similar cells come together to form tissues, organs, and organ systems. Single-celled organisms may have organelles that perform functions similar to those of organs in multicellular organisms.

Step-by-step explanation:

All organisms, whether multicellular or single-celled, have organelles. Organelles are small structures within cells that perform specific functions. In multicellular organisms, similar cells come together to form tissues, which then collaborate to create organs and organ systems. For example, in humans, cells in the heart come together to form heart tissue, which then collaborates with other tissues to create the organ known as the heart. In contrast, single-celled organisms may have organelles that perform functions similar to those of organs in multicellular organisms. For instance, Euglena cells have organelles called eye spots and contractile vacuoles that perform functions similar to those of eyes and kidneys in multicellular organisms.
