Question

what is a single celled organism able to do?
grow to large sizes
differentiate
make tissues
survive on its own

Explanation:

Single - celled organisms, also known as unicellular organisms, can perform all life - sustaining functions within a single cell. They do not grow to large sizes like multicellular organisms. Differentiation (the process of cells becoming specialized) is a characteristic of multicellular organisms. Making tissues (groups of similar cells working together) is also a feature of multicellular organisms. However, single - celled organisms can survive on their own as they have all the necessary cellular components to carry out processes like metabolism, response to stimuli, and reproduction.

Answer:

survive on its own
