Question

in science class, cindy and jane are conducting an investigation on living things to find out what the difference is between unicellular and multicellular organisms. first, they use a microscope to observe different types of organisms. next, they go to the library to do more research on the organisms they observed with the microscope. afterward, cindy and jane reviewed the observations and data results they recorded to come to a conclusion to the question: what is the difference between a unicellular organism and a multicellular organism? a. unicellular organisms do not respond to stimuli in the environment. multicellular organisms do respond to stimuli in the environment. b. unicellular organisms are producers and multicellular organisms are consumers. c. unicellular organisms perform all functions for life with one cell. multicellular organisms have many cells that work together to keep them alive. d. unicellular organisms are heterotrophs and multicellular organisms are autotrophs.

Explanation:

Unicellular organisms are single - celled and perform all life functions with one cell. Multicellular organisms have many cells that work together for life processes. Option C correctly states this difference. Option A is incorrect as both can respond to stimuli. Option B is wrong because not all unicellular organisms are producers and not all multicellular organisms are consumers. Option D is inaccurate as the feeding type is not the main difference and not all unicellular organisms are heterotrophs and not all multicellular organisms are autotrophs.

Answer:

C. Unicellular organisms perform all functions for life with one cell. Multicellular organisms have many cells that work together to keep them alive.
