Question

9. 16. How do single celled organisms obtain
their nutrition ?​

Answer 1

Answer:

Hey mate here is your answer.

Explanation:

Their cell membranes are selectively permeable. They absorb nutrients from whatever medium they are in. In addition, some single celled organisms engulf other single celled organisms an digest them. It is not only single celled organisms that do this. Some of our white blood cells use this method to get rid of bacteria.

In addition, some single celled organisms have organelles that contain chlorophyl, and carry on photosynthesis.

You might say they get nutrition pretty much all the ways multi celled organisms do. Some even 'hunt'. They are able to sense increasing concentrations of chemicals that are associated with bacteria, etc, and travel toward them, then engulf it and digest it.

Single celled organisms can be quite complex.
