Front

What is photosynthesis in single-cell organisms?

Back

Photosynthesis is the process by which some single-cell organisms, like certain algae, convert sunlight into energy and produce their own food.

What is an example of a single-cell organism that can cause disease?

Back

Bacteria such as Streptococcus can cause diseases in humans.

Front

What is the role of single-cell organisms in ecosystems?

Back

Single-cell organisms play crucial roles in ecosystems, including decomposing organic material and serving as a food source for larger organisms.

Front

How do single-cell organisms reproduce?

Back

Single-cell organisms typically reproduce asexually through processes like binary fission, where one cell divides into two.

What is the difference between prokaryotic and eukaryotic single-cell organisms?

Back

Prokaryotic organisms, like bacteria, lack a nucleus, while eukaryotic organisms, like yeast, have a defined nucleus.
