What are the main differences between prokaryotes and eukaryotes?

Prokaryotes lack a defined nucleus and organelles, whereas eukaryotes have these structures enclosed within membranes.

Can algae be classified as prokaryotes?

Most algae are classified as eukaryotes, with cyanobacteria being the main exception as they are prokaryotic.

What role do algae play in the ecosystem?

Algae are crucial for ecosystems as they produce oxygen through photosynthesis and serve as a primary food source in aquatic environments.

Are cyanobacteria harmful?

Some cyanobacteria can produce toxins that are harmful to aquatic life and humans, particularly in stagnant water.
