Front

What are eukaryotic cells?

Back

Front

How do primary producers generate energy?

Back

Primary producers generate energy through chemosynthesis and photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms create energy by using chemical reactions, often in the absence of sunlight.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy (e.g., animals).

Front

What are the main components of a cell?

Back

The main components of a cell include the cell membrane, cytoplasm, nucleus, and organelles.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.
