What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that contains a membrane-bound nucleus and organelles. Examples include plant and animal cells.

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that does not have a membrane-bound nucleus or organelles. Examples include bacteria.

What is the function of the nucleus in a eukaryotic cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site of many cellular processes.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as mitochondria for energy production and ribosomes for protein synthesis.

Front

What is the role of cilia in cells?

Back

Cilia are hair-like structures that help cells move or move substances along the cell surface.

Front

What is the difference between unicellular and multicellular organisms?

Back

Unicellular organisms consist of a single cell, while multicellular organisms are made up of multiple cells that work together.

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.
