Prokaryotic & Eukaryotic Cells

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What is a eukaryotic cell?

Back

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

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What are unicellular organisms?

Back

Unicellular organisms are living entities that consist of a single cell. Prokaryotes are exclusively unicellular.

Front

What are multicellular organisms?

Back

Multicellular organisms are living entities that consist of multiple cells. Examples include plants and animals.

Front

What is the function of the plasma membrane?

Back

The plasma membrane controls the movement of substances in and out of the cell, providing protection and support.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and ribosomes.

Front

What is the role of the nucleus in eukaryotic cells?

Back

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

Front

What is cytoplasm?

Back

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

Front

What is a cell wall?

Back

A cell wall is a rigid outer layer found in plant cells and some prokaryotes that provides structure and protection.
