What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are unicellular organisms without a nucleus or membrane-bound organelles, while eukaryotic cells are multicellular or unicellular organisms with a nucleus and membrane-bound organelles.

What is the Cell Theory?

Back

The Cell Theory states that: 1) All living organisms are composed of cells, 2) The cell is the basic unit of life, and 3) All cells arise from pre-existing cells.

What is an example of a unicellular organism?

Back

Bacteria are an example of unicellular organisms.

Front

What is an organelle?

Back

An organelle is a specialized structure within a cell that performs a specific function, such as ribosomes, mitochondria, and the nucleus.

What does the term 'eukaryote' mean?

Back

Eukaryote means 'with a nucleus', referring to organisms whose cells contain a nucleus.

Front

What are ribosomes and their function?

Back

Ribosomes are organelles that synthesize proteins by translating messenger RNA.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

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 by regulating gene expression.

Front

What are the main components of prokaryotic cells?

Back

Prokaryotic cells typically consist of a cell membrane, cytoplasm, ribosomes, and genetic material (DNA) that is not enclosed in a nucleus.

What is the significance of the cell wall in plant cells?

Back

The cell wall provides structural support, protection, and helps maintain cell shape in plant cells.
