Cell Theory, Types, and Organelle Functions

Front

What are prokaryotes?

Back

Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are generally smaller and simpler in structure than eukaryotic cells.

Front

What are eukaryotes?

Back

Eukaryotes are organisms whose cells contain a nucleus and other organelles enclosed within membranes. They are typically larger and more complex than prokaryotic cells.

Front

What is a plant cell?

Back

A plant cell is a type of eukaryotic cell that has a defined shape, a cell wall, chloroplasts for photosynthesis, and a large central vacuole.

Front

What is an animal cell?

Back

An animal cell is a type of eukaryotic cell that is generally round or irregular in shape and lacks a cell wall. It contains lysosomes and centrioles.

Front

What is the function of the nucleus?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression and cell division.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What is the function of the cell wall?

Back

The cell wall is a rigid outer layer that provides structural support and protection to plant cells, maintaining their shape.

Front

What are lysosomes?

Back

Lysosomes are membrane-bound organelles in animal cells that contain digestive enzymes to break down waste materials and cellular debris.

Front

What are centrioles?

Back

Centrioles are cylindrical structures found in animal cells that play a key role in cell division by helping to organize the mitotic spindle.

Front

What is the function of the cell membrane?

Back

The cell membrane is a protective barrier that regulates what enters and exits the cell, maintaining homeostasis.
