Unit 2a: Cell Structure & Functions

Front

What is the function of a chloroplast?

Back

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

Front

What is the primary function of the cell membrane?

Back

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

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and organelles.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and organelles, examples include plant and animal cells.

Front

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

Back

The cell wall provides structural support and protection to plant cells, maintaining their shape.

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 is the nucleus?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What are vacuoles?

Back

Vacuoles are storage organelles in cells that hold various substances, such as nutrients, waste products, or water.

Front

How do plant and animal cells differ in structure?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not; animal cells have centrioles.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.
