Cells and Cell Organelles

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, single-celled organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What is the function of a lysosome?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

Front

What is the outermost layer of a plant cell?

Back

The outermost layer of a plant cell is the cell wall, which provides structure and protection.

Front

What is the outermost layer of an animal cell?

Back

The outermost layer of an animal cell is the cell membrane, which controls the movement of substances in and out of the cell.

Front

What are Golgi bodies?

Back

Golgi bodies, or Golgi apparatus, are organelles that modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they break down food molecules to produce energy (ATP) through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that convert sunlight into chemical energy through photosynthesis.

Front

What is the difference between mitochondria and chloroplasts?

Back

Mitochondria break down food to produce energy, while chloroplasts use sunlight to produce food.

Front

What is the cell membrane?

Back

The cell membrane is a semi-permeable barrier that surrounds the cell, controlling the entry and exit of substances.

Front

What is the nucleus?

Back

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