What is Cell Theory?

Back

Cell Theory is a fundamental concept in biology that states: 1) All living things are composed of cells, 2) Cells are the basic unit of structure and function in living organisms, 3) All cells arise from pre-existing cells.

What organelles are found in animal cells?

Back

Animal cells typically contain organelles such as the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, and cell membrane.

Front

What organelles are found in plant cells?

Back

Plant cells contain organelles such as the nucleus, chloroplasts, mitochondria, ribosomes, cell wall, and cell membrane.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they convert glucose and oxygen into energy (ATP) through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that convert sunlight into glucose through the process of photosynthesis.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that provides support for organelles and is the site where many cellular processes occur.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the role of the cell membrane?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is a cell wall?

Back

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