Cell Theory and Organelles Flashcard

Front

What is the Cell Theory?

Back

The Cell Theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Who proposed the Cell Theory?

Back

The Cell Theory was proposed by scientists Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.

What are the main differences between plant and animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not.

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to plant cells.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.

Front

What is the function of lysosomes?

Back

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

Front

What do vacuoles do in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the function of the nucleus?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes.

Front

What is the function of the mitochondria?

Back

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