Cell Organelle Pre-Flashcard

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, acting as a barrier and gatekeeper.

Front

What organelle is known as the 'gatekeeper' for plant and animal cells?

Back

The cell membrane is known as the 'gatekeeper' because it regulates the movement of substances in and out of the cell.

Front

What part of the cell stores DNA?

Back

The nucleus stores DNA, which contains the instructions for making proteins.

Front

Which organelle uses sunlight to produce sugar?

Back

Chloroplasts use energy from sunlight to convert carbon dioxide and water into sugar through photosynthesis.

Front

What organelles are unique to plant cells?

Back

Chloroplasts and the cell wall are unique to plant cells.

Front

What is the role of mitochondria in the cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate energy in the form of ATP through cellular respiration.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis, translating genetic information into proteins.

Front

What is the purpose of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids; it can be rough (with ribosomes) or smooth (without ribosomes).

Front

What is the function of the cell wall?

Back

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

Front

What is the role of vacuoles in plant cells?

Back

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