Lesson 1 and 2 Review: Cell Organelles and Transport

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell, leading to cell shrinkage.

Front

What is the function of the nucleus in a cell?

Back

The nucleus controls the cell's activities and contains the cell's DNA, which carries genetic information.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell, leading to cell swelling.

Front

What is cytoplasm?

Back

Cytoplasm is the gel-like fluid that surrounds and protects the organelles within a cell.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria convert the energy in food molecules into a form that the cell can use, known as ATP (adenosine triphosphate).

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes necessary for the cell's life.

Front

What is the 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 are chloroplasts?

Back

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

Front

What is the function of lysosomes?

Back

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