Front

How many chromosomes do fruit fly body cells have?

Back

Fruit fly body cells have 8 chromosomes.

Front

What happens to a plant cell if all mitochondria are removed?

Back

The plant cell will be unable to carry out respiration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special proteins.

Front

What is the function of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during cell division.

Front

What is the role of the cellular membrane?

Back

The cellular membrane provides support and protection for the cell while controlling the movement of materials in and out of the cell.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What are ribosomes responsible for?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the function of the nucleus?

Back

The nucleus is the control center of the cell that contains genetic material (DNA) and regulates cell activities.
