Cells Unit Review (Honors)

Front

What is the primary site of protein synthesis in a cell?

Back

Ribosomes are the primary site of protein synthesis in a cell.

Front

What is the main characteristic of active transport?

Back

Active transport requires energy to move substances against their concentration gradient.

Front

What structure provides shape and support to plant cells?

Back

The cell wall provides shape and support to plant cells.

Front

Which organelles are responsible for cellular respiration?

Back

Mitochondria are the organelles responsible for cellular respiration.

Front

What happens to plant cells when salt is added to them?

Back

Water will move out of the eggplant cells, causing the cells to shrink.

Front

Define diffusion in the context of cellular processes.

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

Explain the difference between passive and active transport.

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What role do mitochondria play in a cell?

Back

Mitochondria are responsible for producing ATP through cellular respiration.

Front

What is the function of the cell membrane?

Back

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