Cells and Transport (2021)

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids, and it plays a role in the transport of materials within the cell.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in materials by engulfing them in a vesicle.

Front

What is a vacuole?

Back

A vacuole is a sac within the cytoplasm of a cell that is filled with fluid; it stores substances such as food, water, and waste.

Front

What is the role of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, giving them a rigid, box-like shape.

Front

What happens to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will shrink due to the loss of water.

Front

What is osmosis?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules pass through the cell membrane with the help of transport proteins, without the use of energy.

Front

What are lysosomes?

Back

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

Front

What is the difference between active 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 the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration.
