What happens to cells when pure water is put into their veins?

Back

Cells would expand due to osmosis, as water moves into the cells.

Front

Which cell feature is responsible for transporting ribosomes?

Back

The endoplasmic reticulum is responsible for transporting ribosomes.

Front

What significant discovery was made possible by the invention of the microscope?

Back

The discovery of cells.

Front

What type of transport are diffusion and facilitated diffusion?

Back

Both are types of passive transport.

Front

What is the function of the cell wall?

Back

The cell wall provides structure and protection to the cell.

Front

Front

What is the primary function of the Golgi body?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

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.

Front

What role do lysosomes play in a cell?

Back

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

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plants.
