10/25 Cell Processes 2

Front

What is osmosis?

Back

Osmosis is the diffusion of water through a cell membrane.

Front

What process allows sugar to enter a cell against its concentration gradient using energy?

Back

Active transport.

Front

What gas do plants absorb from the atmosphere for photosynthesis?

Back

Carbon dioxide (CO2).

Front

Where does cellular respiration occur in a cell?

Back

In the mitochondria.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

Define diffusion in the context of cell processes.

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

Explain the difference between passive and active transport.

Back

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

Front

What is the primary function of mitochondria in cells?

Back

Mitochondria are responsible for producing ATP through cellular respiration.

Front

What is the significance of the equation 6CO2 + 6H2O + light energy → C6H12O6 + 6O2?

Back

This equation represents the process of photosynthesis, where plants convert carbon dioxide and water into glucose and oxygen using light energy.
