Transport & Photosythesis Review

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane, releasing their contents outside the cell.

Front

What is Osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

How do plants primarily absorb water?

Back

Plants primarily absorb water through their roots, which then travels up the stem to the leaves.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis.

Front

What is the ultimate source of energy for living things?

Back

The ultimate source of energy for living things is the Sun.

Front

Define Diffusion.

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is Active Transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What role do stomata play in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
