Photosynthesis, Cellular respiration and Cell Transport

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the main function of the cell membrane?

Back

The cell membrane regulates what enters and leaves the cell, maintaining homeostasis.

Front

Define osmosis.

Back

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

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a membrane.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane.

Front

How are photosynthesis and cellular respiration related?

Back

Photosynthesis and cellular respiration are related because they have opposite equations; photosynthesis produces glucose and oxygen, while cellular respiration uses them.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane without energy.

Front

What is a phospholipid?

Back

A phospholipid is a type of lipid molecule that forms the cell membrane, consisting of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.
