What is photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the blue and red wavelengths, and is essential for photosynthesis.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on the concentration gradient.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

Which macromolecule is primarily responsible for storing genetic information?

Back

Nucleic acids, such as DNA and RNA, are primarily responsible for storing and transmitting genetic information.

Front

What is the function of lipids in biological systems?

Back

Lipids serve various functions, including energy storage, structural components of cell membranes, and signaling molecules.

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.
