  1. Chlorophyll a

  2. Chlorophyll b

  3. Carotene

  4. Phycocyanin
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chlorophyll a is the primary photosynthetic pigment in most freshwater algae, enabling them to capture light energy and convert it into chemical energy through photosynthesis.

Multiple choice

What is the term used to describe the process by which freshwater algae convert carbon dioxide and water into glucose and oxygen during photosynthesis?

  2. Krebs Cycle

  3. Electron Transport Chain

  4. Calvin Cycle
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Calvin Cycle, also known as the light-independent reactions of photosynthesis, is the process by which freshwater algae use energy from ATP and NADPH to convert carbon dioxide and water into glucose and oxygen.

Multiple choice

What is the term used to describe the process by which freshwater algae use light energy to convert carbon dioxide and water into organic compounds?

  1. Glycolysis

  2. Krebs Cycle

  3. Electron Transport Chain

  4. Photosynthesis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Photosynthesis is the process by which freshwater algae use light energy to convert carbon dioxide and water into organic compounds, such as glucose, and release oxygen as a byproduct.

Multiple choice

What is the term used to describe the process by which plants use sunlight, water, and carbon dioxide to produce food?

  1. Photosynthesis

  2. Cellular respiration

  3. Transpiration

  4. Nitrogen fixation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce food. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar that plants use for energy. Oxygen is also produced as a byproduct of photosynthesis.
