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, and releasing oxygen as a byproduct.

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. It occurs in the mitochondria of cells.

Front

Why do muscle cells have more mitochondria than skin cells?

Back

Muscle cells have more mitochondria because they require more energy to perform their functions, such as contraction.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, providing energy for primary consumers.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

What type of graph represents logistic growth?

Back

An 'S' shaped graph represents logistic growth, showing how a population grows rapidly at first and then levels off as it reaches carrying capacity.

Front

What is the main function of mitochondria?

Back

The main function of mitochondria is to produce energy (ATP) through the process of cellular respiration.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is the significance of the chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers (plants) to obtain energy, such as herbivores.
