Bio S1 Review 24-25

Front

Where does photosynthesis occur in plants?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the main pigment that absorbs light energy for photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O -> C6H12O6 + 6O2 represents the process of photosynthesis, converting carbon dioxide and water into glucose and oxygen.

Front

What does an ecological pyramid show?

Back

An ecological pyramid illustrates the relative amounts of energy, biomass, or numbers of organisms at each trophic level in an ecosystem.

Front

What is primary succession?

Back

Primary succession is the process of ecosystem development that occurs on surfaces where no soil exists, such as after a volcanic eruption.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for converting carbon dioxide and water into glucose during photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs on bare rock or soil, while secondary succession occurs in areas where an ecosystem has been disturbed but soil remains.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What is the significance of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.
