Biology Fall Final Practice

Front

What is the benefit of regulating the cell cycle in multicellular organisms?

Back

Regulating the cell cycle allows multicellular organisms to replace lost cells, such as shed skin cells and heal wounds.

Front

What role does light play in photosynthesis?

Back

Light provides the energy for assembling small molecules into sugars during photosynthesis.

Front

What is the main role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is used to assemble sugars, the main product of photosynthesis.

Front

What characterizes a prokaryotic cell?

Back

A prokaryotic cell is characterized by the absence of a nucleus and membrane-bound organelles.

Front

Where does the Krebs cycle occur in a cell?

Back

The Krebs cycle occurs in the matrix of the mitochondria.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

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 cellular respiration?

Back

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

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, where energy production occurs through cellular respiration.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.
