Front

How are photosynthesis and cellular respiration related?

Back

The products of photosynthesis are the reactants of cellular respiration.

Front

What happens during metaphase in mitosis?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is the significance of anaphase in mitosis?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during telophase in mitosis?

Back

During telophase, the chromosomes de-condense, the nuclear membrane re-forms, and the cell prepares to divide.

Front

Define 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 main function of photosynthesis?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.
