Pam described two substances which participate in photosynthesis. substance a: combines with carbon dioxide to form sugar substance b: traps sunlight in green plants which statement is correct? substance a is water and substance b is oxygen. substance a is glucose and substance b is water. substance a is water and substance b is chlorophyll. substance a is chlorophyll and substance b is oxygen.

Substance A is water and Substance B is chlorophyll.

Explanation:

Photosynthesis is a process which occurs mainly in plants in which inorganic substances like carbon dioxide (CO2) and water (H2O) combine to form organic substance named as glucose (C6H12O6) which is a sugar. But in order for CO2 and H2O to react with each other energy is required. The source of this energy is sunlight which is captured by a pigment named as chlorophyll which is present in an organelle named as chloroplast of plant cell.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
