Question

1. the diagram below illustrates the movement of materials involved in a process that is vital for the energy needs of organisms. the process illustrated occurs within a. chloroplasts b. mitochondria c. ribosomes d. vacuoles 24. the photograph below shows a microscopic view of the lower surface of a leaf. what is the main function of the cells indicated by the black pointer? a. regulate the rate of gas exchange b. store food for winter dormancy c. undergo mitotic cell division d. give support to the veins in the leaf 25. the diagram below represents a cell organelle involved in the transfer of energy from organic compounds. the arrows in the diagram could represent the release of atp from a chloroplast carrying out photosynthesis oxygen from a mitochondrion carrying out photosynthesis glucose from a chloroplast carrying out respiration carbon dioxide from a mitochondrion carrying out respiration

Explanation:

1. Photosynthesis occurs in chloroplasts where carbon - dioxide and water are used to produce glucose and oxygen. So the process occurs in chloroplasts.
2. The cells indicated by the pointer are guard cells. Guard cells regulate the opening and closing of stomata, thus regulating gas exchange.
3. Mitochondria are the sites of cellular respiration. During cellular respiration, organic compounds are broken down to release energy, and carbon - dioxide is a by - product.

Answer:

1. A. chloroplasts
2. A. regulate the rate of gas exchange
3. carbon dioxide from a mitochondrion carrying out respiration
