The chemical equation for photosynthesis: carbon dioxide + water + light energy  glucose + oxygen

The chemical equation for aerobic cellular respiration: glucose + oxygen  carbon dioxide + water + usable energy

PART II TRUE/FALSE All living things do aerobic cellular respiration Only plants do aerobic cellular respiration Only animals do aerobic cellular respiration All living things except plants do aerobic cellular respiration

PART II TRUE/FALSE Elodea cells and human cheek cells are single-celled organisms Elodea cells and human cheek cells are part of multicellular organisms Elodea cells and human cheek cells have chloroplasts Elodea cells and human cheek cells do not have a nucleus

PART II TRUE/FALSE Photosynthesis and cellular respiration occur only in plants Photosynthesis occurs only in plants, and cellular respiration occurs only in animals Photosynthesis occurs in both plants and animals Photosynthesis occurs only in plants, and cellular respiration occurs in both plants and animals

PART III Vocabulary fill in the blank Aerobic cellular respiration turns glucose into usable energy. The stems and leaves in a plant are examples of plant organs. Guard cells control the size of the openings in leaves. The openings in the leaves of plants that regulate gas exchange are called stomata. Photosynthesis takes place in the chloroplasts of the cell.

PART IV Describe Processes When there is little water in the atmosphere, stomata most likely close. The function of xylem in a plant is to transport water to all parts of the plant. The purpose of photosynthesis is to make sugars. Transpiration is an important process in a plant because it delivers water to every cell in the plant. Bacteria and archaea are similar because both are prokaryotes.

PART V Explain Questions How do plant cells that do not have chlorophyll get food? Phloem carries food from the leaves to all the cells in a plant. What is the most significant difference between bacteria and eukaryotes? Eukaryotic cells have a nucleus. How is transpiration related to photosynthesis? Transpiration delivers water needed for photosynthesis to the cells. Mushrooms are part of which domain? Eukaryotes

PART V Explain Questions Why is photosynthesis important to animals? Plants use photosynthesis to make food that animals can eat. What is the range of the number of cells that living organisms can be made of (from the very smallest to the very largest)? One to many millions Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells? The glucose combines with oxygen to make usable energy.
