We reviewed the similarities and differences between plant and animal eukaryotic cells. We created a booklet and participated in a few other activities to help us remember the organelles contained in each cell. Then we looked deeper at the process of photosynthesis performed by the chloroplasts in plant cells. We learned that chloroplasts contain a green pigment called chlorophyll which captures energy from sunlight. Then this light energy combines carbon dioxide and water which forms the sugar glucose and oxygen gas. Plants break down glucose for energy and store excess sugars in the roots and stem. Plant cells are very different from animal cells in that they make their own food. The oxygen and sugar that the chloroplasts produce is needed for mitochondria to perform cellular respiration. The products of photosynthesis are the starting materials for cellular respiration just as the products of cellular respiration are some of the materials needed for photosynthesis.
