P.) Animal and plant cells Both animals and plants are made up of cells. Their cells have many _________________ in common but there are a few _________________ differences. Let´s look inside a leaf to take a closer look at a plant cell. First, we _________________ a protective cell wall outside the plasma membrane. The cell is made from strong cellulose _________________. Once inside the plant cell we see the large central vacuole which _________________ the composition of the cytoplasm, creates the internal pressure that is characteristic of plant cells, and stores various _________________ produced by the cell. Plants make their own food by photosynthesis in chloroplasts. Light _________________ the two membranes of the chloroplast and strikes these two green discs where light energy is converted to chemical energy. The sugar molecules produced by photosynthesis can be made into other molecules or broken down for energy. All plant cells have mitochondria just like animal cells do. Sugars produced by photosynthesis are broken down and converted to _________________ in mitochondria. Most organelles, like mitochondria, are found in both plant cells and animal cells. So the next time you pass by a plant remember that we have more in common than meets the _________________.
