Plant cells have chloroplasts which captures the energy from sunlight and converts it into chemical energy. Chlorophyll is the structure that gives a greenish color to a plant. When I saw the inside of the plant cell I saw that there were chloroplasts inside the cell.
Chloroplasts are organelles that capture the energy in a process called photosynthesis. The purpose of the lab is to determine how to compare plant cells and animal cells. Plant and Animal Cells Microscope Lab.

In this lab you will prepare and observe cells from both a plant onion and an animal your own cheek. One of the ways in which plant cells differ from animal cells is that plant cells lack centrioles and do not form asters during mitosis. A spindle forms however and the chromosomes undergo the same kinds of activities as occur in animal cells 6.
