A student was observing (looking at) a section (part) of cells under a microscope. She noticed (saw) they had a box-like shape,
bean-shaped organelles and were green. She also noticed (saw) a nucleus that was to the side of the cell. What was she examining? An Animal Cell A virus A bacterium A plant cell
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. <u>This happens because plant cells, besides the membrane, are surrounded by a </u><u>cell wall</u><u>, which is rigid and gives the cell this form</u>.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. <u>The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the </u><u>chloroplast this distinctive green color. </u>
