The use of these names causes it to be confused with similar-looking plants, like Brazilian elodea (Egeria densa) or hydrilla (Hydrilla verticillata). Similarity between cork cells and epidermal cells, both have a cell wall that is used for protection and structure, - outermost part of the plant cell - provides support to the cell and prevents osmotic lysis, - living part of the cell enclosed by the plasma membrane - contains the cytosol and numerous organs, most prominent structure in the cell, contains genetic information, region of nucleus responsible for producing ribosomal RNA - appears as a dark spot within each nucleus, group of organelles found in plant cells and some protists - surrounded by multiple membranes, contain DNA, control their own replication cycles, and perform specialized functions within the cell, green pigment that is primarily responsible for absorbing light during photosynthesis, A large membrane bound space that stores water and other substances. The entire food chain is based upon the storage of sugar within parenchyma cells. Remove an Elodea leaf and place it in the middle of a microscope slide.
