List the structures in the Hydrilla cell that are not present in the human epithelial cell. Hydrilla has chloroplasts and cellulose cell walls and a large central sap vacuole.
b. Are epithelial cells thinner or thicker than Hydrilla cells?
Epithelial cells are thicker than Hydrilla cells
c. Determine the average width and length of three cells (in mm)
Chloroplast: 0.5 mm, cell wall: 1mm and vacuole: 0.8mm
Liver Cells
Liver cells and visible structures
Amoeba
a. Does the organism exhibit all characteristics of living organism?
Yes, well, the basic characteristics of all living things are: contains DNA (genetic material), metabolism and reproduction. Amoeba does all. b. Is the cell membrane of the organism rigid or flexible?
Flexible
Tissues
Tissues observed in the earthworm
Define:
a. Unicellular Organism Any living being consisting of a single cell. Most are invisible without a microscope but a few, such as the giant amoeba, may be visible to the naked eye. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi or yeasts. Some become disease-causing agents (pathogens). b. Colonial
