Comparative Overview of Cells: Bacteria, Viruses, Amoebas, Plants, and Animals

This article explores the fundamental differences between various cell types including bacteria, viruses, amoebas, and both plant and animal cells. It highlights the characteristics of prokaryotic and eukaryotic cells. Bacteria and viruses are discussed as unicellular entities lacking a nucleus, while eukaryotic cells are defined by the presence of a nucleus. Specific structures like chloroplasts and cell walls in plant cells, as well as their functions in photosynthesis and support, are elaborated upon, along with the roles of vacuoles in maintaining turgor.

Presentation Transcript

  1. 1/27/2014 Cell Comparisons Bacteria, Virus, Amoeba, Plant, & Animal (Eukaryotic and Prokaryotic)

  2. Virus Prokaryotic, Unicellular, single celled, DNA without a Nucleus.

  3. Bacteria Unicellular, single celled, Prokaryotic, DNA with no nucleus

  4. Amoeba Eukaryotic, Unicellular, single celled, Nucleus

  5. Animal Cell Eukaryotic, Multicellular, many cells, Nucleus Plant Cell: Has all the components of animal cells with some additional structures. Chloroplast - Uses sunlight to create food, photosynthesis (only found in plant cells), contains green pigment chlorophyll Cell Wall - outside the cell membrane of plants and some bacteria, the cell wall serves as support Central vacuole - large water container, helps maintain a turgor (stiffness) in the plant http://www.biologycorner.com/bio1/notes_cell.html
