Lauren Pundt Brett Scarbrough Abby Russell What is a eukaryotic cell? A cell that contains membrane-bound compartments in which specific metabolic activities take place. Info about the eukaryotic cell… Eukaryotic organisms also have other specialized, membrane-bounded structures, called organelles, which are small structures within cells that perform dedicated functions. All eukaryotic cells have a number of features in common. The eukaryotic cell includes the nucleus, cytoplasm, cell membrane, mitochondria, endoplasmic reticulum, Golgi apparatus, ribosomes, cytoskeleton, centriole. Lauren Pundt Brett Scarbrough Abby Russell What is a prokaryotic cell? Cells that lack a membrane-bound nucleus are called. These cells have few internal structures that are distinguishable under a microscope. Info about the prokaryotic cell…. On the outside they have a strong cell wall. At the center of the prokaryote is the nuclear region, but not separated from the rest of the cell by a membrane. This contains the DNA of the prokaryote, which is a long strand with its ends fixed together. The prokaryotic cell contains the capsule, cell wall, plasma membrane, DNA, flagella and the ribosomes. 3 Differences and in Prokaryotic and Eukaryotic Prokaryotic cells don't have a membrane-bound nucleus and instead of having chromosomal DNA. Their genetic information is in a circular loop called a plasmid. Prokaryotic cells feature three major shapes: rod shaped, spherical, and spiral. Instead of going through elaborate replication processes like eukaryotes. 3 Similarities in Prokaryotic and Eukaryotic Both have cell walls, Cytoplasm, Cytoskeleton. Both cells require a supply of energy. They are both covered by a cell membrane and contain RNA. Lauren Pundt Brett Scarbrough Abby Russell Plant Cells The Plant cell is a Eukaryotic cell. Structures: Nucleus- The powerhouse of a cell Nucleolus- It is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus. Cytosol- Is the liquid found inside cells that is separated into compartments by membranes. Centrosome- An organelle that serves as the main microtubule organizing center Centriole- A barrel-shaped cell structure found in most animal eukaryotic cells, though it is absent in higher plants and most fungi. Golgi Body- Is an organelle found in most eukaryotic cells. Lysosome- Cellular organelles that contain acid hydrolase enzymes to break down waste materials and cellular debris. Peroxisome- Organelles found in virtually all eukaryotic cells. Secretory Vesicle- Membrane bounded vesicle derived from the Golgi apparatus and containing material that is to be released from the cell. Cell Membrane- A biological membrane that separates the interior of all cells from the outside environment. Mitochondrion- A membrane-enclosed organelle found in most eukaryotic cells. Vacuole- A membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells. Cell Wall- The tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. Chloroplasts- Organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Smooth Endoplasmic Reticulum- Found in a variety of cell types and it serves different functions in each. Rough Endoplasmic Reticulum- The portion of the endoplasmic reticulum studded with ribosome that manufactures and transports proteins destined for membranes and secretion. Ribosome- They are the protein-synthesizing machines of the cell. They translate the information encoded in messenger RNA into a polypeptide. Cytoskeleton- a cellular “skeleton” contained within a cell's cytoplasm and is made out of protein. Lauren Pundt Brett Scarbrough Abby Russell Work Cited Page Animal Cells." Biology.
