Cilia- a short, microscopic, hairlike vibrating structure. Cilia occur in large numbers on the surface of certain cells, either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion.
Flagella- a slender threadlike structure, whip-like appendage that enables many protozoa to swim. Cilia and flagella move liquid past the surface of the cell. also helps single celled organisms to swim. Cilia are short eyelash like organelles along the top of the cell while Flagella is a long tail like organelle. Cytoplasm- The material inside of cells, not including the nucleus. Cytoplasm is used to give the cell its shape and to keep organelles in place, without it the cell would be deflated and the materials would not be able to float from one organelle to another. Cytoplasm is a gel like material that fills the cell. Cytoskeleton- a microscopic network of protein filaments and tubules in the cytoplasm of many living cells. The cytoskeleton helps with making shape., unlike the cytoplasm that is just a fluid (filler). It is proteins that look like spider webs all throughout the cell, they look very stretched out because they are helping to keep the cell in its shape. DNA- It is the carrier of genetic information. It is stored in the nucleus of the cell. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. It is used for long term storage of information. DNA exists as a pair of molecules rather than a single molecule. These strands are entwined in the shape of a double helix that is supported by hydrogen bonds. |
