organelles found in cytoplasm
Question | Answer |
---|---|
Ribosomes | tiny particles, each made u of rRNA subunits. they make enzymes and other protien compounds.(protein factories of the cell) |
Endoplasmic Reticulum | a system of membranes forming a network of connecting sacs and canals that wind back and forth through a cells cytoplasm. carries proteins and other substances through the cytoplasm of the cell from one area to another. |
Rough ER | receives and transports newly made protein |
Smooth ER | makes new membrane for the cell |
Goli Apparatus | chemically processes the molecules from the ER then packages them into little vesicles that break away and move slowly out wad into the plasma membrane. makes mucus(chemical processing and packaging center |
Mitochondria | coplex energy releasing chemical reactions occur continuously. these actions supply most of the power of cellular work (power plantsof the cell) the survival of cells and therefore the body depends on mitochondria chemical reactions. each mitochondria has |
(blank) | is own DNA somtimes called mitochondrial chromosome, which contain information for building and running the mitochondrion. |
aerobic or cellular respiration | the process in which oxygen is used to break down glucose and other nutrients to release energy required for cellular work(occurs in the mitochondria) |
Lysosomes | contain enzymes that can digest food compounds (digestive bags), can protect cells aginst destruction by microbes. |
centrioles | rod shaped structures, play an important role in cell division |
Microvilli | finger like projections of the plasma membrane. increase the surface area of the cell and thus increase its ability to absorb substances. |
Cilla | extremely fine hair like extentions on the exposed or free surfaces of some cells. capable of movement. one cell may have a hundred or more cilia capable of moving together in a wave like fashion over the suface of a cell. |
Flagella | Single, (Flagellum). a single projection extending from the cell surface. much larger than cilla.ex. the tail on male sperm. make it possiable for the sperm to swim |
Nucleus | ultimately controls eery organelle in the cytoplasm. it also controls the complex process of cell reproduction |
Nucleolus | critical in protein formation, because it programs the formatin of ribosomes in the nucleus. the ribosomes then migrate through the nuclear envelope into the cytoplasm of the cell and produce proteins. |
Chromatin granules | thread like structures made of proteins and hereditary molecules called DNA |
