Modification, package, and distribution of molecules |
|
|
Centrioles |
Hollow cylinders composed of microtubes |
|
|
Nucleus |
Maintain the heredity information of the species and control cellular activities through protein synthesis |
|
|
Nuclear Envelope |
Two lipid bilayers that separate the nucleus from cytosol |
|
|
Chromatin |
DNA Contains instructions for protein manufacturing Becomes chromosomes during cell division |
|
|
Nucleolus |
Contains DNA that governs synthesis of nRNA |
|
|
Nucleoplasm |
Type of protoplasm that is composed of thick fluid and constitutes chromatin fibers |
|
|
DNA |
Governs all protein synthesis and responsible for perpetuation traits |
|
|
Diffusion |
Passive Movement of molecules from an area of higher concentration to an area of lower concentration |
|
|
Facilitated Diffusion |
Passive Movement of molecules through the cell membrane with the assistance of an integral protein or carrier protein in the bilayer |
|
|
Osmosis |
Passive Movement of water through a semipermeable membrane into a solution where the water concentration is lower |
|
|
Filtration |
Passive Depends on a pressure gradient Increased hydrostatic pressure on a new side of the cell membrane forces the fluid through the membrane |
|
|
Endocytosis |
Active Transports large particles or liquids by engulfing them Phagocytosis-solid Pinocytosis-liquid |
|
|
Exocytosis |
Active Substances to be exported are packaged in vesicles by the endoplasmic reticulum and golgi body Vesicles move through the cytoplasm to the cell surface, fuse with the plasma membrane and release contents into the extracellular fluid |
|
|
Mitosis |
Life cycle of cell |
|
|
Interphase |
Cell is growing, maturing, and differentiating |
|
|
Mitotic phase |
Cell actively dividing |
|
|
1. Prophase |
Chromatic strands coil and condense to form Spindle apparatus forms Nuclear envelope disintegrates |
|
|
2. Metaphase |
Chromosomes line up in the center of the spindle The centromere of each chromosome is attached to a spindle fiber |
|
|
3. Anaphase |
Chromatids are pulled apart by spindle fibers to form a duplicate set of chromosomes The cytoplasm constricts at the metabolic plate |
|
|
4. Telophase |
Chromatin begins to unravel at the polls of the cell A nuclear envelope appears Cytokinesis marks end of telophase |
