Cell Theory
|
1) All living things are made of 1 or more cells; 2) All living things come from preexisting cells through cell division; 3) The cell is the fundamental unit of function/ structure of all living organisms
|
|
|
Cell
|
The smallest unit of all living things
|
|
|
Eukaryotic
|
Has a nucleus
|
|
|
Prokaryotic
|
No nucleus
|
|
|
Nucleus
|
The control center of the cell
|
|
|
Ribosome
|
Constructs proteins in a cell
|
|
|
Rough ER
|
Makes and packages proteins
|
|
|
Smooth ER
|
Assembles and packages lipids
|
|
|
Golgi Apparatus (Bodies)
|
Modifies, stores, and routes cell products
|
|
|
Mitochondria
|
Converts chemical energy into ATP using oxygen
|
|
|
Chloroplast
|
Responsible for photosynthesis in plants
|
|
|
Lysosome
|
Membrane-bound sac containing digestive enzymes that break down proteins, nucleic acids, and polysaccharides.
|
|
|
Vacuoles
|
Membrane-bound sacs that bud from the ER or Golgi Bodies
|
|
|
Vesicles
|
Small membrane-bound sac that moves products into, out of, and within a cell
|
|
|
Cytoplasm
|
Region of cell between nucleus and plasma membrane
|
|
|
Cell Wall
|
In plants, protects the cell and maintains shape
|
|
|
Cell Membrane
|
Responsible for letting things in and out of cell
|
|
|
3 Types of Passive Transport
|
Diffusion, Substances moving from an area of high concentration to an area of low concentration; Facilitated Diffusion, Pathway provided by transports proteins that helps some molecules pass through the cell membrane; Osmosis, Diffusion of water
|
|
|
Isotonic
|
Equal solute
|
|
|
Hypertonic
|
Lower solute
|
|
|
Hypotonic
|
Higher solute
|
|
|
3 Types of Active Transport
|
Endocytosis, Cells ingest materials; Exocytosis, Cells excrete materials; Protein Pump, Moves proteins against the concentration gradient
|
|
|
Cytoskeleton
|
A network of fibers extending throughout the cytoplasm and is always changing its structural pattern. It gives shape and is made up of microfilaments and microtubules
|
|
|
Selectively Permeable
|
Only certain molecules are able to pass
|
|
|
Cilia
|
A lot of short structures that are bundles of microtubules projecting from cell
|
|
|
Flagellum
|
Long, thin structure with a core of microtubules that enable the cell to move
|
|
|
Pseudopod
|
Temporary cytoplasmic projections that can move the cell
|
