|
Plasma Membrane |
Form: phospholipid bilayer, proteins, hydrophilic head, hydrophobic tail Function: Separates the contents of the cell from it's outside environment, regulates what enters and exits cell |
|
|
Cytoskeleton |
Form: network of proteins Function: structural support, transports cells, in both plants and animals, reinforce cell shape |
|
|
Cell Wall |
Form: fibers Function: protects cell for structural support, distinguished plant vs animal cells |
|
|
Nucleus |
Form: many proteins, DNA, double membrane, contains chromosomes Function: central control center,contains cells genetic instructions encoded in DNA, directing cells for protein systhesis |
|
|
Ribosomes |
Form: Floating in cytoplasm and endoplasmic reticulum, make up proteins Function: where RNA is transformed into protein, responsible for protein synthesis |
|
|
Endoplasmic Reticulum |
Form: interconnected network of flattened membrane enclosed sacs or tubes Function: 2 types of ER: rough and smooth, smooth = doesn't have ribosomes, deals with metabolism, rough = has lots of ribosomes, deals with protein synthesis, overall function = transport of various proteins, specifically carrying them to the Golgi apparatus |
|
|
Golgi Apparatus |
Form: stack of flattened sacs Function: molecules warehouse and processing station for products made by ER, packaging and processing center, send proteins to correct spot |
|
|
Mitochondria
|
Form: outer and inner membranes, phospholipid bilayer and proteins Function: converts chemical energy into ATP, powerhouses of the cell, regulate cell growth |
|
|
Chloroplast |
Form: made of organelles Function: photosynthesis happens here |
|
|
Big Picture of Life & Energy |
1) life needs energy 2) all of our energy comes from the sun 3) cells transform energy |
|
|
Energy |
Energy= ability to work Work= transfer of energy to an object 2 Types of Energy Potential Energy (PE): stored energy Kinetic Energy (KE): energy associated with movement energy in a chemical bond is PE |
|
|
Thermodynamics |
-Study of energy transformation in a collection of matter Laws: 1) Law of Conservation Energy: energy can neither be created nor destroyed under ordinary conditions 2) when energy is transformed from one form to another the amount of useful energy decreases |
|
|
Entropy |
Entropy happens ^tendency of a system to move toward randomness/disorder
-is encountered by sun energy (outside energy) in biological systems |
|
|
Lysosome |
Form: membrane bound structure Function: digestive enzymes |
