|
prokaryotic
|
cells with no membrane bound structures
|
|
|
eukaryotic
|
cell with membrane bound structures
|
|
|
cell
|
the smallest unit of living organisms that can perform a life function
|
|
|
All cells have........
|
1.outer membrane
2.cytoplasm 3.genetic material |
|
|
cell wall
|
-only plants, most bacteria
-outer covering, gives protection and shape -cellulose mesh |
|
|
cell membrane
|
-regulates inflow/outflow
-only water can move through the cell -double fatty layer |
|
|
cytoplasm
|
gel state, allows flow of materials and life reactions
|
|
|
cytoskeleton
|
extremely thin protein fiber, for shape and motion
|
|
|
organelles
|
structures in eukaryots, carry out life functions: hereditary info, energy-processing,manufacture of cell substances, processing and transport, recycling
|
|
|
nucleus
|
contains dna, which is the instruction for all cell processes
-chromosome:dna coiled around protein -has an inner membrane |
|
|
mitochondria
|
energy is released from food
-cellular respiration |
|
|
chloroplast
|
contain chlorphyl, capture light energy to food (photosynthesis)
|
|
|
ribosome
|
cells make proteins on ribosomes using dna instruction
-ribos are mostly attached to the ER |
|
|
Endoplasmic Reticulum
|
folded membrane, processes and moves materials around in the cell
|
|
|
golgi bodies
|
package substances from the ER. They are delivered to the cells in vesicles.
|
|
|
vacuoles
|
for storage of food, waste, or water
|
|
|
lysosome
|
break down food, waste and old cell parts , contain digestive enzymes
|
|
|
tissue
|
group of similar cells
|
|
|
organ
|
different tissues, work together
|
|
|
cell theory
|
Cell Theory
Hooke: "cell" Schleiden:all plants have cells Schwan:all animals have cells Virchow:all living things have cells, every living cell comes from a cell |
