mitochondria
an organelle that harvests energy from organic compounds to make atp
does prokaryotics have a ribosomes
no they have no internal omparments
proteins are produiced by
ribosomes
the maxamum size of cell is determined by
surface area and volume
enzymes does what to chemical reaction
speeds up
protein
a chain of molecules called amino acids linke dtogether like necklace
nucleic acid
long change of nucleotides
phospholipid
made of a phsophate gorup and two fatty acids
nucleotide
3 parts, sugar, base, phosphate group
energy in the body is stored in the form of _______
ATP
does animal cells have chloroplast
no
cell theory

2. cells are the basic units of structure and function in organisms
3. all cells arise from existing cells
lysomes
recycles a cells used components
chromatin
uncoiled and not visible as worm-line
chromosomes
coined up dna, looks like worms
chromotides
replicated dna
centriole
replicates in prophase, right outside nucleaus structure in which the spindle fibers form.
spindle fibers
thin protein fiber that attaches to the centromere of the chromotids, orginates from centriole.
cytokinesis
division of the cell
prophase
centride divies (only in animal), dna coilups chromatids, the nuclear membrane disappears, the spindle fibers form.
anaphase
the chromatids seperate (split away w/ the help of the spindle fibers, now called chromosomes.
telophase
cell divides, cytokinesis - the opposite of prophase happens.
-chromosomes concoil (chromatids)
-spindle fiber disappears
-nuclear membrane forms.
prokaryote
is a single celle dorganism that lacks a nucleaus and other internal compartments
Body Tube
Supports the objective lens system (which is mounted on the movable nosepiece) and the ocular.
nosepeice
Generally, the nosepiece carries three objective lenses. On our microscopes, the nosepiece is rotated to change objective lenses
ribosomes
the cellular structures on which proteins are made
prokaryote or eukaryotic was first existing on earth?
prokaryote
the common example of prokaryote
bacteria
cell wall
sournding the cell membrane that provides structure and support
what two things have a cell wall and cell membrane
prokaryotic and bacteria
eukaryote
an organism whose cells have a nucleus
phospholipid
made of a phsophate gorup and two fatty acids
______ and ______ are found in the lipid bilayer.
protein and enzyme
