what does dna stand for
deoxyribose nucleic acid
what does rna stand for
ribonucleic acid
proteins are made of
amino acids
lipids are part of
membrane
carbs are made of
sugar
which cell is the smallest?
bacterium
which cell is 2nd smalelst
red blood cellw
which cell is second largest
egg cell
which cell is largest
nerve cell
cell membrane
outer covering, protectice layer
cytoplasm
gelatin like, contains hereditary materialthe
the cytoskeleton is made of
microtubles/microfilaments
cell wall is rigid bc
pectin and lignin
ribosomes produce
proteins
mitochondria releases
energy
energy from mitochondria is stored in
atpa
atp stands for
adenosine triphosphate
golgi bodies
post office
golgi body packages substances into
vesicles
cells have membrane bound spcaes called
vacuoles
passive transport
NO ENERGY
diffusion
high —> low concos
osmosis
passive w/ pater
facilitated diffusion
movement of molecules through emmebrane with proteins
active transport
low conc —> high
endocytosis
takes IN a substance by surrounding it with the membrane
exocytosis
large substances leave the cell with exocytosis —released by vesicle
how shd surface area and volume be related
surface area should be bigger than volume
egg
female sex cell
sperm
male sex cell
diploid cells
have pairs of chromosomes (2)
chromosomes with genes for same traits in same order
homologous chromosomes
egg + sperm + fertilization
zygote
haploid cells
only have 1 chromosome from each pair
after meiosis how many haploid cells does 1 diploid cell become`
4
mitosis/cytokinesis involves how many divisions
one
meiosis involves how many divisions
2
before meiosis a cell goes through
interphase
what is interphase
cell copies its chromosomes
each chromosome is
2 sister chromatids
prophase 1
duplicated chromosomes condense. nucleolus disappears, membrane breaks
metaphase 1
homologous pairs line up, spindle fiber attaches to chromosome
anaphase 1
chromosome pairs separate, are pulled toward opposite ends
telophase 1
membrane forms around each group of duplicate chromosomes. cytoplasm divides through cytokinesis
prophase 2
not copied again, membrane breaks, nucleolus disappears
metaphase 2
pairs of chromatids line up SINGLE FILE
anaphase 2
chromatids of duplicated chromosomes are pulled apart to other ends
telophase 2
nuclear membrane around each set of chromatids, cytoplasm divides —> 4 HAPLOID CELLS FORM
