Which one has a nucleus?
EUKARYOTIC!!!!!!!!
does the SER or RER have ribosomes attached to it
RER- Rough ER
chloroplast function
photosynthesis
hwo do orgainisms increase their sa/v ratio?
folding, shape, division
who lynn margulis
endosymbiosis theory primary biologist
which one is small
prokaryoptes
what are the organelles of the endomembrane system: only have to name three
lysosomes, rer, ser, gogli appartus, vesicles, nuclear envelope
Nucleus function
regulates cells activities (growth, metablosim, etc.), where rna from dna is made, where dna be hanging out
what is sa/v ratio
compares cells total surface area to volume
out of the cystoskeylton protein fibers (mT, mF, If) which is the thickest
Microtubles
how does prokaryotes divide?
via binary fission
what is the endomembrane system
consists of internal membranes and organelles that work to modify transport and package lipids and proteins
nucleolus
inside nuclues, where rRNA is made and combines with proteins to assemble ribosmes
how cell size effect sa/v ratio
As a cell grows, its volume increases faster than its surface area and thats not ideal becuase the cell cant do all its job if too big
what a central vacuole?
hint: plants
helps regulate h20 concetration under changing enivriomental conditions
what does a prokaryotes dna be looking like?
single, circular chromosome
function of golgi appartus
lipids or proteins that still need need further modifies, sorted, packages, and tagged end up here via transport vesicles
mitochondira
site fot conversition of stored energy to ATP, ATP synthesis
wild card: if you can say your fav organelle and its fuction you get point
hope you got points
what is the endosymbiotic theroy
proposes that eukaryotes evolved from prokaryotes. the symbiotic relationship of one englufing the other benefited both cells, eventually leading to the integration of the prokaryotes as permanent organelles within the host cell
name all kingdoms and if they are pro or eu
eu- plants/animals/fungi/protists
pro- bacteria/archaea
WHAT IS A LYSOSOME
contains digestive enzymes that break down large biomolecules and worn out organelles, the trash ans of the cells if you please
Peroxisomes
reactions to break down fatty acids and amino acids occur here also may detoxify poisions
why are we not one big cell?
As a cell becomes larger, the volume of a cell generally increases faster than the surface area, and when the cell becomes too big, it just can't take in enough energy
fuctions of mircofilaments, mircrotubles, and intermediate filaments
iF- structural suport, anchoring orgenles
mT- intracellular transport, cell divison(spindle forming), forming of cilia and flagella
