AP Bio Unit 2 Organelles

where is the nucleus found

plants and animals

function of the nucleus?

DNA storage, nucleolus is found here

where is the nucleolus found?

eu

function of the nucleolus?

make ribosomes

where is the ribosomes found?

all cells, in cytoplasm and rough ER

function of ribosomes?

makes proteins

where is ER - rough & ER - smooth found?

cytoplasm, EU, nucleus

function of ER - rough?

has ribosomes, protein synthesis (makes proteins)

function of ER - smooth?

makes lipids, cellular detoxification

where is golgi found?

prokaryotic

function of the golgi?

sorts and modifies packages for secret, transports proteins

where is plasma membrane located?

all cells

function of plasma membrane ?

selective barrier, transports nutrients and wastes (phospholipids bilayer)

where is centrisome/centriole located?

eu, animal

function of centrisome/centriole?

organizes microtubules, only functional during cell division

where is cytoplasm located?

both pro & eu, plant & animal

function of cytoplasm?

fluid in cell, aka cytosol

where is cytoskeleton located?

all eukaryotes

function of cytoskeleton?

made of protein filaments, contributes to structure, highway for molecules

where is mitochondria located?

eu & plants & animals

function of mitochondria?

generate energy in form of ATP, lots of folds which increases SA

where is chloroplast located?

plant cells pro and eu

function of chloroplast?

makes foodlike oxygen glucose (sugar), contains chlorophyll (green pigment)

where is lysosome located?

cytoplasm, eu

function of lysosome?

digestion/contains enzymes, recycle, apoptosis/cell death

where is secretory vesicle?

eu

function of secretory vesicle?

transport package & secrete enzymes & molecules, from golgi

where is food vacuole?

any eu cell

function of food vacuole?

gives cells nutrients and stores H₂O and some wastes

where is central vacuole?

eu plants

function of central vacuole?

store water & food, provides turgor purpose

where is cilia located?

eukaryotes

function of cilia?

hair like structure, moves molecules, movement and single celled organism

where is cell wall located?

eu plant & prokaryotes

function of cell wall?

protect cell & structured

where is peroxisome located?

eukaryotic

function of peroxisomes?

produces hydrogen peroxides, detoxifies, and breakdown (similar to lysosome)

where is centromere located?

animal cells

where is extracellular matrix?

all cells

function of extracellular matrix?

liquid surrounding cell, structural support, cell regulation

where is microtubules?

eu

function of microtubules?

hollow, structured, making cytoskeleton, moto proteins move along
