power point cell stuff

intracellular fluid

fluid in cell

extracellular fluid

fluid outside cell

interstitial fluid

fluid that is in cavities and bathes organs

plasma membrane

cell’s outer wall

cytoplasm

jelly like stuff where everything sits except the nucleus. all of that is part of the cytoplasm (including organelles and cytosol)

cytosol

liquid in cytoplasm

centrosome

microtubule organizing center used in cell division

organelle example

mitochondria, ribosomes, nucleus, Golgi apparatus

what is cytoskeleton made of

microtubules, microfilaments, intermediate filaments,

microfilament

thinnest part of cytoskeleton, made of actin, helps cell move, divide and change shape

intermediate filaments

strong rope like fiber that anchors down organelles and help cells stay together

microtubules

thick hollow tubes that give cell shape, help with movement, and help with division

nucleus

holds cell dna and controls cell

endoplasmic reticulum

network of tubes and sacs that makes proteins and lipids and moves them around the cell.

rer

rough er dotted with ribosomes. makes proteins that get sent to Golgi

ser

smooth er. stores ca++ makes lipids, breaks down toxins, uses carbohydrates. in cells with lots of hormones

golgi apparatus

mail room of cell, sorts, packages, modifies, transports proteins through vesicles

mitochondria

powerhouse of the cell. generates atp

atp

molecule that stores and gives energy to the cell. a battery

somatic cell

any cell in body that is not a sperm or an egg

reproductive cells

gametes, eggs, sperm
