Q

what do cells express?

A

hereditary info

17
Q

what was the time period for RNA? what does it do?

A

after the solar system but before DNA took over as main catalyst and structure of cells. stores gene intimation and catalyzes chem reaction in old cells

18
Q

sequence of cell formation?

A

eve starts from photocell with heat and cold, RNA catalysts: speed reproduce and strengthen membrane, metabolism starts (chains of chem reactions)

19
Q

3 steps of endosymbiosis?

A

infoldings of plasma membrane, euk consume aerobic bacteria and evo into mitochondrial,

20
Q

plasma membrane?

A

membrane that surrounds a cell and regulates passage of molecules and ions

21
Q

mitochondria

A

eukaryotic organelle that is surrounded by two membranes and site of breathing for the cell and also energy production

22
Q

cytoplasm

A

all the parts of a cell in the plasma membrane, excluding the nucleus

23
Q

cytoskeleton

A

only found in eukaryotic cells and is responsible for the structure, support, locomotion, and transport of materials within the cell

24
Q

nucleus

A

in e cells, contain the chromosomes and surrounded by a double membrane

25
Q

smooth and rough endoplasmic reticulum (SER)

A

(SER) lacks attached ribos, synthesizes lipids and removes toxins
RER - has ribos, syn plasma mem proteins local to ER, Golgi, and lysosomes

26
Q

peroxisome and lysosome

A

in e cells, has enzymes for ox fatty acids and other compounds (takes care of toxins)

27
Q

Golgi complex (also Golgi apparatus)

A

e cell with flat sacs, process and sorts proteins and lipids used for secreting or directed to other organelles

28
Q

Golgi complex

A

it is a eukaryotic org that has fat sacs that process and sort through proteins and lipids secreted or sent to other organelles

29
Q

Louis Pasteur

A

Did: disproved of spontaneous generation since it needed a complex set up in order to prove that there was life, founded organism in air by inventing sealable sealable swan flasks and ultimately, disproved spontaneous generation

30
Q

prokaryote

A

domain either bacteria or archaea and unicellular organism without a nucleus and few organelles

31
Q

eukaryote

A

organism whose cells contain a nucleus, many organelles, and a large cytoskeleton
