Answer 17

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

Question 18

sequence of cell formation?

Answer 18

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

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

Question 20

plasma membrane?

Answer 20

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

Question 21

mitochondria

Answer 21

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

Question 22

cytoplasm

Answer 22

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

Question 23

cytoskeleton

Answer 23

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

Question 24

nucleus

Answer 24

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

Question 25

smooth and rough endoplasmic reticulum (SER)

Answer 25

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

Question 28

Golgi complex

Answer 28

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