eukaryotic cell structure and function

Question 1

eukaryotic definition

Answer 1

defined nucleus

Question 2

prokaryotic definition

Answer 2

lack of nucleus or membrane bond organelle

Question 3

pilla

Answer 3

prokaryotic move DNA

Question 4

RER and SER

Answer 4

are interchangeable, they are the same

Question 5

cytoskeleton

Answer 5

microtubules and microfillaments

Question 6

central

Answer 6

polarity for cell cycle

Question 7

lysosomes

Answer 7

(digestion)

Question 8

prokysomes

Answer 8

detoxification

Question 9

vacuoles

Answer 9

animals and plant both have them, animals have them when the cell is under stress to put toxins in, but plants have them for storage and to keep turgidity

Question 10

plants

Answer 10

•have chromosomes- thylakoids •have cell walls •plasmodesmata- allows communication

Question 11

primary cell wall (plant)

Answer 11

flexible- •allows plant to move n the wind especially younger plants •has cellulose in polysaccharide matrix with some proteins

Question 12

secondary cell wall (plant)

Answer 12

rigid •high cellulose content •lignin fills spaces. in the cell wall and cross- links polysaccharides for strength

Question 13

plant cells

Answer 13

•have cell walls and membrane •have large vacuoles •regular shape •have chloroplasts •centrioles present only in lower plant forms •has glyoxysomes to convert fatty acids to carbs •contains amyplasts (starch)

Question 14

amyplasts

Answer 14

stach grains.

Question 15

animal plants

Answer 15

•have cell membrane only •7 small vacuoles •irregular shape •no chloroplast •centrioles always present •no glyoxysomes •no amyloplasts

Question 16

nucleus - envelope

Answer 16

•double membrane •separates nucleus from cytoplasm •continuous with lumen of endoplasmic reticulum •inner membrane supported nuclear lamina (protein layer)

Question 17

nuclear pores

Answer 17

aid and regulate exchange of proteins and RNA between nucleus and cytoplasm

Question 18

histones

Answer 18

proteins that aid folding of DNA n chromosomes to tightly pack it
