Cell Structures

Question 1

name types of eukaryotic cells

Answer 1

animal,plant,algae,fungal

Question 2

what organelles are in plant cells that aren’t in animal cells

Answer 2

cellulose cell wall with plasmodesmata
vacuole
chloroplasts

Question 3

what is the cell wall made up of in fungal cells

Answer 3

chitin

Question 4

what organelle is only in animal celland whats its function

Answer 4

lysosomes- hydrolyse phagocytic cells, break down dead cells, digest worn out organelle for reuse

Question 5

name organelles with a single membrane

Answer 5

vacuole, ER, golgi apparatus

Question 6

name 3 organelles which contain DNA

Answer 6

nucleus, chloroplast, mitochondria

Question 7

name organelles which is not membrane bound

Answer 7

ribosomes, cell wall, cytoplasm

Question 8

describe the features of the nucleus and their functions

Answer 8

site of dna replication and transcription (rRNA)
nuclear envelop- double membrane
nuclear pore- allow substance to move between nucleus and cytoplasm
nucleoplasm- jelly-like material
nucleolus- makes ribosomes rRNA

Question 9

describe featuresof mitochondrion and their function

Answer 9

site of aerobic respiration- produces ATP
double membrane- inner membrane folds to form cristae- provides large SA
matrix- control production of proteins, contain enzymes involved in respiration

Question 10

describe features of chloroplasts and their function

Answer 10

site of photosynthesis
chloroplast envelop- double membrane
thylakoid membranes are stacked to form grana- contain chlorophyll
- grana joined together by llamellae
stroma- fluid filled matrix where sugar synthesis happens

Question 11

whats the function of golgi body

Answer 11

processes, modifies, packages new lipids and proteins produced by ER
makes lysosomes

Question 12

whats the function of golgi vesicle

Answer 12

(small fluid-filled sac)
stores lipid and proteins made by golgi apparatus and transports them out of cell

Question 13

whats the funcion of lysosomes

Answer 13

contains hydrolytic enzymes
digests invading cells or break down worn out organelles for reuse

Question 14

whats the function of ribosomes

Answer 14

site of protein sythesis
theres two types- 70s and 80s

Question 15

function of RER

Answer 15

folds and process proteins that have been made at ribosomes
ribosomes- provide large SA

Question 16

function of SER

Answer 16

synthesis and process lipids

Question 17

function of vacuole

Answer 17

maintain pressure inside the cell and keep cell rigid- prevent wilting

Question 18

whats the cell wall of prokaryotic cell made up of

Answer 18

murein-glycoprotein

Question 19

whats the cell division for prokaryotic cells called

Answer 19

binary fission

Question 20

whats the structure of a virus

Answer 20

protein coat called capsid with attachment proteins- attach to receptor of cell

Question 21

whats a capsule

Answer 21

made up of secreted slime which help to protect bacteria from attack by cells of immune system
