Chapter 4

Question 1

Cell theory

Answer 1

All living things are composed of cells and that all cells come from earlier cells

Question 2

every cell and every organism on earth was formed

Answer 2

by a previous cell

Question 3

Two daughter cells

Answer 3

two identical cells that are produced when a single parent cell divides through the process of mitosis

Question 4

every cell in your body

Answer 4

was formed by a devision of a previous cell

Question 5

Prokaryotes-single celled organism

Answer 5

do not have a membrane-bound nucleus to contain their DNA. (but it does have a membrane

Question 6

Example of Prokaryote cells

Answer 6

bacteria and archea

Question 7

Eukaryotic cells

Answer 7

cell or organism that possesses a clearly defined nucleus.

Question 8

Did you know

Answer 8

Eukaryotic cells are usually larger than prokaryotic cells

Question 9

examples of eukaryotic cells

Answer 9

plants, animals, fungi,protists

Question 10

ALL CELLS

Answer 10

have a cell membrane, cytosol(fluid filled in membrane), DNA,Ribasomes

Question 11

Ribosomes make

Answer 11

protein

Question 12

nukleoid/nucleus

Answer 12

where you find the DNA

Question 13

prokaryotic cells are much ____ than eukaryotic cells

Answer 13

simpler

Question 14

cytoplasm

Answer 14

the inside of the sale

Question 15

polar

Answer 15

hydrophilic

Question 16

non polar

Answer 16

hydrophobic

Question 17

nuclear envelope

Answer 17

double membrane

Question 18

DNA

Answer 18

never leaves the nucleus

Question 19

Nuclear pores

Answer 19

protein-lined channels in the nuclear envelope that regulate the movement of molecules between the nucleus and the cytoplasm of a cell

Question 20

All cells in your body

Answer 20

have the same amount of DNA, but not all use the same amount

Question 21

mRNA

Answer 21

leaves the nucleus

Question 22

negative feedback group

Answer 22

a regulatory mechanism that helps maintain a stable state, or homeostasis, by counteracting a change in a system

Question 23

Rough ER

Answer 23

endoplasmic reticulum

Question 24

Rough Er

Answer 24

is a single membrane, has ribosomes on the outside that gives it a rough appearance

Question 25

Golgi apparatus

Answer 25

a cell organelle that modifies and packages proteins and lipids for use inside and outside the cell

Question 26

The way protein moves in a cell

Answer 26

DNA transcribes to RNA, then the Ribosome translates that information into a polypeptide, rough Er (where protein synthesize), then transport vessel, the Golgi apparatus then does processing packing and shipping and finally the process of exocytosis

Question 27

exocytosis

Answer 27

the way protein gets out

Question 28

animal cells do not have

Answer 28

a cell wall, but plant cells do

Question 29

cellulose fibers

Answer 29

give cell walls structure

Question 30

double membrane

Answer 30

nucleus, mitochondria, and chloroplasts

Question 31

chloroplasts

Answer 31

absorb light energy through Co2 + H20- make glucose and oxygen (as waste)

Question 32

mitochondria

Answer 32

the inner membrane is folded

Question 33

difference between mitochondria and chloroplasts

Answer 33

chloroplasts - 2 true outer membranes plus another one that makes up internal structure Mitochondria 2 membranes overall, one outer and one that folds

Question 34

mitochondria

Answer 34

uses glucose to convert into ATP

Question 35

Plant cells have

Answer 35

both mitochondria and chloroplasts

Question 36

lysosome

Answer 36

membrane-bound organelle within a cell that contains digestive enzymes, responsible for breaking down waste materials, worn-out cell parts, and foreign substances like bacteria
