a liquid that has dissolved or can dissolve solute (water)

Question 3

Solution

Answer 3

A solvent with it’s dissolved solutes

Question 4

Diffusion

Answer 4

random movement of molecules of a substance from an area of high concentration to an area of low concentration

Question 5

Osmosis

Answer 5

the movement of a solvent through a selectively permeable membrane from an area of low concentration to and area of high concentration

Question 6

Isotonic conditions

Answer 6

equal movement of solute going in and out of a cell

Question 7

Hypertonic conditions

Answer 7

solute moves into the cell by osmosis (gets smaller)

Question 8

Hypotonic conditions

Answer 8

solute moves out of the cell by osmosis (gets bigger)

Question 9

Answer 9

semi-permeable/
selectively permeable

Question 10

change in weight formula

Answer 10

final weight-initial weight
——————————–x100
initial weight

Question 11

What did distilled water do to the egg

Answer 11

hypotonic, made it get bigger

Question 12

What did 0.35M sucrose do to the egg

Answer 12

Isotonic, stayed the same

Question 13

What did 1M sucrose do to the egg

Answer 13

Hypertonic, got smaller

Question 14

Turgor Pressure

Answer 14

net movement of water into a cell causing the central vacuole to increase in volume, forcing the plasma membrane to push outward, membrane keeps it from bursting

Question 15

Where is anthocyanin stored

Answer 15

central vacuole

Question 16

What happens when you add 3% NaCl to a coral bell plant leaf

Answer 16

causes the pigment to go to the middle of the cell leaving the edges clear

Question 17

Answer 18

Question 19

Chromatin

Answer 19

a combination of DNA and proteins which make up chromosomes

Question 20

Longest phase of the cell cycle

Answer 20

interphase

Question 21

G1

Answer 21

Cell does normal functions and grows

Question 22

S

Answer 22

chromosomes copy

Question 23

G2

Answer 23

normal functions and continues growing

Question 24

major functions for Mitosis

Answer 24

development of an individual from a fertilized egg

Asexual reproduction

Replacement of old or damaged cells

Question 25

Prophase

Answer 25

-chromosomes condense -spindle forms and migrate to opposite end of cell

Question 26

Prometaphase

Answer 26

-nuclear membrane breaks down -spindle grows and attaches to centromere

Question 27

Metaphase

Answer 27

-spindle completely formed -chromosomes line up along the middle of the cell (metaphase plate) -Nuclear membrane is dissolved

Question 28

Anaphase

Answer 28

-centromere of each chromosome separate -Single chromosomes are pulled by their centromeres

Question 29

Telophase in plant cells

Answer 29

-single chromosomes unravel -nuclear envelope begins to form -cell plate forms between cells until they separate

Question 30

Telophase in animal cells

Answer 30

-chromosomes begin to unravel -nuclear envelope begins to form -cleavage furrow forms and pinches the cells till they come apart

Question 31

Diagram vs drawing

Answer 31

a diagram is a theoretical display of what you may see a drawing is showing what you actually see and how it looks
