Answer 9

removal from organisms of the waste products of metabolism which
include chemical reaction in cells including respiration taking materials and
substances in excess of requirements

Question 10

Nutrition

Answer 10

taking in of materials for energy, growth and development.

Question 11

Light microscope

Answer 11

a microscope that uses light which shines through the piece of
animal or plant you’re looking at and uses glass lenses to magnify and focus the
image which can magnify up to 1500 times. It is used to make photo micrographs.

Question 12

Cell

Answer 12

the functional and structural basic unit of life

Question 13

electron microscope

Answer 13

a microscope which uses beams of electrons to magnify up
to 500,000 times. It is used in making an electron micrograph.

Question 14

Eyepiece

Answer 14

lens present at the top and is used to see the objects understudy which
have magnification of 10 to 15 times

Question 15

Tube

Answer 15

also called the body tube which connects the eyepiece to the objective lenses

Question 16

Resolving nosepiece

Answer 16

it allows the rotation of lenses while viewing and has holders
for the different objective lenses

Question 17

Coarse adjustment knob

Answer 17

use for focus on scanning

Question 18

Fine adjustment knob

Answer 18

use for focus on Oil. Moves the body tube for focusing the
high power lens

Question 19

Arm

Answer 19

It supports the tube of microscope and connects to the base of the microscope

Question 20

Stage

Answer 20

the platform that is flat used for placing the slides under observation

Question 21

Stage dip

Answer 21

holds the slides in proper place

Question 22

Base

Answer 22

provide basal and support

Question 23

Power switch

Answer 23

the main power station that turns the illumination on and off in a light
microscope

Question 24

Magnification of a diagram

Answer 24

is how many times it is larger than the real object. The
formula is M=I/A

Question 25

Cell membrane

Answer 25

is the partially permeable membrane made up of proteins and fat. It controls what enters and leaves the cell.

Question 26

Cell wall

Answer 26

is made up of cellulose (polysaccharide) and is fully permeable. It protects and supports the cell.

Question 27

Cytoplasm:

Answer 27

is 70% water and consists of proteins dissolved in it for metabolic reactions to take place.

Question 28

Vacuoles

Answer 28

a plant vacuole consists of sugar solution and cell sap. An animal vacuole is called a vesicle and consists of nutrients or water.

Question 29

Chloroplast

Answer 29

present only in plants and contains chlorophyll and starch grains.

Question 30

Nucleus

Answer 30

consists of chromosomes which have DNA.

Question 31

diffusion

Answer 31

the net movement of molecules from a region of their higher concentration to a region of their lower concentration down a concentration gradient, as a result of their random movement.

Question 32

osmosis

Answer 32

is the diffusion of water molecules through a partially permeable membrane(semi-permeable membrane) from a region of high water potential to low water potential.

Question 33

partially permeable membrane

Answer 33

allows small molecules like water to pass through, but not large dissolved solutes.

Question 34

Hypertonic

Answer 34

More solute concentration (low water potential)

Question 35

Water potential

Answer 35

is a property of a solution that describes how free the water molecules are and it’s stored energy of the water molecules before it has to use it for dissolving the solute

Question 36

Isotonic

Answer 36

Equal solute concentration

Question 37

Hypotonic

Answer 37

Less solute concentration (high water potential)
