Cells(B1.1)

Question 1

Eukaryotic cell

Answer 1

membrane bound organelles

contain genetic information in a nucleus

Question 2

prokaryotic cells

Answer 2

non-membrane bound organelles

Do not contain a nucleus

Their genetic information floats around in the cytoplasm

Question 3

nucleus

Answer 3

controls the cell

contains genetic information

Question 4

cell membrane

Answer 4

Controls what goes in and out of the cell

Question 5

mitochondrion

Answer 5

Where respiration takes place

Question 6

cytoplasm

Answer 6

A jellylike substance where most chemical reactions happens.

Question 7

chloroplast

Answer 7

Contains chlorophyll which is needed for photosynthesis

Question 8

vacuole

Answer 8

contains cell sap,keeps the cell rigid and keeps the cell upright

Question 9

cell wall

Answer 9

outer layer of the cell made from celluose. Makes the wall rigid and supports the cell.

Question 10

What is bacteria?

Answer 10

microscopic single-celled organisms that have the capability of reproducing on their own without a host.

Question 11

flagellum

Answer 11

A long, hairlike structure that grows out of a cell and enables the cell to move.

Question 12

pili

Answer 12

tiny hairlike structures that enable the cell to attach to structures, such as the cells that align to your digestive tract. They also genetic material between bacteria.

Question 13

slime capsule

Answer 13

The layer outside the cell wall in bacterial cells that protects a bacterium from drying out and from poisonous substances. It also helps the bacteria to stick to surfaces.

Question 14

plasmid

Answer 14

circular ring of DNA that is used to store extra genes.

Question 15

What is a light microscope?

Answer 15

A microscope that uses a series of glass lenses and visible light to magnify an image. This microscope magnifies images up to 1,000 times the actual size.

Question 16

methylene blue’s use in microscopy

Answer 16

Used to make it easier to see the nucleus of an animal cell

Question 17

iodine’s use in microscopy

Answer 17

This makes it easier to see plant cell nuclei

Question 18

crystal violet’s use in microscopy

Answer 18

This stains bacterial cell walls

Question 19

The resolution of a microscope

Answer 19

The smallest distance between two points that can be seen as separate entities.

Question 20

Electron microscope

Answer 20

a microscope that focuses a beam of electrons to magnify objects

Question 21

Transmission electron microscope (TEM)

Answer 21

a microscope that passes an electron beam through very thin sections of the sample to produce an image by a beam focusing on it.

Question 22

Scanning Electron Microscope (SEM)

Answer 22

Produces a 3d image of a surface. They send a beam of electrons across the surface of a specimen. The reflected electrons are collected to produce and image.

Question 22

Scanning Electron Microscope (SEM)

Answer 22

Produces a 3d image of a surface. They send a beam of electrons across the surface of a specimen. The reflected electrons are collected to produce and image.
