Question 1

What bacteria causes strep throat?

Answer 1

Streptococcus

Question 2

What are the oldest life forms on earth?

Answer 2

Archaebacteria

Question 3

Name two types of bacteria that can make your sick:

Answer 3

Salmonella and Streptocuccus

Question 4

What part of the bacteria cell helps it stick to surfaces?

Answer 4

Pilus(i)

Question 5

Name two foods that bacteria help make

Answer 5

cheese and yogurt

Question 6

What does “decompose” mean

Answer 6

break down

Question 7

What is the control center of the bacteria cell

Answer 7

chromosome/ DNA (not surrounded by a membrane)

Question 8

What part of the bacteria cell helps it move?

Answer 8

flagellum(a)

Question 9

Where do Archaebacteria live?

Answer 9

extreme environments

Question 10

To what kingdom do common bacteria belong?

Answer 10

Eubacteria

Question 11

Cell membrane function

Answer 11

boundary of the cell, moves substances in and out

Question 12

Endoplasmic Reticulum function

Answer 12

transports materials throughout the cell

Question 13

ribosome function

Answer 13

makes protiens

Question 14

Golgi apparatus function

Answer 14

packages, processes, and exports proteins as vesicles

Question 15

Lysosome function

Answer 15

contains digestive enzymes to break substances down

Question 16

Microtubule function

Answer 16

framework of the cell, part of the cytoskeleton

Question 17

Mitochondria

Answer 17

harvests energy in the form of ATP, “powerhouse” of the cell

Question 18

Nucleus

Answer 18

contains the DNA, which provides instructions for making proteins; control center

Question 19

3 things in a plant cell that are not found in an animal cell:

Answer 19

cell wall, chloroplast, central vacuole

Question 20

How does the shape of a plant cell differ from that of an animal cell?

Answer 20

plant cells tend to be square or rectangular (due to cell wall); animal cells tend to be spherical

Question 21

chloroplasts function

Answer 21

chloroplasts absorb light, used in photosynthesis

Question 22

vacuole function

Answer 22

stores water (also involved in plant turgor pressure)

Question 23

mitochondria function. Why do plants need both chloroplasts and mitochondria?

Answer 23

mitochondria supply energy for the cell/ chloroplasts are used to make glucose, which is then used in cellular respiration by the mitochondria to make ATP

Question 24

Cell Division

Answer 24

Occurs in a series of stages, or phases

Question 25

Interphase

Answer 25

Chromosomes are copied (#doubles)= replication
Chromosomes appear as threadlike coils (chromatin) at the start, but each chromosome and its copy (sister chromosomes) change to sister chromatids

Question 26

Prophase

Answer 26

Mitosis begins (nucleus begins to divide)
Centrioles (or poles) appear and begin to move to opposite ends of the cell.
Spindle Fibers form between the poles
nuclear membrane
nucleolus disappears

Question 27

Meatphase

Answer 27

Chromatids (or pairs of chromosomes) attach to the spindle fibers
Chromosomes are lined up along equator or middle of the cell. Double stranded

Question 28

Anaphase

Answer 28

Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell
divide or tear the centromere

Question 29

Telophase

Answer 29

Two new nuclei form (Double Yolk Egg)
Chromosomes appear as chromatin (threads rather than rods)
Mitosis ends

Question 29

Telophase

Answer 29

Two new nuclei form (Double Yolk Egg)
Chromosomes appear as chromatin (threads rather than rods)
Mitosis ends

Question 30

Cytokinesis

Answer 30

Cell membrane moves inward to create two daughter cells- each with its own nucleus with identical chromosomes.
