Science 4

Question 0

What happens during prophase of mitosis?

Answer 0

The spindle fibers form and the centrioles moves to opposite sides of the cell. The nuclear membrane disappears.

Question 1

Name the four phases of mitosis.

Answer 1

Prophase, metaphase, anaphase, telophase

Question 2

What happens during metaphase?

Answer 2

The chromosomes align midway along the spindle fibers.

Question 3

What happens during anaphase of mitosis?

Answer 3

The chromosomes begin to separate from their daughters. Cytokinesis begins.

Question 4

What happens during telophase of mitosis?

Answer 4

Identical sets of chromosomes are at opposite ends of the cell. Spindle fibers disappear, nuclear membranes reappear, and cytokinesis completes.

Question 5

Name the eight phases of meiosis.

Answer 5

Prophase one, metaphase one, anaphase one, telophase one, prophase two, metaphase two, anaphase two, telophase two

Question 6

In meiosis, what happens during prophase one?

Answer 6

Homologous chromosomes condense and link in the process forming tetrads. This allows crossing over or recombination to occur.

Question 7

And meiosis, what occurs during metaphase 1?

Answer 7

Homologous chromosomes move to the metaphase plate.

Question 8

In meiosis, what happens during anaphase 1?

Answer 8

Homologous chromosomes separate, but the sister chromatids stay together.

Question 9

In my meiosis, what occurs in telophase 1?

Answer 9

Cytokinesis has occurred and two haploid daughter cells are the result.

Question 10

In meiosis, what occurs during prophase two?

Answer 10

A brief stage in which spindle fibers begin to reappear and centrioles move to opposite poles.

Question 11

In meiosis, what occurs during metaphase 2?

Answer 11

Sister chromatids align at a new metaphase plate.

Question 12

During meiosis, what occurs during anaphase two?

Answer 12

Sister chromatids separate again.

Question 13

During meiosis, what occurs during telophase two?

Answer 13

Four haploid cells results after cytokinesis.

Question 14

During meiosis, a _______ cell will give rise to four ______ cells.

Answer 14

Diploidy, haploid

Question 15

True or false. Mitosis and meiosis occur in all types of cells.

Answer 15

False. Mitosis occurs to replace old cells in the all cell types, while meiosis occurs in gametes to bring about genetic variation amongst offspring.

Question 16

What two processes result in the formation of cellular energy for an organism?

Answer 16

Photosynthesis and cellular respiration

Question 17

What organisms carry out the process of photosynthesis?

Answer 17

Green plants, green algae, and certain bacteria

Question 18

What happens during photosynthesis?

Answer 18

Energy from sunlight is trapped by chlorophyll and used to make glucose

Question 19

What organelle allows sunlight to be trapped by chlorophyll?

Answer 19

Chloroplast

Question 20

What three things contained in chloroplast is used to produce ATP?

Answer 20

Carbon dioxide, water, and energy from the sun

Question 21

What is ATP considered to be?

Answer 21

Cellular fuel

Question 22

What does the cellular fuel ATP provide the energy to accomplish?

Answer 22

Produce glucose from carbon dioxide and water liberating oxygen in the process

Question 23

What do you call an organism that is able to produce its own food?

Answer 23

Autotrophs

Question 24

What do you most out of autotrophs use to live?

Answer 24

Photosynthesis

Question 25

What is the chemical equation for photosynthesis?

Answer 25

6CO2 + 6H2O + energy= C6H12O6 + 6O2 | Carbon dioxide + water + sunlight = glucose + oxygen

Question 26

What is the formula for glucose?

Answer 26

C6H1206

Question 27

During cellular respiration what is used to produce ATP for cells?

Answer 27

Glucose

Question 28

What are organisms called that cannot produce their own food?

Answer 28

Heterotrophs

Question 29

What process does heterotrophs use to produce cellular energy?

Answer 29

Cellular respiration

Question 30

During cellular respiration how is glucose broken down?

Answer 30

By the process of glycolysis

Question 31

What happens during the process of glycolysis?

Answer 31

Some of the energy from glucose is transferred to ATP

Question 32

What is another name for the citric acid cycle?

Answer 32

Krebs cycle

Question 33

What two cycles constitute cellular respiration?

Answer 33

Glycolysis and the Krebs cycle

Question 34

What do cells use to carry out glycolysis and the citric acid cycle?

Answer 34

Mitochondria

Question 35

During glycolysis and the Krebs cycle what happens to oxygen, water, and carbon dioxide?

Answer 35

Oxygen is used up while both water and carbon dioxide are formed as a byproduct

Question 36

What happens to the carbon dioxide that is formed as a byproduct from glycolysis and the citric acid cycle?

Answer 36

It is expelled but can be used by autotrophs during photosynthesis

Question 37

What is the chemical equation for cellular respiration?

Answer 37

C6H1206+602 yields 6CO2 + 6H2O + energy | Glucose + oxygen = carbon dioxide + water + energy

Question 38

A new type of algae has been discovered. To determine whether or not this allergy is an autotroph, the scientist should observe for which of the following? Chloroplast, mitochondria, glucose, or ATP.

Answer 38

Chloroplast

The organelle implants that allows photosynthesis to occur is the ______, which contains the chemical ______ to trap energy from the sun.

Answer 39

Chloroplast, chlorophyll
