Question

Which of these is NOT true of cells?
A.They are much like empty rooms.
B. They were first discovered in the 1600s.
C. They can be found in pond water.
D. They contain a huge array of working parts.

Answer 1

What would you guess?

Answer 2

B

Answer 3

Cells contain a lot of organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, vacuole, nucleus, peroxisomes and so on... with this in mind what would guess then?

Answer 4

A

Answer 5

Correct. :)

Answer 6

thank you

Answer 7

No problem.

Answer 8

Which of the following statements about the nucleus is NOT true?
A. The nucleus stores the coded instructions for making the cell’s proteins.
B. The nucleus usually contains a nucleolus region which is where ribosome assembly begins.
C. The nucleus is the site of protein assembly.
D. The nucleus is surrounded by a nuclear envelope that lets materials in and out.

Answer 9

Again take a guess, if wrong I give a hint.

Answer 10

C

Answer 11

Correct. :)

Answer 12

WOW im better than I thought

Answer 13

Which structure in the cell shown in Figure 7–2 stores materials, such as water, salts, proteins, and carbohydrates

Answer 14

Never underestimate your self :)
And if you are in doubt, then answer the first idea that come to your mind, in many cases it is the right answer.

Answer 15

During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will
A. move across the membrane to the outside of the cell.
B. stop moving across the membrane.
C. continue to move across the membrane in both directions.
D. move across the membrane to the inside of the cell.

Answer 16

Again take a guess :)

Answer 17

A

Answer 18

Diffusion is a potential (a chemical potential) that is able to equalize concentration differences, and go from high concentration to low concentration, when the concentration of both sides is the same the net diffusion equals 0.

Answer 19

so its C ?

Answer 20

Sure is :)

Answer 21

Compared to small cells, large cells have more trouble
A. dividing.
B. producing daughter cells.
C. storing needed materials and waste products.
D moving needed materials in and waste products out.

Answer 22

Think about the surface-area-to-volume ratio.

Answer 23

is it A ?

Answer 24

Nope, it is related to the last question.

Answer 25

C ?

Answer 26

D :)

Answer 27

hows it D ?

Answer 28

Which of the following is NOT true?
A. ATP is only formed during aerobic respiration.
B.ATP contains less potential energy than ADP.
C. Plant cells generate ATP during cellular respiration.
D. ATP is used as a mobile energy carrier molecule by all cells

Answer 29

Small cells have a high surface-area-to-volume ratio that makes them able to diffuse different molecules in or out more easy than big ones. The higher the surface-area-to-volume ratio the better diffusion can happen in a cell.

Answer 30

im guessin C

Answer 31

Have you heard about fermentation?

Answer 32

no

Answer 33

Hmmm... okay can tell you the answer is A. ATP is also produced during anaerobic respiration.
A plant can also do cellular respiration.

Answer 34

It makes a very small amount of ATP in photosynthesis but it use that again during the Calvin cycle (uses 6 ATP) for 1 run.

Answer 35

The light-independent reactions of photosynthesis
A cannot occur if the light-dependent reactions are briefly inhibited.
B involve the formation of carbon-carbon bonds.
C only occur in the dark.
D produce carbon dioxide and water.

Answer 36

The light-independent reaction is the Calvin cycle. So if you know the calvin cycle you have the answer.

Answer 37

"Which of the following is NOT true?
A. ATP is only formed during aerobic respiration.
B.ATP contains less potential energy than ADP.
C. Plant cells generate ATP during cellular respiration.
D. ATP is used as a mobile energy carrier molecule by all cells
"

Correction: I said some rubbish, the obvious answer is B, but A is also true. but take B if you can!
