Question

Anyone?

Answer 1

5. What is a basic difference between a sporophyte and a gametophyte? (1 point)A sporophyte is a reproductive structure while a gametophyte is not.
A sporophyte undergoes sexual reproduction while a gametophyte undergoes asexual reproduction.
A sporophyte is part of the diploid phase while a gametophyte is part of the haploid phase of the plant life cycle.
A sporophyte is much smaller than the gametophyte.

Answer 2

@InYourHead

Answer 3

im going wth A

Answer 4

why A

Answer 5

I'm not leaning on A.

Answer 6

oh.. ok sorry.. lol :D

Answer 7

I took botany a few years ago. Give me a little time? I gotta research, and let the info come back to me.

Answer 8

k!

Answer 9

Okay.

I don't remember EVERYTHING I learned about plants.
But I think I've got enough information to help you with this question.

~~~~~~~~~~~

The GAMETOPHYTE and the SPOROPHYTE are two different phases, of the plant's life cycle.

The SPOROPHYTE phase is DIPLOID.
What that means is that is has the normal number of chromosomes, in each cell.

The GAMETOPHYTE phase is HAPLOID.
That means that it has only half the number of chromosomes, in each cell.

Answer 10

@InYourHead so is it C.

Answer 11

A sporophyte is part of the diploid phase while a gametophyte is part of the haploid phase of the plant life cycle.

Answer 12

Uh huh. I'm leaning on C.

Answer 13

oh man, alternation of generations

Answer 14

@aaronq what does that mean ^^^

Answer 15

alternation of generations is the cycling of sporophyte and gametophyte forms of the plant

Answer 16

of a plant*

Answer 17

@aaronq so you think its C. also right?

Answer 18

yep it's definitely C

i remember it because
gametophyte sounds like gamete which is haploid

Answer 19

oh cool way to think of it!

Answer 20

thanks alot!

Answer 21

no prob !

Answer 22

great job everyone! i just took the quiz, and it was C. Also i read over it all and the explanations of why it was C was really helpful! Great job and thanks a lot everyone!

Answer 23

1. Which of the following is true? (1 point)
(0 pts) Plants have adaptations that minimize light absorption.
(0 pts) Plants require less water on sunny days.
(1 pt) Most plants get the water they need from the soil.
(0 pts) Plants take carbon dioxide from the atmosphere and do not use oxygen.
1 /1 point
2. If plants need oxygen for cellular respiration, then why do plants release oxygen into the atmosphere?
(1 point)
(1 pt) More oxygen is produced during photosynthesis than the plant needs for cellular respiration, so
the plant needs to release the extra oxygen.
(0 pts) Plants need to collect more oxygen from the atmosphere because photosynthesis does not
produce enough oxygen to meet their needs.
(0 pts) Plants need to release oxygen into the atmosphere so more carbon dioxide can enter the plant
for photosynthesis.
(0 pts) Plants release oxygen into the atmosphere because the release of oxygen prevents the
evaporation of water.
1 /1 point
3. Which of the following is the most important process specific to land-dwelling plants? (1 point)
(0 pts) production of photosynthetic pigments
(1 pt) conservation of water
(0 pts) exchange of gas
(0 pts) presence of cell walls

Answer 24

4. What would have most likely occurred if plants had not begun to live on land? (1 point)
(1 pt) Animals also would not live on land.
(0 pts) There would be no green algae in the oceans.
(0 pts) Animals would not undergo cellular respiration.
(0 pts) There would be no carbon dioxide in the atmosphere.
1 /1 point
5. What is a basic difference between a sporophyte and a gametophyte? (1 point)
(0 pts) A sporophyte is a reproductive structure while a gametophyte is not.
(0 pts) A sporophyte undergoes sexual reproduction while a gametophyte undergoes asexual
reproduction.
(1 pt) A sporophyte is part of the diploid phase while a gametophyte is part of the haploid phase of the
plant life cycle.
(0 pts) A sporophyte is much smaller than the gametophyte.

Answer 25

100% correct! ^^^^
