Question

Help me check my work..

Answer 1

1. Which of the following is true? (1 point)Plants have adaptations that minimize light absorption.
Plants require less water on sunny days.
Most plants get the water they need from the soil.
Plants take carbon dioxide from the atmosphere and do not use oxygen.<----

Answer 2

@jhonyy9 @radar @Agent_Sniffles @ghazi

Answer 3

Plants actually do use oxygen, even though they also produce it.

Answer 4

So @InYourHead is this the right answer

Answer 5

can you help with this question
3. Which of the following is the most important process specific to land-dwelling plants? (1 point)production of photosynthetic pigments
conservation of water
exchange of gas
presence of cell walls

Answer 6

Your answer for #1 wasn't the right answer, no.

Answer 7

then what is it?

Answer 8

The choice that you picked says that plants "do not use oxygen."
And that's not true, because plants DO use oxygen.

Answer 9

is it A.

Answer 10

Have you read A?

Answer 11

You know, plants need sunlight, in order to stay alive.

To MINIMIZE would mean to REDUCE.

Answer 12

yes I have but none of the others sound right... It could also be c

Answer 13

I dont know all of these sound wrong to me

Answer 14

Well, we know that plants need MORE water, on sunny days.

So the second choice isn't true either.

Answer 15

Why does C sound wrong to you/

Answer 16

Because it doesnt seem that plants can get everything they need from the soil

Answer 17

My dear, plants get almost everything that they need from the soil. Water and nutrients included.

Answer 18

oh ok

Answer 19

The choice tells us that "most plants get the water that they need from the soil."

It's not talking about EVERYTHING.

Just water. You see?

And it's true.

Answer 20

what about this one
3. Which of the following is the most important process specific to land-dwelling plants? (1 point)production of photosynthetic pigments
conservation of water
exchange of gas
presence of cell walls

Answer 21

is it B?

Answer 22

There are two kinds of plants we can think of:

1. Land plants
2. Aquatic plants.

And yes, it is B.

Land plants don't live in the water.
So, in order to stay alive, they need to learn how to conserve (save) water.

Answer 23

and this one
What would have most likely occurred if plants had not begun to live on land?
Animals also would not live on land.
There would be no green algae in the oceans.
Animals would not undergo cellular respiration.
There would be no carbon dioxide in the atmosphere.

Answer 24

is it D.

Answer 25

Plants use carbon dioxide, in order to make oxygen.

If there were no plants, there would be a LOT of carbon dioxide,
because nothing would be using it.

Answer 26

B then?

Answer 27

Honestly though, I have to think about this question.

Answer 28

Why do you think it's B?

Answer 29

I have no idea!

Answer 30

You're just guessing one by one?

Answer 31

no.. I thought that was next logical guess

Answer 32

lol okay...what was your logic?

Answer 33

Honestly, I know next to nothing about algae, but I'm pretty sure algae has nothing to do with this question. We're talking about land plants here, not ocean plants.

Answer 34

Because plants come from the algae in the ocean?

Answer 35

They do?

Answer 36

I thought they came from seeds.

Answer 37

lol! I dont know!!

Answer 38

So now we believe it's either A or C.

Answer 39

I don't think A is true.

Because there ARE plenty of animals that don't live on land, as it is today.

~~~~~~~~

I'm leaning on C.

Cellular respiration is where we take food, and break it down, in order to make energy.

One of the steps of cellular respiration is called Glycolysis.
It breaks down sugars, in order to get energy.

~~~~~~~~~~

Here's the thing:
without land plants, there would be a lot less oxygen in the world.

But glycolysis can still happen, without oxygen.
We would just get a lot less energy from it.
We would call that "fermentation."

Answer 40

oh I see that makes sense

Answer 41

Makes sense to me too.

I just can't be 100% sure that it's the right answer. I wish I could.

Answer 42

Last one
What is a basic difference between a sporophyte and a gametophyte?
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 43

Could this be B

Answer 44

I'll tell you this one, because botany was so long ago for me.

It's not B, no. (Because the truth is the opposite)

It's actually C.
Remember this:

SPOROPHYTES are DIPLOID.
That means that they have the NORMAL amount of chromosomes, in each cell.

GAMETOPHYTES are HAPLOID. `
That means that they have HALF the amount of chromosomes, in each cell.

Answer 45

Oh! I think I might be able to remember that!

Answer 46

Yeah it's easy. We just have to repeat it to ourselves.

Sporophyte diploid.

gametophyte haploid.

Answer 47

Thanks!!

Answer 48

You're welcome.
