Question

5. In addition to water and carbon dioxide, photosynthesis requires
A. Light and chlorophyll
B. Oxygen and sugars
C. Sugars and light
D. Chlorophyll and oxygen

Answer 1

Thank you

Answer 2

I think you can definitely get this one.

What do plants need, in order to grow?

Try to remember elementary school.

Answer 3

sun light, water and co2

Answer 4

Yep! Light.

So, two of the answers have "light" in them.

It has to be either A or C, right?

Here, I'm gonna post a picture of photosynthesis.

Take a look at the picture.

You can see that water, carbon dioxide, and light energy are the REACTANTS.
That means that they go IN.
They are what's NEEDED, for photosynthesis.

And you can see that oxygen and sugar are the PRODUCTS.
That means that they come OUT of photosynthesis.
They are what is CREATED, from photosynthesis.

Answer 5

The picture won't tell you the answer,

but it WILL tell you which one is NOT the answer.

Answer 6

Thank you, it really helped a lot

Answer 7

You're welcome.

Answer 8

Your answer's A.

You knew that right?

Answer 9

yes,

Answer 10

Wonderful!

Answer 11

i am trying to understand what photosynthesis and cellular reparation is all about. That is i am an all-nighter

Answer 12

Oh yeah?

Photosynthesis is definitely a lot more simple.
It's basically how plants make their food (sugar).

Cellular respiration is something that I have yet to learn, too.

Answer 13

can you help me again if you are not busy?

Answer 14

ao i am watching this, thus man helped me a lot

Answer 16

this is about cellular reparation

Answer 17

You mean the video?

Answer 18

yes

Answer 19

Right. I see that it's about "anaerobic respiration."

That's respiration that doesn't need oxygen.

We're humans, so we definitely need oxygen.
We use a different kind of cellular respiration, called "aerobic respiration."

You know this?

Answer 20

ao, man before you even learn about it, you new what is right and wrong

Answer 21

Cellular respiration is actually a bit complicated.

But the basic equation for aerobic respiration is...

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + heat

The C6H12O6 is sugar.

The O2 is oxygen.

We need those 2 things.

The CO2 is carbon dioxide

and the H2O is water.

Those are the things that we produce, in aerobic respiration, along with heat.

When you breathe out of your mouth and nose, you are breathing out carbon dioxide, water, and heat.

Does that make sense?

Answer 22

thank you, man i wish i can give you another 3 medals but i can't. thank you

Answer 23

lol. Thanks anyway, and you're welcome.

Answer 24

I'll give you a medal for showing me the video,
and coming up with the right answer for photosynthesis.

Answer 25

Thank you, i just learned about the cellular recuperation

Answer 26

Cellular recuperation?

Answer 27

and thank you for being a good helper or teacher, you helped me how to get the answer
yes Cellular recuperation, how animals get their energy or ATP.

Answer 28

I've never heard of it called cellular recuperation before. Respiration, yeah.

But alright.

Answer 29

some people tell me the answer instead of telling me how to get the answer. you are a good helper

Answer 30

ao, sorry about the misspelling.

Answer 31

It's alright. I didn't know.

I'm glad you've learned more about cellular respiration though. Good luck with everything. I hope it goes well.

Answer 32

Thank you, its an ECR we have to wright today, about these things
