whena root is placed on its side, what happens to the amyloplasts in the root cap cells? a) they movey away from the direction of gravity b) they settle in the direction of gravity c) they move into the root apical meristem d) they are digested by amylase e) they move into a root hair

OpenStudy (anonymous):

@misssunshinexxoxo can you help me with that question ?

OpenStudy (phebe):

First to answer this you have to know what a amyloplasts is......... Do you know?

OpenStudy (anonymous):

amyloplast are used for starch storage in cells of roots and tubers .

OpenStudy (anonymous):

@Phebe

OpenStudy (phebe):

Yes, so if it is turned to the side what do you think will happen to the amyloplasts

OpenStudy (anonymous):

it is C right

OpenStudy (phebe):

Yes that is what i think

OpenStudy (phebe):

WELCOME TO OPENSTUDY!!

OpenStudy (anonymous):

im sorry, it is wrong. I choose C, my teacher marked it is wrong

OpenStudy (phebe):

okay so we can cancel C because thats wrong

OpenStudy (phebe):

We look at the other answer choices

OpenStudy (anonymous):

sure lolllll

OpenStudy (phebe):

LOL MMMHMMM

OpenStudy (phebe):

Amylase is a digestive enzyme that acts on starch in food, SO IT MIGHT BE D

OpenStudy (phebe):

YOUR ANSWER WILL BE OUT OF D AND E okay

OpenStudy (anonymous):

ok

OpenStudy (phebe):

which one you think it is

OpenStudy (anonymous):

I think a but i dont know how to explain

OpenStudy (phebe):

um.... yea you think A that actually wasnt what i thought the answer was but hold on let me read the question again

OpenStudy (phebe):

WAITT!!!!!!!!!!!!!!!!!!!!!!!! ik the answer now lol both of us was wrong

OpenStudy (phebe):

i should have read it better but your answer is B and i will explain it to you

OpenStudy (phebe):

Geotropism (also known as gravitropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Charles Darwin was one of the first to scientifically document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with any potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, growing (biologists say, turning; see tropism) upwards. Herbaceous (non-woody) stems are capable of a small degree of actual bending, but most of the redirected movement occurs as a consequence of root or stem growth in a new direction.

OpenStudy (phebe):

SO YOUR ANSWER IS B

OpenStudy (anonymous):

ok thank you so much

OpenStudy (anonymous):

can i ask you another question?

OpenStudy (anonymous):

Why dont the algae a group of organisms fixes nitrogen?

OpenStudy (phebe):

WELCOME!!! :D

OpenStudy (phebe):

hopefully this helps you

OpenStudy (phebe):

Wait re-put your question i think you typed it wrong ill help you

OpenStudy (anonymous):

the question is what group of organism fixes nitrogen? i answer the question is bacteria. my teacher wants me to explain why the algae did not the grup of that organism

OpenStudy (phebe):

so you want to know what group of organisms fixes nitrogen?

OpenStudy (phebe):

If thats your question your answer is Microorganisms

OpenStudy (anonymous):

I dont get it.

OpenStudy (anonymous):

they have a choose a) bacteria, b) algae, c) fungi, d) earthworms. At first, i choose b, but it is wrong, i find the right anwers is a, but i dont know how to explain why b is wrong

OpenStudy (phebe):

Microorganisms is bacteria

OpenStudy (phebe):

so................. let me explain it

OpenStudy (phebe):

Hopefully this helps Nitrogen fixation, natural and synthetic, is essential for all forms of life because nitrogen is required to biosynthesize basic building blocks of plants, animals and other life forms, e.g., nucleotides for DNA and RNA and amino acids for proteins. Therefore, nitrogen fixation is essential for agriculture and the manufacture of fertilizer. It is also an important process in the manufacture of explosives (e.g. gunpowder, dynamite, TNT, etc.). Nitrogen fixation occurs naturally in the air by means of lightning.[2][3] Biological nitrogen fixation can include conversion to nitrogen dioxide. All biological nitrogen fixation is done by way of nitrogenase metalo-enzymes which contain iron, molybdenum, or vanadium. Microorganisms that can fix nitrogen are prokaryotes (both bacteria and archaea, distributed throughout their respective kingdoms) called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosis) with diazotrophs.

OpenStudy (anonymous):

ok i got it thank you so much

OpenStudy (phebe):

WELCOME!! need anything else just pm me or tag me

OpenStudy (anonymous):

sure thank you

OpenStudy (phebe):

Oh by the way since I;ve helped you with this question you should close it
