Question

Can you distinguish any cells?

are some cells larger than others


in an onion near the root tip can you see any cells in the process of cell division

Answer 1

What do you need help with?

Answer 2

those three questions

Answer 3

Those questions sound like they have something to do with something you saw in class (which we did not see). They are asking you what precisely you saw.

Answer 4

i do online schooling, they only provided me a worksheet

Answer 5

Was there a picture on the worksheet? It would be very strange to ask you "Can you distinguish any cells?" if it were impossible for you to distinguish any.

Answer 6

and a online link to draw some pictures

Answer 7

here ill try to attach the link

Answer 8

http://www.cellsalive.com/mitosis.htm

Answer 9

I don't think this is the right link. You just linked me to a video of mitosis. The question has to do with regular cells (presumably in an onion) and specifically the cells in the root tip.

Answer 10

thats the only link i was given and i had to draw the different phases and then those questions came up

Answer 11

Oh, ok... well... CAN you see any cells? The question is what YOU can see, not what I can see.

Answer 12

uhm im not sure its off of that link .

Answer 13

if this helps this is the worksheet http://curriculum.kcdistancelearning.com/courses/BIOx-HS-CA10/a/unit3/u3_labs/MitosisLabReport.rtf

Answer 14

Hrm, it really sounds like it was designed for an actual in-class activity... which, of course, doesn't work so well long-distance. Anyway, I googled for "onion root tip" and here's one of the pictures that I found: http://cache2.allpostersimages.com/p/LRG/27/2790/LTFOD00Z/poster/dennis-david-m-mitosis-in-onion-root-tip-cells.jpg

If you look at that picture, you should be able to answer those three questions at least.

Answer 15

so yes yes and what would be the last one im kinda confused

Answer 16

In the picture that I linked, the chromosomes are stained blue. Do you see any of them distinctly? Any distinct bundles of them that look like they might be pulling apart?

Here's another photo, by the way, showing more of the root tip. In this one, the genetic material is black: http://www.vcbio.science.ru.nl/public/Final-Images/PL_Final685z_051-100/PL0097_685zOnionRootTipOverview.jpg Again, look for distinct chromosomes that look like they're doing what you've seen in diagrams of mitosis.

Answer 17

so is the last one yes?

Answer 18

You tell me... what do you see? :)

Answer 19

im thinking yes

Answer 20

Yep! And here's yet another picture of an onion root tip where the phases are even labelled: http://schoolworkhelper.net/wp-content/uploads/2011/02/onion-mitosis-3-lab.jpg

Now... do you know WHY there's so much mitosis going on in the root tip?

Answer 21

kinda

Answer 22

Kinda?

Answer 23

i just dont understand bio alot

Answer 24

can oyu help me with the second page of the worksheet

Answer 25

Don't worry about it. 90% of biology is just facts, and with time, you'll learn them.

Answer 26

The problem with this worksheet is that it's talking about something that you should be able to see. Are you SURE there are no images associated with it? I mean... it's even asking you to count the number of cells, and that's not possible without knowing what you're supposed to be looking at.

Answer 27

i have no idea .

Answer 28

Is there a teacher you can email?

Answer 29

no.

Answer 30

its all independent

Answer 31

Well, find out who's responsible for this worksheet and email them. It's possible they just screwed up and forgot to upload the image(s) associated with it.

Answer 32

thats not really possible to contact anyone

Answer 33

What kind of distance learning thing is it if there's no way to contact anyone?

Answer 34

Maybe ask your mum or dad for help. In the meantime, I'd advise reading a bit more about mitosis, looking at diagrams, and thinking about why there's so much of it in the root tip.

Answer 35

can you help me with someting else
