I did my blog post about tomato cells. Tomato cells start out with large amounts of a green pigment called chlorophyll (inside of chloroplasts) when it first starts to grow. This explains why tomatoes start out as a green color. There are tons of cells inside tomato skin. They seem to be a lot more of a circular shape which is different from the onion cells which are more like a brick shape. When tomatoes get older/riper other pigments like lycopene start showing up. Lycopene is the reason why a tomato becomes red. Lycopene is like a stain for the outside cover of the tomato. It makes all red fruits and vegetables red. Lycopene begins to dominate other chlorophyll pigments and that is why tomatoes become such a red color. I think that it's interesting how the tomato cells change color.
I got my Information from this link: click here.
This is a comparison between onion and tomato cells.

Those pictures are very clear, the onion cell looks like it's fake! In the tomato cells, are those black things splotches or the nucleus in the tomato cell?
ReplyDeleteGreat post! Do you know why the tomato cells are rounder then the onion cells?
ReplyDeleteYour pictures are very clear!
ReplyDeleteDo you know what a chromoplast is? Look it up and see what you discover. ;)
ReplyDeleteVery interesting, do you know why there round
ReplyDeleteThis is really cool! Do you know why the tomato cells are circular and the onion cells are squarish?
ReplyDeleteHow did you get the chance to look at tomato cells? Our class didn't...
ReplyDeleteReally cool pictures!! I think it's cool that you chose a whole new cell to work on!!!!
ReplyDeleteWas the tomato cell pic under lower light?
ReplyDeleteNice but could you explain why the shapes of the cells were different?
ReplyDeleteThis is awesome Liam! Like everyone else I'm wondering why the tomato cell is circular?!
ReplyDeleteThat's cool that you got to do tomato cells. Why is the cell round though?
ReplyDeleteIt was a good idea to compare it with an onion cell! But can you explain why the tomato cells are round? Also why do they gain lycopene as they get older?
