What is the function of the blue stained tissue of the celery?
The use of the stain toluidine blue provides
a colour difference between lignified and non-lignified cell walls
, clearly highlighting specialised cells and one adaptation they have. This experiment provides a quick and eye-catching way to teach about the vascular tissue in plants and the structure of plant stems.
Why does celery soak up food coloring?
When water moves into tiny spaces like that, we call it capillary action. In this activity the color in the water moved up into the celery with the water, because the
water molecules attached to the coloring
and brought it along.
Why do we cut celery under water?
When water moves through the stem, it
contains nutrients and minerals
the plant needs to survive. The movement of water allows various areas of the plant to receive these nutrients and minerals. In humans, capillary action is seen through blood vessels.
Why does celery wilt biology?
The salt in the water causes the celery to pull water out of itself to try and even out the salt to water concentration
. This causes the celery to wilt.
Does celery change food coloring?
The celery stalk in blue water in particular really soaked up the color.
You can see that even the stalk changed color
. To see the capillary action internally, trim the bottom of the stalks with a knife. You can see all the tubes that drew up water from the bottom of the stalk to the leaves.
What happens if you put celery in water?

You'll see the pale green leaves take on a reddish and bluish colour because the dissolved food colouring moves with the water through the xylem tubes into the celery stalk and leaves.
How do you keep celery fresh?

hypertonic to fresh water
