When cut carrots sticks begin to wilt they can be made firm again by placing them in water. Explain why.?

Answer 1

The contents of the cells of the carrot are hypertonic to water. So, if you put the carrot sticks into water, water moves by osmosis into the cells. The cells then expand, developing turgor pressure against the cell walls, making the carrot sticks crisp again.

Answer 2

Carrots are roots, which are made up of tiny tubes, called "vascular bundles (the whiter part in the middle) and a food and water storage area (the orange, softer part), along with other things.

Vascular bundles are made up of xylem and phloem, which carry food and water to the rest of the plant. When carrot sticks are placed in water, they "suck up" the water through their xylem, which then takes it to the cells throughout the rest of the plant (which, in this case, is just the rest of the carrot stick).

This causes the cells' cytoplasm to push out on their cell walls, making "turgor pressure." Turgor pressure is what causes plants to stand up instead of wilt, and the same thing happens in carrot sticks!

Answer 3

The same reason that household plants do when they begin to wilt. Carrots have a lot of water in them and wilting is a sign of drying out. Placing them in water helps to rejuvenate them.
