Have some canned spinach, which is boiled spinach leaves, tonight and find out.
The Leaf Will Stop all the processes it is doing and it will be so called "dead".
The boiling water kills the leaf, disrupts the cell membranes and softens the cuticle and cell walls.
what is the purpost of boiling leal in water
It removes the cuticle. The cuticle protects the leaf from dehydrating quickly.
the ethanol will change colour and the leaf will soften
boiling water
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour) wash with water to rehydrate and soften the leaf
The fear of boiling water refers to either getting burned by the steam, or the boiling water.
Boiling chips are not soluble in water.
The leaf was placed in alcohol wafter being placed in the boiling water to extract the green pigment from the leaf.
Is this question for real
The purpose of the waxy outer layer of a leaf, which is called a cuticle, is to keep the leaf from losing water inside the leaf. Plants that live in the water do not have this problem, so they have no cuticle.
what type of leaf?
Opening/closing of leaf pores (stoma) has the purpose to control evaporation.
A plant is destarched by placing a leaf under investigation in boiling water to get rid of all the excess starch. Then place into boiling ethanol to get rid of excess chlorophyll
Depending on the weight of the leaves, some will float to the top to give off their flavors to the boiling water, or will float to the bottom to accomplish the same task.
each vein contains xylem to bring water and minerals containing sap into the leaf and each leaf has phloem that carries sap of manufactured food ut of the leaf.
the ethanol will change colour and the leaf will soften
Raspberry leaf tea can be made by adding 1 tsp of the leaf to one cup of boiling water. The leaf should be infused for 10 min and then strained. The infusion can be taken once or twice a day.
boiling water
the green pigment, chlorophyll should be removed in order to observe color change during test for starch. in order to do that, the leaf is dipped in boiling water to break cell walls which would facilitate the release of the pigment out of the cell. immersion in ethanol would dissolve the pigment which would be released out of the cells thereby making the leaf appear pale in color.
