What is the purpose of boiling the leaf in water?
Have some canned spinach, which is boiled spinach leaves, tonight and find out.
What will happen to the boiling leaf when in ethanol what will happen to the leaf and the ethanol?
the ethanol will change colour and the leaf will soften
What happens when you put a leaf in boiling alcohol?
it turns green because the chlorophyll is evaporated out
Why does leaf turn light green when boiled in ethanol?
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
What is the function of starch in a leaf?
The function of starch in the leaf is to provide energy for the cell for the different functions. When the starch in the plant cells degrades, carbon is released so that it can be utilized in the production of sucrose.

why do we boil a leaf when testing phontosynthesis in a leaf?
to kill the cell which disrupt the cell membranes and softens the cuticle and cell walls
Do tree leaf cells have a cell wall?
Yes. All plant cells have a cellular wall, while animal and bacterial cells have cell membranes.
Does a leaf mesophyll cell have cell wall?
Yes. All plant cells have a cellular wall, while animal and bacterial cells have cell membranes.
How does having cells with cell walls help a leaf to absorb as much energy as possible?
Cell walls, unlike cell membranes, are not selectively permeable. Less energy would be able to leave the cells.
What is the texture of a leaf before boiling it in ethanol?
what type of leaf?
How goes having cells with walls help a leaf to absorb as much energy as possible?
Cell walls, unlike cell membranes, are not selectively permeable. Less energy would be able to leave the cells.
Why must the leaf be dipped in boiling water before immersing it in ethanol?
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.
What will happen to the boiling leaf when in ethanol what will happen to the leaf and the ethanol?
the ethanol will change colour and the leaf will soften
Does the Nucleus have a cheek cell or leaf cell?
The cheek cell has a nucleus and so does a leaf cell.
What does a leaf cell do?
The palisade leaf cell provides chlorophlly to the leaf as a result photosynthesis will take place in the palisade cell.
Why was the leaf placed in alcohol after being in boiling water?
The leaf was placed in alcohol wafter being placed in the boiling water to extract the green pigment from the leaf.
