How would you test the presence of starch in leaves?

1. Remove a green leaf from the plant

2. Boil the leaf in boiling water stop enzymatic reaction within cells in leaf

3. Put the boiled leaf in boiling tube containing alcohol extract (ethanol) chlorophyll ethanol dissolves Lipids in cell membranes.

4. Return to leave to the hot water soften the leaf and allows penetration of iodine

5. Remove leaf and perform the iodine test

Explanation:

starch is white powdery substance consisting of glucose which is used by plants as food the percents of starch in leaves evidence enough of the process a photosynthesis being carried out in leaves as the formation of starch necessitates photosynthesis.

I hope this helps :)

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
