Plants have openings on their leaves called stomata, through which gases, including water vapor, can pass in and out of the plant. Plants open and close stomata in order to regulate the exchange of gases with the atmosphere. Why might it
benefit plants to keep their stomata closed under certain conditions?

To decrease the need for nutrients

To reduce water loss during a drought

To increase energy production at night

To prevent predation of insects

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.
