Which of the following is a correct description of guard cell activity with regard to stoma? - When the guard cells become flaccid from losing water, the stoma opens.

-Each stoma is controlled by a single guard cell, which absorbs water to open the stoma and loses water to close the stoma.

-The activity of guard cells in opening and closing each stoma helps maintain a state of balance in the leaf that maximizes photosynthesis and minimizes transpiration.

-When the guard cells become turgid with absorbed water, the stoma closes and CO2 cannot enter. ​

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.
