What role does phosphorylation and dephosphorylation play in cell signaling? what role do secondary messengers, such as ca+2 and cyclic amp (camp), play in cell signaling? why are they called secondary messengers? what does cell signaling have to do with homeostasis of cells? how else, besides cell signaling, do cells do to maintain homeostasis? organisms respond to changes in their environment through behavior and physiological feedback mechanisms. give two specific examples of behavior mechanisms and the physiological response(s) of the organism(s).

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.
