The study of which structure was instrumental in the formulation of the modern cell theory?
plant cell
animal cell
cell membrane
dna molecule

The correct answer is molecule of DNA.

Explanation:

Based on the cell theory, all the living components are formed of one or more kinds of cells. All the living cells arise from the prevailing cells by the process of differentiation. The cell is the fundamental unit of composition and function in all living beings.  

Based on the novel version of the Cell theory, the energy flow conducts between the cells, all the cells possess similar chemical composition, and the DNA or the genetic information is passed on from one cell to another. Therefore, the study of the molecule of DNA played an essential function in the origination of modern cell theory.  

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.
