In imagining the evolution of ATP synthase as a key component of the chloroplast endosymbiont, describe when you think the key elements proposed in lecture and your book must have been working during the process of creating a functional endosymbiont. Were the evolution of the two kinds of proton pumps a necessary precondition? Give three other changes in the chloroplast that might have contributed to the productive symbiotic relationship between the host and the chloroplast.

hello which   of the following there is nothing!

the answer is c) abandoned properties that are contaminated with hazardous materials.

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.  

not too sure but maybe in the hot springs.
