What part of the heart receives oxygen rich blood from the lungs and squeezes it into the right ventricle?

This is the part of the heart on the left side of the heart that receives oxygen-rich blood from the pulmonary vein that is responsible for then moving the blood into the left ventricle. It is relaxed with blood and contracted without any blood present.

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.
