13a. An embryo begins as a single cell. If each cell divides each day, then the number of cells will double each day. Every 10 days, the number of cells will be multiplied by 1000 = 10^3 every 10 days, approximately how many cells will there be after 20 days of cell division? 13.b Approximately how many cells will there be after 40 days of cel division?

Please explain how you got the answer.

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.  

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
