Sophia is testing an effect of different volumes of water on the growth of duckweed. she set up the experiment that is shown below. three beakers, all the same size, are set up with cool tap water and duckweed in them. the first beaker contains 100 ml of water and 20 fronds of duckweed. the second beaker contains 200 ml of water and 50 fronds of duckweed. the third beaker contains 300 ml of water and 40 fronds of duckweed..

based on this setup, the most likely source of error in this experiment is
a)the sizes of the beakers that are used.
b)the depth of the water in each beaker.
c)the temperature of the water in each beaker.
d)the number of duckweed plants in each beaker.

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.
