Answer:
Plant cells have a cell wall animal cells do not
Plant cells also have a permanent vacuole for food storage which animals do not
Only plant cells have chloroplasts as they use them to produce glucose
Because patches of thickened skin in the embryos created special cells known as columnar cells
The composition of the sucrose purified from sugar cane is
that both have the same composition of which both have produced. The
composition of sucrose purified from sugar beets has also the same composition
of which both produced and all produces sugar.
<u>Answer:</u>
<em>Light microscope, scanning electron microscopes and transmission electron microscopes have several similarities as well as differences.</em>
<u>Explanation:</u>
<em>1. Light microscopes</em> make use of visible light while scanning electron microscopes and transmission electron microscopes makes use of electrons. <em>Scanning electron microscopes use scattered electrons while transmission electron microscopes use electrons transmitted through the sample.
</em>
<em>2. Since electrons are used scanning electron microscopes</em> and transmission electron microscopes require vacuum for their working. Hence they cannot be used to analyze living samples. <em>Light microscopes doesn’t require vacuum for their working and hence can be used to study living samples.
</em>
<em>3. Scanning electron microscopes are used to observe the surface of specimen </em>while transmission electron microscopes are used to make a ‘through the’ specimen analysis. This makes the specimen preparation for each of the microscopes different. <em>Transmission electron microscope requires thin specimens while scanning electron microscope doesn’t practically require any specimen preparation.
