Unlike a typical animal cell, this plant cell has an angular shape. the shape of a plant cell is due, mostly, to the presence of the
a. nucleus.
b. cell wall.
c. chloroplast.
d. cell membrane.

The right answer is cell wall.

The wall surrounds all the plant cells. It gives an angular aspect to the plant (pentameric, hexameric).

In terrestrial plants, the strongest component of the complex cell wall is a large carbohydrate called cellulose, while those of algae are usually composed of glycoproteins and polysaccharides. However, some species of algae may have a cell wall formed of silicic acid and the seaweed walls are characterized by sulphated polysaccharides which could play a role in the adaptation of the plant to the marine environment.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

the answer is: metamorphic rocks often show the presence of fossils, also a
