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

• nucleus

• chloroplast

• cell membrane

The main difference between a prokaryotic cell and a eukaryotic cell is

• the ability to grow.

• the ability to reproduce.

• the presence of nucleic acids.

• the presence of a true nucleus.

This organelle is found in plant cells. The function of this organelle is to collect solar energy and use this to produce food, or glucose, for the plant. This organelle is the
