In many ways, the eukaryotic cell is kind of like a city. I will tell you what each of the organelles in a cell does. Your job will be to try to match each of the cell parts to the parts of a city and explain why they are similar.
a) Golgi Apparatus: packages up proteins and labels them for distribution to other parts of the cell.
b) Vacuole: a container for liquids, food, waste, or other materials. Large in plants, smaller or absent in animal cells.
c) Chloroplast: uses light energy and CO2 (carbon dioxide) from the air to build long chains of carbons (sugars and starches), releasing O2 (oxygen) along the way.
d) Lysosome: a place where waste products and cellular debris are broken down.
e) Mitochondrion: burns food to create ATP, an energy storage molecule which can be used by the whole cell.
f) Nucleus: contains DNA, the instructions for building and operating the cell.
g) Cell Membrane: regulates what enters and leaves the cell.
h) Endoplasmic Reticulum: a network for transporting proteins across the cell.
i) Ribosome: reads the messenger RNA, copied from the DNA instructions in the nucleus, and is the site where proteins are made. Ribosomes are made in the nucleolus.
j) Cell Wall: in plant cells, a tough wall outside the cell membrane that provides protection and structural rigidity, made of cellulose.
