How does the organelle structure affect its function

Endoplasmic reticulum is situated close to the nucleus and is involved in protein synthesis. Rough ER has lysosomes around the edges.

Lysosomes - The cleaner of the cell. Small and numerous, increases surface area and increases the rate at which waste products are removed from the cell.

Chloroplasts - Made up of Grana, stacked up to increase surface area. This allows more Chlorophyll to be made to increase the rate of photosynthesis.

Nucleus - Information point of the cell

It is evolution, because we all have some of the same traits like eye color or shape or ears.
