Golgi apparatus

a membrane-bound organelle in eukaryotic cells that modifies, sorts, and packages proteins and lipids for transport

Lysosomes

are membrane-bound cell organelles that act as the cell’s recycling and waste disposal center

Prokaryotic

Simple cells that do not have a nucleas and the DNA moves freely

Eukaryotic

Complex cells that have a nucleas and the DNA is stored there
