Cell Membrane- Acts as barrier, not letting most molecules get into the cell.
Nucleus- Where the DNA is kept, and the RNA is transcribed. RNA is moved out of it through the nuclear pores, and the nucleus is referred to as the brain of the whole cell.
Nuclear Envelope- Separating the contents from the nucleus from the cytoplasm.
Nuclear Pore- RNA is moved through the nuclear pores to the rest of the cell.
Chromatin- The material of which the chromosomes of organisms other than bacteria.
Cytoplasm- All the contents outside the nucleus.
Mitochondrion- Main energy source of the cell, this is where the energy is created.
Golgi Complex- It processes and packages proteins inside of the cell.
Vacuole-Single membraned organelles of the cell.
Lysosome-Digestive system of the cell, breaks down molecules into digestive enzymes.
Ribosome-Found in the cytoplasm, this is where the RNA is transferred into proteins thorough a process called synthesis.
Endoplasmic Reticulum- Transport system for molecules.
