4 Main Macromolecules Found in the Cell

Plasma Membrane-
Controls what enters
and leaves the cell

Nuclear Envelope-
Surrounds Nucleus
in double membrane

Ribosomes-
Digests enzymes such as Lipids

Endoplasmic Reticulum-
Site of Lipid synthesis

Nucleolus-
Site of ribosome production

Mitochondria-
Converts energy
into ATP
(usable energy)

Cell Wall-
Supports and protects
the plant cell

Cytoskeleton-
Supporting network
of long thin protein fibers

Ribosomes-
Help manufacture
proteins

Endoplasmic Reticulum-
Site of Protein synthesis

Golgi apparatus-
modifies, sorts, and packages proteins
into sacs called vesicles

Nucleus-
Stores information
to make proteins

Nucleolus- Controls Nuclelus

Nucleus- Contains most of the cells DNA

Chloroplasts- Captures light energy and converts it into energy usable by the cell
