What organelles are apart of eukaryotic cells?

Plasma Membrane
Nucleus
Nucleur Membrane
Endoplasmic Reticulim (ER)
Golgi Apparatus
Mitochondria
Lysosome

Plasma membrane

contains enzymes to transport materials in and out of a cell.

Cell wall

Outer layer that provides protection from internal pressure and external forces.

Pili

Hair-like progections that allow bacteria to stick to one another and through which DNA can be exchanged.

Cytoplasm

Jelly-like fluid containing dissolved molecules and enzymes for metabolism. Most of the cell is cytoplasm.

Ribosomes

They are small organelles that make polypeptides (proteins) by joining amino acids together .

Nucleoid

Contains the genetic code (the information needed to make proteins, which are made by ribosomes).

Nucleus

The largest organelle It contains the DNA which controls heredity and all the activities of the cell.

Endoplasmic Reticulim (ER)

Protein synthesis, it can appear smooth or rough if many ribosomes attatch to it. - Synthesizes lipids and proteins.

Golgi Apparatus

Receives materials from the ER, modifies them and then sends them to other destinations.

Mitochondria

A medium sized and bean shaped organelle that performs cellular respiration to make ATP. It has an inner and outer membrane.

Lysosome

Small organelles that contain enzymes to digest macromolecules.
