Happy Wednesday Buffs!
Bellwork: Name at least two things Prokayotes and Eukaryotes have in common and at least two things that make them different.

Projects…
Are due one week from today.
After today you should have a good idea about what you want to do and should be making plans to get started.

There are many theories about how the first Eukaryotes emerged.
The Endosymbiotic Theory is the most widely accepted
The Endosymbiotic Theory states that the organelles of eukaryotes originated as a symbiosis between separate single-celled prokaryotes.

Break it down…. Endo = inside Symbiosis = a beneficial relationship

Explains how organelles were most likely formed
Also explains why organelles are membrane-bound

Cell Organelles and their Functions
Page 11:Essential question:What are the organelles in a cell and what do they do?

Cells Cells are the basic unit of all living things.
IF IT IS ALIVE, IT HAS CELLS!
Cell Theory: All organisms are made up of one or more cells
The cell is the basic unit of all organisms
all cells come from cells

E. Endoplasmic Reticulum A network of membranes throughout the
cytoplasm of the cell. It helps to move materials around the cell Can be smooth or rough.

F. Golgi apparatusResponsible for sorting, packaging, and
shipping the proteins produced in the ER.

G. Ribosomeshelp in the synthesis of proteins.Some ribosomes are found in the
cytoplasm, but most are attached to the endoplasmic reticulum.
