Download Day 8: Organelles and what they do

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

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

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

A. Cell Membrane:
 holds
the cell together and allows
nutrients into the cell.
A
B. Cytoplasm
 the
 It
watery gel inside a cell.
holds the ORGANelles.
B
C. Mitochondria
 ORGANelle that produces energy
for the cell.
C
D. Nucleus
 The
nucleus controls the cell.
 It contains the cell’s DNA.
D
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.
E
F. Golgi apparatus
 Responsible
for sorting, packaging, and
shipping the proteins produced in the ER.
F
G. Ribosomes
 help
in the synthesis of proteins.
 Some ribosomes are found in the
cytoplasm, but most are attached to the
endoplasmic reticulum.
G
H. Vacuoles
 Vacuoles
are spaces in the
cytoplasm where food and
chemicals are stored
H
I. Cell Wall
 Cell
Walls are in plant cells and
bacteria
 They
I
make the cell strong and rigid
J. Flagella
 Can
be found in both prokaryotic
and eukaryotic cells
J
 Used for movement
