Cells, Cells, Cells!
Go back to your foldable, check if what
you wrote in the engagement is correct.
Make another foldable and write the
organelle, its structure, its function and
draw as we go on with the power point
presentation.

structure usually
located near the
center of the cell.
It is the control
center for all cell
activities.

and lets things in and
out of the cell
Made of Two Layers

CYTOPLASM
The cytoplasm is the
fluid of the cell, filling
the space between
organelles.
It provides space for
the cells to occupy
and move through.

MITOCHONDRIA
Bean-like structure
Have a smooth outer
membrane and a
folded inner
membrane
Makes ATP, which is
the energy of the cell

ENDOPLASMIC
RETICULUM
ER can be either
SMOOTH or ROUGH
Network of
passageways that
proteins travel through
Things travel from the
ER to the golgi
apparatus
![Page 12: Cells, Cells, Cells! - Johns Hopkins University](https://reader030.fdocuments.in/reader030/viewer/2022012011/613d5033736caf36b75bd8fb/html5/thumbnails/12.jpg)

GOLGI APPARATUS
Packaging Center
of the Cell
Modifies &
packages up
proteins before
they leave the cell
![Page 14: Cells, Cells, Cells! - Johns Hopkins University](https://reader030.fdocuments.in/reader030/viewer/2022012011/613d5033736caf36b75bd8fb/html5/thumbnails/14.jpg)

RIBOSOMES
Ribosomes make
proteins
Ribosomes are
found on rough ER
and in the
cytoplasm
![Page 16: Cells, Cells, Cells! - Johns Hopkins University](https://reader030.fdocuments.in/reader030/viewer/2022012011/613d5033736caf36b75bd8fb/html5/thumbnails/16.jpg)

VACUOLES
Large, round sac
found in the
cytoplasm
Stores water, food,
wastes, or other
materials needed
by the cell.

Summary
The cell is a system that is made of a
bunch of parts
Without each part working together, the
cell cannot function
These parts are called organelles, and
eukaryotic cells are full of them!
