6. Important Ideas About Cells: (aka- the Cell Theory)
1. All living things are made of cells.
Unicellular Organisms (one-celled)
Multicellular Organisms (many cells)
Class Objectives:
Identify 3 components that ALL cells have
Explain why cells are important to All living things
Explain where the heck cells come from

7. Important Ideas About Cells: (aka- the Cell Theory)
Cells give an organism its structure and function - they control everything the organism needs to do to stay alive
Even the most complex organisms are made of
a bunch of different types
of cells working together.
Class Objectives:
Identify 3 components that ALL cells have
Explain why cells are important to All living things
Explain where the heck cells come from

8. Important Ideas About Cells: (aka- the Cell Theory)
New cells come from pre-existing cells.
A prokaryotic cell splits into two identical cells by the process of binary fission.
A eukaryotic cell splits into two identical daughter cells by the process of mitosis.
Class Objectives:
Identify 3 components that ALL cells have
Explain why cells are important to All living things
Explain where the heck cells come from

11. A day in the life of a cell
How Cells Make and Use Proteins

12. Put this in your notebook:
Proteins – Large molecules that do many important jobs in living things, such as:
Form body structures (muscle, bone, hair, eyes, nails, skin)
Act as enzymes to speed up chemical reactions (like digestion) in our bodies
Act as hormones that send signals through the bloodstream
[And many other things we’ll learn about later!]
Class Objectives:
Describe 3 things that proteins do for the body

13. Proteins A Day in the Life of The Cell
Proteins are large molecules that do many important jobs in living things, such as:
Form body structures (muscle, bone, hair, nails, skin)
Act as enzymes to speed up chemical reactions (like digestion) in our bodies
Act as hormones that send signals through the bloodstream
[And many other things we’ll learn about later!]

14. Cytoplasm RNA Nucleus E.R. ATP energy A Day in the Life of The Cell
Released into blood stream and used as hormone
Protein
Ribosome
RNA
Golgi Apparatus
(Modifies and shapes the protein)
Protein being formed at Ribosome
Nucleus
Cytoplasm
Protein could go to membrane to be released into blood stream
DNA
(Holds genetic information)
RNA
(Copies info from DNA and carries it to the Ribosome to make proteins)
Or the protein could go to a lysosome to be a digestive enzyme
Vesicle
(“bubble” that transports proteins)
(transports and packages proteins)
E.R.
Lysosome
::Blood Stream::
Cell Membrane
Food or waste particle
CO2 + H2O
ATP energy
(for the cell to use)
Ribosomes
Mitochondria
Cell Respiration
