WHAT ARE CELLS?9/29/11
Every living thing is made of cells!
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
What makes a cell?
3 things ALL cells have:• Cell membrane (barrier)• DNA (genetic info)• Cytoplasm (fluid)
Class Objectives: 1. Identify 3components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
Sketch both cells in your notebook.Label which is eukaryotic and prokaryotic.

in cytoplasm)

Important Ideas About Cells: (aka- the Cell Theory)
1. All living things are made of cells.
• Multicellular Organisms (many cells)
• Unicellular Organisms (one-celled)
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
2. 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.

3. New cells come from pre-existing cells.
A eukaryotic cell splits into two identical daughter cells by the process of mitosis.
Important Ideas About Cells: (aka- the Cell Theory)
A prokaryotic cell splits into two identical cells by the process of binary fission.

A DAY IN THE LIFE OF A CELLHow Cells Make and Use Proteins
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!]
