Warm Up 11/30 & 12/3/12• Copy objective:
– I will be able to examine specialized cells.– I will be able to identify the components of DNA.
Answer:• What is the difference between plant cells and animal
cells?
• Do all animal cells look like “this” animal cell? If not, how are they different?
• How are cells different from each other?
10-15 minutes

• From Last Class– Cell Energy Write to Learn– Cell Energy Mini Assessment– Exit Ticket
• From Today– Cell Specialization Activity– DNA Practice– Exit Ticket
5 minutes
Cell Specialization
• You will be looking at 10 pictures of different cells from plants an animals
• Make observations of the following compared to the “traditional” plant or animal cells:– Compare
• Shape • Organelles• Number of each
organelle
• Size

Cell Specialization Elbow Partners
Answer these questions with your elbow partner
• Why do you think they are all different?• Why is a nerve cell long?• Why is a blood cell flattened?• Why does the muscle cell have more
mitochondria?• What makes each cell different?• Do they have the same DNA?

• All living things contain DNA and RNA
• Building blocks of nucleic acids
• DNA = deoxyribonucleic acid
• it’s components are:
1. deoxyribose (sugar)
2. phosphate group
3. nitrogen base
• DNA Nitrogen Bases
1. adenine (A)
2. thymine (T)
3. cytosine (C)
4. guanine (G)
adenine ---thymineguanine --- cytosine

structure is a “double helix”
• DNA forms chromosomes• Chromosome are genetic material passed on
from parents to offspring
Notes Summary
• Write a 4 sentence summary about your DNA notes
5 min
Group Puzzle
• Step 1– Using your puzzle pieces find other students
and create a complete nucleotide
• Step 2– Now find a nitrogen base to pair with
• Step 3– Now find more nucleotides and create a DNA
section

DNA Practice
• Complete the DNA structure practice problems
10 min
Exit Ticket• Define these terms in your own words
– Cell differentiation– DNA– Nucleotide– Chromosomes
• What are the base pairings for DNA• Why are cells designed differently?
