1 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

2 Needs to be turned into the box by end of day today 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

3 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 20 min

4 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? 10 min

5 Muscle cell

6 Red blood cells

7 Nerve Cell

8 Epithelia l cell

9 Wood Stem Cell

10 Stem Cross Section

11

12 Bone Cell

13 Skin Cells

14 Stem cells…

15 15 min

16 All living things contain DNA and RNA

17 Building blocks of nucleic acids

18 DNA = deoxyribonucleic acid its components are: 1. deoxyribose (sugar) 2. phosphate group 3. nitrogen base

19 DNA Nitrogen Bases 1. adenine (A) 2. thymine (T) 3. cytosine (C) 4. guanine (G)

20 adenine ---thymine guanine --- cytosine Apple-Tree Chewing-Gum

21 structure is a double helix

22 DNA forms chromosomes Chromosome are genetic material passed on from parents to offspring

23 Notes Summary Write a 4 sentence summary about your DNA notes 5 min

24 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 10 min

25 DNA Practice Complete the DNA structure practice problems 10 min

26 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? 10 min
