Cell Specialization 1 1 What does it mean

Cell Specialization (1. 1) What does it mean to be specialized?

Cell Specialization (3. 01) Cell # Ex. 1 2 3 4 5 6 Specia l Observations Function Name Location in the organism.

When you see each cell type, DO NOT name it (even if you know) Write observations about the STRUCTURE. Start with the example:

Functions. Start with the EXAMPLE. Does the structure match the function?

Match the following functions with each cell type based on their structure. Write the underlined portion. • Carry impulses from the brain all over the body. • Support and movement. Rigid. Strong due to layers. Offer protection for more delicate organs. • Carry oxygen to organs through blood vessels. • Used for movement. Created to flex and stretch over surfaces and to move bone. Contain LOTS of mitochondria for energy. • Store excess water and pump it out to prevent single celled organisms from exploding. • Move through blood vessels to seek out infection and invaders. They recognize them and destroy them.

Thinkables: Complete sentences. 1. Obviously the way a cell looks is different depending on the function. Do you think a cell will have differences in organelles depending on the function of that cell? Explain your answer. What organelle(s) would muscle cells need a lot of? 2. True/False: The nucleus of a cell contains different types of DNA depending on the structure and function of the cell for that organism. Explain your answer. 3. All cells have a phospholipid bilayer as a cell membrane. Thinking about the variety of shapes and sizes of cells what can you conclude about the cell membrane?

Cell Structures for Specialization • Flagellum- tail-like structure used for movement • Cilia- tiny hair-like structures used for movement • Microvilli- tiny hair-like structures used to increase absorption • Contractile vacuole- vacuole that pumps out excess water • Eyespot- structure used to locate sunlight for photosynthesis • phototaxis- movement towards sunlight • chemotaxis- movement towards a chemical
