3. LEAF TISSUE (cross section)

Is there a cell membrane? A cell wall? Note the green pigment inthe chloroplasts. Is green color found outside of chloroplasts?Why?

4. GIANT MULTIPOLAR NEURON

Look for the long fibers that support the processes. Whatcytoskeletal components are these composed of? Can you suggest afunction for this characteristic?

5.SPERM (frog)

How do this structure and size relate to the function of asperm?

6. ADIPOSE TISSUE

Look for cell boundaries and nuclei in the cytoplasmic areas.Can you suggest a function of these fat cells?

7.EPITHELIUM (columnar)

What is the internal structure of microvilli? What is theirfunction?
