Plant Anatomy

1. Photo. What is this structure?
2. Photo. What is this structure?
3. Photo. This area shows the junction of three cell walls.  What is the thin line called that cements the cells together?
4. Photo. This Transmission Electron Micrograph shows a mesophyll cell (M) next to a bundle sheath cell (B) from a corn leaf.  Inside this organelle there are a series of stacked membranes.  What are they called?
5. Photo. This micrograph shows a cell that has been treated with antibodies to B-tubulin.  What are the structures that are brightly lit up?
6. Photo. This cell, stained with Ioidine Potassium Iodide, shows large ergastic substances.  What are they?
7. Photo. This cell is chuck full of clusters of long, needle-like structures.  What are they?
8. Photo. This is a cross section through the leaf of Ficus.  What is this structure that looks like a mace on a stalk?
9. Photo. This is a section through the seed endosperm of persimmon (Diospyros).  The cell walls are very thick and they serve a function that is unusual for cell walls.  What is that?
10. Photo. This hand section of a stem was stained with phloroglucinol.  Why are the fibers and xylem staining red?
11. Photo. This electron micrograph shows the surface of a plant cell wall with pores in this area that allow the plasmodesmata of adjacent cells to connect.  From the image, tell whether this is a primary wall or a secondary wall - and why.
12. Photo. This is a cross section of a Potamogeton leaf. What is the major cell type seen in the palisade and spongy mesophyll?
13. Photo. This is a section taken through the leaf of Nymphaea.  What is this tissue called with all the air spaces?
14. Photo. What are these pointy structures called?
15. Photo. This image was taken from the petiole of celery. What types of cells are shown here with thickened walls?
16. Photo. This is a section from a pear illuminated with fluorescent light.  What types of cells are these?
17. Photo. This is a cross section of the stem of a buttercup (Ranunculus).  What are these cells with thick, red-staining walls?
18. Photo. This is a hand section through the leaf of Peperomia.  What is this darker tissue layer called?
19. Photo. This is a peel made from the leaf of Pelargonium (geranium). What are these cells called that look like puzzle pieces? BE SPECIFIC
20. Photo. What are these cells called?
21. Photo. This is a section through an olive (Olea) leaf.  What is this layer here called?
22. Photo. These cells in the palisade mesophyll are full of chloroplasts.  Because of this, specifically what is the cell type?
23. Photo. The guard cells in this plant are bone-shaped (osteoform).  What family do these types of stomata occur?
24. Photo. This slide shows the surface of a leaf with stomata occurring in a row. The next slide hows the leaf and a stomata in section.  From the struture, is this plant a monocot, a dicot, or a gymnosperm?
25. Photo. This is a close-up view of the surface of Spanish moss (Tillandsia usneoides).  What are these structures and what is their function?
26. Photo. This is the water fern Salvinia. Specifically, what are these structures?
27. Photo. This is a L.S. of the stem of pumpkin (Cucurbita).  Specifically, what is the cell type for these cells?
28. Photo. What terms are used to describe the secondary wall thickenings?
29. Photo. In this slide of Sambucus you can see a progression of cell types.  Specifically, what is this type? Note the walls.
30. Photo. Is this image of a conifer or a dicot?
31. Photo. What is this structure?
32. Photo. Assuming the growth ring at the bottom represents year one, which was the worst year for this tree in terms of growing conditions?
33. Photo. The cell types above this point are called what and the cell types below called what.
34. Photo. The majority of cells shown in this image are what type of cell?
35. Photo. What type of section are we seeing here?
36. Photo. Specifically, what is this structure?
37. Photo. Specifically, what are these structures?
38. Photo. What type of section are we seeing here?
39. Photo. What are these square areas called?
40. Photo. Closer view of Sequoia wood, same region as previous. What type of pit is shown here?
41. Photo. What type of cell is this and does it have a primary or secondary wall?
42. Photo. This is a XS of Catalpa. What are these structures?
43. Photo. This is a XS of Catalpa. What term describes the distribution of these structures?
44. Photo. Specifically, what are these structures?
45. Photo. Specifically, what are these structures?
46. Photo. This is a section through Magnolia wood. Specifically, what are the majority of cells shown here?
47. Photo. This is a tangential section through Maclura wood. Specifically, what are cells shown here?
48. Photo. This is a radial section through Maclura wood. Specifically, what type of ray is shown here?
49. Photo. This is a tangential section of a ray, but something has happened to the ray parenchyma cells.  What happened?
50. Photo. This XS of Fraxinus (ash) wood has parenchyma cells in bands between the vessels. Is it apotracheal or paratracheal?
