Botany 10 Work Blog

Exercise 1 The first exercise did not go as expected. The blue dye barely moved up the celery stalk if at all. Dye table: When the dye was seen there was barely any progress. Here is a picture of the base of one of the stalks stripped down to show the lack of blue dye.  (The stalk was cut shorter as well to make sure I got a better picture of it) The start for every stalk. Here are some of the pictures of the base of the stalks (Again, some cut down shorter after the initial soak to check deeper inside) Exercise 2 This exercise was to examine the independence of water transport up different vascular bundles in celery. At this point, I thought that I must have done something wrong if I was getting such a strange result, but I decided to continue and finish the lab, instead of immediately restarting to get the result I wanted. Here is a picture of the stalk in the two different dyes.     Here you can see the red side of the stalk after it had been pulled apart. You can...

 Update to the bean plant You can see here that the trifoliate leaves have formed, and one of the branches actually broke itself with its own weight. These will now be replanted outside with better support.

  The ranking from most to least time in a stage goes: Interphase, Prophase, Metaphase, Anaphase, Telophase. In the Interphase the whole cell and the nucleus are visible. In the prophase the cell wall and the insides are visible. In the Metaphase the chromosomes are visible. In the Anaphase they begin to separate. In the Telophase you can see the two cells separately.

LAB - Part 5, Twigs   The terminal bud on this plant is very clear and noticeably different from some of the surrounding plants. The terminal bud scale scars are also quite noticeable and you can see that closer to the root the growth between them is quite large compared to the growth later on.

LAB - Part 4, Describing Leaves Leaf A: Leaf Arrangement: Alternate Leaf Margin: Crenate Leaf Venation: Pinnate Surface Description: Smooth Leaf B: Leaf Arrangement: Whorled Leaf Margin: Entire Leaf Venation: Unkown Surface Description: Smooth/Porous  Leaf C: Leaf Arrangement: Whorled Leaf Margin: Entire Leaf Venation: Parallel/Unkown Surface Description: Smooth/Speckled  Leaf D: Leaf Arrangement: Whorled Leaf Margin: Serrate Leaf Venation: Pinnate Surface Description: Furry/Silky Leaf E: Leaf Arrangement: Alternate Leaf Margin: Serrate Leaf Venation: Pinnate Surface Description: Damp/fragile Leaf F: Leaf Arrangement: Alternate Leaf Margin: Entire Leaf Venation: Pinnate Surface Description: Leathery

 LAB - Part 3, Mature Plants Branch A labeled with anatomy                                                                            Branch B labeled with anatomy Both plants were found in my backyard and show almost all the key features of anatomy. We can see evidence of branching from the axillary buds on both branches located on the Axillary Bud label. The leaves on branch B are alternate while the leaves on branch A seem to be whorled. The leaves in branch A had a palmate venation and the leaves in branch B had a pinnate venation. The leaves on branch A had a serrated edge while the leaves in B had crenated edges.
