Plant Pollination and Reproduction

Don’t forget to finish your pollination readings/coloring packets. It is important that you understand how the flowers reflect the organism/wind that pollinates them.

This first video looks at plant pollination:

This next video includes a look at an unusual example with milkweed…

This video looks at bee orchids and pollination…

The last two videos are in more detail than you need to know, but look at angiosperm and gymnosperm reproduction.

Plant Transport

Here is a video reviewing the process of plant transport…

Make sure you know the three forces that allow plants to move water through the plant:

    Root Pressure (including Osmosis)

    Capillary Action

    Transpiration

Typically this goes from root to leaf.


Nutrient flow (sugars) typically flow from leaves to roots. Gravity helps out here and the phloem moves materials from where they are made to areas of storage (called sinks).


In both cases materials are moving from HIGH concentration to LOW concentration (remember your concepts of diffusion)

Specialized Tissues in Plants

The following videos do a good job outlining the different structures of the plant. The young man who is going over the structure pronounces structures very differently in some cases from what we have been using in class. Knowing all of the tissues will help you understand how they perform their specific functions. Tissues of note include: vascular tissue, dermal tissue, ground tissue, and meristematic tissue.

Botany: Final Project

The final project allows students to customize their learning to meet their interests. Students will have several options in terms of work product and presentation of the material. Options include:

Work Product
• Botany Phyla Project (Phyla Project Guide)
• Research Paper (Research Paper Guide)
• Botany Experiment (Experiment Paper Guide)
• Botany Video/Radio Program (Script Guidelines; Video Guide)
• Design-a-Garden (& implementation) (Design-A-Garden Guidelines – draft – Don’t forget to check your hardiness zone: Hardiness Zone Map)

In all cases, the project will cover an instructor approved topic. You are able (and encouraged) to work in partners, BUT…I will expect twice as much work! We will have some time to work on assembling your results and presentation for the class, but the majority of work will be done OUTSIDE of class.

Before sitting down to write you must have ideas, a plan in mind and genuine understanding to communicate. That comes from reading everything you can get your hands on related to your subject. How much? Well, I’d feel a bit insecure writing about anything until I’d digested and understood anywhere from one to two dozen solid references. I’d probably have looked at or skimmed 50 to 100, but not all of them would end up specifically referenced. Many have no relevant material, or nothing unique, not found in the other references. Some are useful only to lead to better sources. Everyone should take a look at these helpful tips for writing in science:

Tips for Writing in Science

If you want to be on pace to have a quality project completed for the turn in date the following guidelines should be met:

Research Notes Collected By: April 29th
Rough Draft: May 22nd
THE FINAL PAPER IS DUE JUNE 2ND – NO MATTER WHAT!!!

Presentation Dates will be assigned as we get closer.
