A dichotomous key is a powerful tool for use in biology or any of the life sciences. It is also used in logic problems, physical sciences, and many other avenues. They are identified by having a choice of one of two options. Each selection will lead you to another pair of choices that ultimately leads to a final conclusion or organism identification.
They can be used in various fashions, from sorting playing cards
to identifying trees (while this is not a true dichotomous key – there are more than two choices for some of the steps – it helps show the branching process).
For more practice, try the following site:
If you have a tree that you are trying to identify, dichotomous keys are a good way to figure out what species you are dealing with. If you have a tree that you are trying to identify, try using the following dichotomous key from the OSU website:
This first two video clips go over the evolution of plants. While they are student videos, they do a pretty good job of outlining what we have discussed in class.
The final video looks at the role of plants for energy in our biosphere…
Start going over your notes, we will have a review on the 22nd and 23rd.
You will get your review packets on the 24th, but should start looking over your notes and plant evolution drawing…
Start reviewing your notes, assignments and warmups as our first test is coming up on Thursday, February 23rd!
This is a very rudimentary video, but it does a good job of getting the information across…It finishes with space rock information which is kind of cool.
The second video is not quite as childish, but still a little silly…
I feel pretty luck to have had this young lady twice, once in Biology and now in Botany. She is a great team player and asks good questions. She is always willing to work hard and shows interest in the subject. These traits combined with her effervescent personality will allow Alana to be successful as she continues through her high school years and beyond into her career of choice.
Just a quick video showing the opening of the sporangium in a sori for fern spores.
Here is a silly video, but it includes all of the parts of the fern life cycle.
