- Cycad and Ginkgo
have motile sperm that swim.
- Pine
pollen is trapped by a droplet of liquid at entrance to a chamber which contains the megaspore.
- Gnetophyta:
(neeTOfita) Vessel-bearing gymnosperms
- Ephedra,
also called Ma huang: naturally derived from plants. Ephedrine chemically synthesized is regulated as a drug.
Promoted to aid weight loss, enhance sports performance, and increase energy.
On Dec. 30, 2003, FDA consumer alert.
February 2003 death of Baltimore Orioles pitcher Steve Bechler,
heart palpitations, tremors; stimulant, can raise blood pressure.
- Maple fruit: either Acer rubrum or negundo.
- Amborella is a basal angiosperm that lacks vessels found in more derived angiosperms (has only tracheids).
- Eudicots are “true” dicots, other dicots are basal angiosperms and magnoliids,
Magnoliids share primitive traits such as spiral arrangement of floral parts with the basal angiosperms.
- Acetylsalicylic acid -> aspirin.
