here's three:
-pine tree
-dugles fir tree
-redwood tree
it said that have about 800 types, Cupressaceae,Pinaceae,Taxodiaceae,Ephedraceae... right?
The four types are Cycads, Conifers, Gingko and Gnetophytes
angiosperms i think but im not positive
At this level of taxonomy, there are gymnosperms and angiosperms. The gymnosperms have 'naked seed'. (Hence the gymno part of the name)The angiosperms have an ovary for producing seed, in conjunction with pollen.Earlier taxonomy has the ferns, mosses, and the non-vascular plants, seaweeds, and in New Zealand we have a a few species of Tmesipteris. These early plants do not have flowers, but the ferns at least have sexual reproduction.
Coniferophyta of Gymnosperms
chesse
olive
Gymnosperms are seed-producing plants that include conifers, cycads, and gingko.
Gymnosperms produce "naked" seeds are they are not held in an ovary (like Angiosperms), but are produced in cones
cycades
angiosperms -seeds in think protective layer and gymnosperms- seeds directly on cones
Nonvascular plants Ferns Gymnosperms Flowering Plants
Gymnosperms pollination occurs after the micro spores are released from the male cone. They travel by wind until they get stuck to a female cone due to a sticky resin. Once stuck a pollen tube is grown and pollination occurs
gymnosperms
hmmm......i belive its the kettle family ; )
things that produce naked seeds like pine cones
There are 4 main types of phyla in Gymnosperms: - Cycadophyta - Ginkgophyta - Gnetophyta - Coniferphyla You can also get a nice description of the differences and answers to questions related on this webpage:
The two types of seeds are angiosperms (enclosed seeds) and gymnosperms (naked seeds).
1. Cycas, 2. Pinus, 3. Ephedra, 4. Gingko and 5. Taxus
