Because of that, most Bryophyta live in moist environment. They have no vascular systems or roots, since all cells could extract water from their aquatic environment. Yet they have no true leave, root, or stem structure, instead, they support themselves via a root-like structure called a rhizoid. Bryophyta reproduce through producing spore, which are tiny cells that, if they land in a suitable environment, develop into a new plant.

Example：
mosses - Bryum caespiticium
The characteristic helps us to identify mosses is the lack of stem or true leave, which also implies lack of vescular system]]> 2018-06-23 01:42:43 UTC https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268270001 ch13801191460 https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268270149 Filicinophyta is the first group of plants to develop vascular system. They had developed xylem and phloem vessel to transport water and nutrients. Meanwhile, they have leave, stem, and root.(yet the leaves are pinnate – consisting of large fronds divided into leaflets). Like Bryophyta, Filicinophyta also produce spores. The clustered structure that can be observed under the leaf of Filicinophyta are called sori, or fruit dots, which produce millions of spores, each with the chance to develop into a new fern plant.

Example:
Fern -  Cibotium barometz
features that helps to identify ferns are their pinnate leaves.

They are  gymnosperm, cone bearing seed, woody plants with secondary growth. They have developed vascular system, with true leave, stem and root.(yet their leaves are waxy and needle like) They reproduce by non-motile gametes (seed) which are found in  cones.

Example:
Pine tree - Cedrus deodara
feature helps to identify coniferophyta is their needle like leaves and cone seeds.]]> 2018-06-23 01:46:45 UTC https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268270164 ch13801191460 https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268270176 Angiospermophyta are commonly called flowering plants, who has dominate over half of the plant kingdom today. They has developed vascular system, and true leave, stem and root(Though those structures may be highly varied in individuals). The most obvious difference between flowering plants and the other phyla is the development of flowers. Angiospermophyta reproduce via the seed produced in the flower and sometimes the ovary will develop into fruit which gives further protection to the seed. ]]> 2018-06-23 01:47:01 UTC https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268270176 ch13801191460 https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268302856 2018-06-23 18:14:41 UTC https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268302856 ch13801191460 https://padlet.com/ch13801191460/j4hvo4nvlc95/wish/268303284 Chinese Rose - Rosa chinensis
