Plantae

Green seaweed has a very close relationship with plants
Experts say that water is an ancestor of green plants, because there is some similarity in the characteristics of the water and green plants
the plant who have now is the result of the evolution of green seaweed

The characteristics of living things classified Plantae
1. Multiseluler body structure, eukariotik, cells that have already formed a network specialization and organ
2. Chlorophyll contains a and b and karotenoid, store food in the form of flour and have a cell wall and cellulose
3. Protect the fetus from the drought with water supply and nutrition to the body structure in the female
4. Have a rotation cycle of living offspring (metagenesis)



Moss plant

A. The characteristics of the structure Moss
1. Small size
2. High approximately 2 cm-50 cm
3. Not have a network carrier
4. Water distribution is done with the diffusion
5. Not have a root, stem and leaves the actual
6. Rhizoid roots of the functions inherent in the substrate / soil and absorb water, minerals from the soil in
B. Reproductive Moss
1. The asexual and sexual
2. Asexual performed with the gemma (closed), the distribution of spore and fragmentation
3. Sexual done with meetings between spermatozoid (produced anteredium) and ovum (arkegonium)
4. Based on the location and arkegonium have anteredium:
a. homotalus Moss : settle one (in the body have anteredium and arkegonium)
b. heterotalus Moss : settle two (one in the body have anteredium or arkegonium only)

C. Classification Of Moss
1. Hepatophyta / Hepaticopsida
( Hati moss)
- The form sheet
- Called thallus plants do not yet have the root, stem and leaves the actual
- Structure thallus called lobus
- Example:
Marchantia (most popular)
Asexual reproduction by gemma
his(Moss) Sexual with anteredium and arkegonium
There are 2 species:
Marchantia polimorpha
Marchantia geminata

2. Anthocerophyta / Anthoceropsida (Tanduk Moss)
- found on the border of river
- Almost the same as the only sporofitnya Moss heart-shaped capsule
- reproduction also have metagenesis
- Examples
Anthoceros sporophytes

C. Bryophyte / Bryopsida (leaves of Moss)
- Moist and shady places (polar / tropical / desert)
- Usually formed or ground floor of the forest patch on a stick
- Own cuticle and stomata
- In the dry season can be experienced dormansi
- reproduction metagenesis
- Example:
Spagnum sp
Polytrichum sp

D. Role Moss
As a pioneer vegetation
Ability to absorb water can also provide water when drought
How to fuel (eg Spagnum sp)
You can substitute for cotton
For Hepatitis drugs (Marchantia polymorpha)
