The Flora-1

Hi Guys!

   Well, this is the official newsletter of my blog! Feel free to read it! I looked up 'PLANTS' in Wikipedia and here's a few pictures and information about plants:

Dicksonia antarctica, a species of tree fern

A petrified log in Petrified Forest National Park.

The leaf is usually the primary site of photosynthesis in plants.

Plant cell structure

Dried dead plants  

The Venus flytrap, a species of carnivorous plant.   

Potato plant.

Timber in storage for later processing at a sawmill.

A section of a Yew branch showing 27 annual growth rings, pale sapwood and dark heartwood, and pith (centre dark spot). The dark radial lines are longitudinal sections of small branches which became included by growth of the tree.

Name(s)	Scope	Description
Land plants, also known as Embryophyta or Metaphyta.	Plantae sensu strictissimo	As the narrowest of plant categories, this is further delineated below.
Green plants - also known as Viridiplantae, Viridiphyta or Chlorobionta	Plantae sensu stricto	Comprise the above Embryophytes, Charophyta (i.e., primitive stoneworts), and Chlorophyta (i.e., green algae such as sea lettuce). Viridiplantae encompasses a group of organisms that possess chlorophyll a and b, have plastids that are bound by only two membranes, are capable of storing starch, and have cellulose in their cell walls. It is this clade which is mainly the subject of this article.
Archaeplastida, Plastida or Primoplantae	Plantae sensu lato	Comprises the green plants above, as well as Rhodophyta (red algae) and Glaucophyta (simple glaucophyte algae). As the broadest plant clade, this comprises most of the eukaryotes that eons ago acquired their chloroplasts directly by engulfing cyanobacteria.
