### plant | phytoplankton:

Marine phytoplankton
* are extremely tolerant to changes in salinity
  - the first link in the large marine food chain
* is most productive where upwellings bring nutrient-rich waters to the surface.

Planktonic algae
* are a leading cause of water quality problems in reservoirs.
* can occur briefly at various stages in pond development.
* live free-floating in the ocean and in the largest to smallest lakes and streams.
* produce most of the molecular oxygen in the Earth's atmosphere.
* serve as the base of the food chain.

### plant:

Plant life
* All plant life contains some aluminum in a hydrophilic chelated colloidal form.
* Most plant life has ability.
* Some plant life helps predators.
* can decline due to drought , disease, or human activity
  - provide natural sources of chemicals found in many medications
* consists of mesquite bushes, cactus and lowland grasses.
* depends on sunlight, moisture and good soil in order to thrive.
* determines the kinds and quantities of animals an environment can support.
* differs dramatically from dune ridge to dune ridge.
* dissolves the rock and assimilates it into itself transforming it into plant.
* exists in precarious harmony with representatives of the insect world
  - profusion
* includes bald cypress, which secretes tannin that gives the river waters a dark color
  - blueberry bushes and perennial succulents such as lady's slipper
  - lichens and small shrubs
  - mature hardwoods
  - some grass and shrubs , algae , lichen , fungi , and bacteria
  - woody and herbaceous communities
* is able to sustain many birds all year without supplemental feeding
  - abundant as well, including a few endemic species
* is an important part of freshwater ponds, helping to create a balanced ecosystem
  - organism
  - characteristic of bottom ground, offering a variety of species
  - composed of creeping shrubs, tufted grass-like plants, lichens, and mosses
  - critical to all three life cycles
* is limited to marine algae
  - mosses and lichens
  - located in waterfalls
  - low growing and shallow rooted
  - predominantly representative of a mature oak-hickory forest
  - prolific with scores of aquatic and riparian plants
  - rich in medicinal herbs, fruits and berries
  - sparse in the desert and wildlife depends on it to survive
+ Antarctica: Gondwana
  * Antarctica is considered a desert. No humans live in Antarctica permanently. However, about 1,000 to 5,000 people live through the year at the research stations in Antarctica. Only plants and animals that can bear cold live there. The animals include penguins, seals, nematodes, tardigrades and mites. Plant life includes some grass and shrubs, algae, lichen, fungi, and bacteria.

Plant propagation
* can also refer to the artificial or natural dispersal of plants
  - fall into two categories, sexual and asexual propagation
* is both an art and a science.
* is the process of producing a new plant from an existing one
  - more plants either asexually or sexually
* refers to the sexual and asexual reproduction of plants.

Plantlet
* are new, small plants that grow on the leaf edges of a parent plant
  - tiny plants that grow along the margins of certain leaves
  - young or small plants
* develop from the bulbils while they are still attached.
* grow easily if they are separated from the flower stalk when they are rooted.
* start easily.

### plant | plantlet:

Small plantlet
* arise on the main veins of the leaf near the base.
* develop at the point of attachment of each flower.
