### plant | embryo:

Dechorionated embryo
* can swim clumsily when prodded.
* lie on their sides when at rest, yolk sac obliquely upwards.

Develop embryo
* go through stages
  - various stages
* have materials.
* receive nutrients.
* require oxygen.
* touch membranes
  - shell membranes

Drosophila embryo
* develop in the egg membrane.
* have a tremendous capacity to repair mispatterned tissues.

Embryo donation
* controversial process from both an ethical as well as a legal standpoint.
* is another option if the male partner is also infertile.

Fossil embryo
* are the preserved remains of organisms that have yet to hatch or be born.
* reveal early animals Paleontologists have found the oldest known embryos

Human embryo
* Most human embryos go through evolutionary stages
* Most human embryos go through various evolutionary stages
  - reach uteruses
* Most human embryos undergo cell division
  - multiple cell division
* Some human embryos come into existence.
* are extremely sensitive to poor culture conditions and toxins
  - fully human
  - just that, human
* have to nestle down in a good home, in the uterus.

Mammalian embryo
* Most mammalian embryos have structures.
* Most mammalian embryos undergo cell division
  - the same structures
+ Amniote: Tetrapods :: Evolutionary biology
  * They are the land vertebrates which lay cleidoic eggs. Mammalian embryos have the same structures.

Mutant embryo
* derived from null oocytes survive to the larval stage.
* exhibit a severe somatic muscle phenotype.
* fail to elongate their heads resulting in a bloated head appearance.
* have defects in cell division time, osmotic sensitivity, cytoplasmic streaming.
* lie motionless in the vitelline membrane and fail to hatch.
* show a delayed cell cycle, possibly consistent with a lack of thymidine
  - two types of spindle formation defects

Shark embryo
* Most shark embryos receive nutrients.
* Some shark embryos get their food first from a yolk.
* receive nutrients from several sources

Somatic embryo
* Some somatic embryos grow into trees.
* occurs either directly on the explant or more often in callus culture.

Vertebrate embryo
* All vertebrate embryos look much alike.
* Most vertebrate embryos go through stages.

Whale embryo
* Most whale embryos develop features.
* form both fore- and hind limb buds.

Emergent plant
* grow along the shoreline or in shallow, marshy areas.
* have some parts of the plant in contact with the air above the water's surface.
* reproduce by seed during natural drawdown cycles caused by drought.

### plant:

Endemic
* Many endemics exist on Caribbean islands or isolated mountain chains.
* affect fire ant populations at low levels all of the time.
* are diseases
  - important to understand in infectious diseases
  - plants
* belong to genera abundantly represented in the regional flora.
* can easily become endangered or extinct because of only living in a small area.
+ Endemism: Ecosystems
  * Endemics can easily become endangered or extinct because of only living in a small area. They are also vulnerable to the actions of man, including the introduction of new organisms. By the end of the century, the petrels were thought to be extinct. Cedars, whose numbers were low as a result of centuries of shipbuilding, were nearly made extinction in the 20th Century by the introduction of a parasite. Both petrels and cedars are very rare today, as are other species endemic or native to Bermuda.

### plant | endemic:

Wage discrimination
* can include more than just inequalities in weekly salaries.
* is endemic.

Entire plant
* Most entire plants get nutrients
  - have appearances
* Some entire plants consist of fronds.
* Some entire plants contain juice
  - silica
  - grow feet
* are known to die as the result of severe infestations.
* can die if flooded for only a few days during the growing season.
  - bushy appearances
