### cell:

Dendritic cell
* act as gate keepers in the body's immune response process.
* are a specialised type of immune system cells.
* are a type of antigen presenting cell
  - inflammatory cell used to arm the immune system against invasion
  - an integral part of the immune system
  - cells found in the bloodstream of everyone
  - covered with a maze of membranous processes that look like nerve cell dendrites
  - essential components of the immune response that occurs in asthma
  - immune cells specialized to initiate immune responses
  - mononuclear cells with long cytoplasmic processes
  - particularly effective at presenting antigens to CTLs
  - present in tissues in contact with the external environment
  - specialized antigen-presenting cells
* are the principal stimulators of the primary mixed leukocyte reaction in mice
  - professional antigen-presenting cells of the immune system
* break the antigens on the cancer cell surfaces into smaller pieces.
* exhibit direct anticancer effector function.
* have the capability to both initiate immune response and regulate immune reactivity.
* pick up tumor peptides during the pre-treatment process.
* play a pivotal role in inducing immune responses to infection in vivo.
* receive their name from growths called dendrites that they produce.
  * are present in tissues in contact with the external environment. These tissues are the skin, and the inner lining of the nose, lungs, stomach and intestines. They can also be found in an immature state in the blood.

Different cell
* bear widely variable numbers of bad mitochondria.
* die at different rates.
* grow and die at different rates.
* have different activities
  - connexins in their gap junctions
  - functions in the body
  - jobs to do
  - structures and functions
  - many different shapes and sizes to adapt to their function
* perform different functions for the life of a multicellular organisms.
* use different amounts of all chemicals.
* vary in the permeability of their boundaries.

Differentiated cell
* More differentiated cells contain red cytoplasmic granules.
* are less likely to become cancerous
  - the mature cells that perform specialized tasks appropriate to the organ
* contain large amounts of specific proteins associated with the cell function.
* specialize in different physiological functions.

Diploid cell
* are cells that have pairs of chromosomes
  - with a full set of chromosomes
* have copies of both parents ' chromosomes and DNA
  - two alleles per trait, with one allele being donated from each parent
* have two complete sets of DNA, one set from each parent
  - homologous copies of each chromosome
* possess pairs of homologous chromosomes.

Dry cell
* are such wet cells with a minimum amount of water sealed in.
* are used in many electrical appliances
  - ' are a type of chemical cells. Dry cells are commonly used today, in the form of batteries. Dry cells are used in many electrical appliances

Dysplastic cell
* differ from normal cells in their shapes and the size of their nuclei.
* lie in a continuum between benign and fully malignant.

Effector cell
* act to get rid of the invader.
* are short-lived cells that combat the same antigen.
* kill tumors using the same mechanisms they use to kill microorganisms.

Elongated cell
* can give a spurious drift towards higher DNA contents.
* cause the plant to bend and grow toward the light.

Embryonic cell
* are a good example of how there can be cell division without growth
  - alive sure, but only in the literal sense
  - in general pig
  - less likely to be rejected by the body's immune system
  - totipotent in their early stages
* have the potential to develop into all basic tissue types.
* produce signals that alter the behavior of neighboring cells.
