### cell:

Tanniniferous cell
* are present or lacking.
* occur in the cortex, the medullary rays and the outer pith.

Transfer cell
* are abundant in the mesophyll of leaves
  - common in xylem and especially phloem parenchyma, primarily at the nodes
  - specialized parenchyma cells
* originate only from protoderm.

Transformed cell
* are atypical in many ways
  - cells that have incorporated DNA by transformation
* have the ability to reproduce themselves in large quantities in culture.
* proliferate, giving rise to brightly fluorescent calli.

Treated cell
* accumulate in the mitotic phase of the cell cycle.
* patch damage and build healthy tissue.
* take up plasmids, and then bacteria and plasmids reproduce.

Trophoblast cell
* attach to the uterine epithelium.
* develop into the placenta.
* invade the walls of the uterus and begin to proliterate.

### cell:

Tumor cell
* Many tumor cells exhibit strong cytoplasmic PAS positivity which is abolished by diastase digestion.
* Most tumor cells have different genes and proteins activated compared to normal cells
  - high levels of diglyceride
* Some tumor cells are resistant to chemotherapy.
* Some tumor cells contain brown melanin pigment
  - specific antigens that trigger the production of tumor-specific antibodies
  - vacuoles indenting the nucleus
* are also as likely to reside in the lungs
  - cells that have lost the map
  - cytogenetically heterogeneous
  - distinct from the benign stroma
  - osteocytes or osteoblasts and resemble normal osteoblasts
  - present within the vessels and soft tissue of the renal sinus
  - small with small nuclei and readily visible but small nucleoli
* are young, immortal cells that never grow up, mature and die off
  - grow, mature and die off
* can also inhibit normal blood cells from stopping the formation of a clot
  - directly activate the blood-clotting cascade
  - do things with their genes that are amazing
  - induce angiogenesis through a variety of soluble factors
* compete for nutrients, often at the expense of the normal cells' growth.
* contain all the possible target proteins.
* enter the lymph node via afferent lymphatics.
* fight back to beat immune system.
* grow faster than normal cells and therefore have an increased demand for nutrients.
* have a peroxide intolerance due to insufficient glutathione peroxidase and catalase
  - certain 'markers' that are only found on other tumor cells
  - low nuclear grade, inconspicuous nucleoli, and low mitotic activity
  - oval to round nuclei with stippled chromatin
* indicate dissemination of metastatic or primary brain tumors in the subarachnoid space.
* proliferate when that engine fails to operate.
* resemble hepatocytes.
* secrete a vascular permeability factor that promotes accumulation of ascites fluid.
* tell the host to provide a blood supply.

Tumour cell
* Some tumour cells continue to modify their properties as they grow.
* activate their own migration by producing a cell-surface bound chemotactic activity.

Type of cells
* Many types of cells possess receptors that bind steroid hormones.
* Some types of cells are more prone to abnormal growth than others.

Vegetative cell
* All vegetative cells contain two sets of chromosomes.
* are bacteriums
  - diploid, and gametes are the only haploid stages
* are the normal, photosynthetic cells formed under favorable growing conditions
  - site of photosynthesis and carbon fixation
  - uninucleate
* divide by binary fission.
* form spores under adverse conditions as a means of survival.
