biological process
process specifically pertinent to the functioning of integrated living units
vertebrate eye development
overview about the vertebrate eye development
Oxygen rebound mechanism
catalytic pathway
sporogony
process of sporozoite formation beginning with division of a zygote
Ontogenetic niche shift
ecological phenomen, when ecological niche of an individual changes its breadth and position during ontogeny
menstruation
cyclic, physiologic discharge through the vagina of blood and endometrial tissues from the nonpregnant uterus
long-term memory
memory process that deals with the storage, retrieval and modification of information a long time (typically weeks, months or years) after receiving that information
gene expression
conversion of a gene's sequence into a mature gene product or products
DNA replication
cellular metabolic process in which a cell duplicates one or more molecules of DNA
excretion
process of elimination by an organism of the waste products that arise as a result of metabolic activities
ecological succession
process of change in the species structure of an ecological community over time
programmed cell death
biological process
peristalsis
wavelike sequence of muscular contraction and relaxation that passes along a tubelike structure
plant dispersal
physical distribution of plants in various forms and stages of development through time and space
ammonification
part of the nitrogen cycle in which microorganisms decompose nitrogen in proteins and amino acids into ammonium ions
menarche
individual person's first menstrual cycle
metaphase
cell cycle phase, following prophase or prometaphase in higher eukaryotes, during which chromosomes become aligned on the equatorial plate of the cell
signal transduction
cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell
biosynthesis
multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined to form macromolecules
CAM photosynthesis
metabolic process
phototropism
growth of an organism in response to a light stimulus
regulation of postsynaptic membrane potential
Any process that modulates the potential difference across a post-synaptic membrane.
protein splicing
post-translational removal of peptide sequences from a protein sequence
futile cycle
type of metabolic process
taxis
directed movement of a motile cell or organism in response to an external stimulus
cell recognition
process in which a cell in an organism interprets its surroundings
organogenesis
process by which the ectoderm, endoderm, and mesoderm develop into the internal organs of the organism
Thermotaxis
The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.
ossification
formation of bone or of a bony substance, or the conversion of fibrous tissue or of cartilage into bone or a bony substance
proprioception
sense of the relative position of one's own parts of the body and strength of effort being employed in movement
lateral inhibition
Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells.
Chitting
method of preparing potatoes for planting
growth
the increase in size or mass of an entire organism, a part of an organism or a cell
growth
the increase in size or mass of an entire organism, a part of an organism or a cell
nervous system development
the process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state
gametogenesis
biological process
heat shock response
effect of subjecting a cell to a higher-than-optimal temperature; causes protein misfolding, cytoskeletal rearrangement, organelle localization changes, ATP production decrease, unsafe pH drop, decreased protein translation and RNA splicing changes
long-term potentiation
persistent strengthening of synapses based on recent patterns of activity
placental expulsion
emergence of placenta from birth canal after birth
facilitated diffusion
biological process
cognition
mental action or process of acquiring knowledge and understanding through thought, experience, and the senses
DNA mismatch repair
system for fixing base errors of DNA replication and repairing some forms of DNA damage
reproductive behavior
specific behavior of an organism that is associated with reproduction
hydrotropism
growth or movement in a sessile organism toward or away from water, as of the roots of a plant
dehiscence
splitting at maturity along a built-in line of weakness in a plant structure in order to release its contents, and is common among fruits, anthers and sporangia
viral entry into host cell
biological process
saliva secretion
production of saliva
co-adaptation
process by which two or more species, genes or phenotypic traits undergo adaptation as a pair or group
pyrimidine nucleotide metabolic process
The chemical reactions and pathways involving pyrimidine nucleotides
chromosome segregation
process in which genetic material, in the form of chromosomes, is organized into specific structures
Cladoptosis
Shedding of branches by woody plants
