production of new cells Flashcards
define chromatids
chromotid is a replicated copy of a chromosome visible during cell division
definition of chromosome
chromosome is the structure containing hereditary material; composed of DNA that codes for all the characteristics of an organism
what is the definition of a chromosome complement
A chromosome complement is the characteristic number of chromosomes in a typical cell of an organism
define a diploid cell
a diploid cell describes a cell containing tow sets of chromosomes
what is the equator?
it is the position of a spindle where the chromosomes are attached during mitosis
what is the definition of mitosis
mitosis is the division of the nucleus of a cell that leads to the production of two genetically identical diploid daughter nuclei
define organ
an organ is a group of different tissues that work together to carry out a particular function
example is the heart and lungs
what are the definition of poles?
Poles are the opposite ends of a spindle to which chromatids migrate during mitosis
define replication
replication is coping of the DNA to produce chromatids before mitosis
what is the definition of self renew
self renew is the property of stem cells by which they divide by mitosis to produce more stem cells.
define specialised?
description of a cell that has become differentiated to carry out a particular function
define spindle fires
spindle fires are threads produced during mitosis to pull chromatids apart
what is a stem cell?
Stem cell is a unspecialised cell capable of diving into cells that can develop into different cell types
what is the definition of a system
system is a group of organs that work together to carry out a particular function
an example is circulatory, respiratory and digestive
give the term applied to a group of similar cells that carry out the same function
tissue
