Cell Division
- What is mitosis? What is
the importance of mitosis?
Mitosis is the process in which one
eukaryoticidentical to the parent cell ( cell divides into two generallycells (^)
identical, since alterations in genetic
material can organelles may boccur, more distributee or lessd between (^)
the daughter cells, etc.)
Mitosisreproduction of eukary is fundamental footes, for ther asexual (^)
embryonic development, for the growthof pluricellular beings and for tissue
renewal.
- Why in some cases is
mitosis a synonym of
reproduction?
In some living beings asexual
reproduction occurs by many mbinary division, schizogony, budding,eans:
grafting, etc. In asexual reproduction of
eukaryotes mitosiswhich the constituent cells o is the mechanism bf the new y
beings are made.
The term mitosisprokaryotes since does not apply toit involves nuclear (^)
division and eukaryotic structures.
- What is the importance of
mitosis for the embryonic
development?
Every embryo grows from a singlthat suffers mitosis and generates othe celler (^)
cells that also divimitosis forming tissues ande themselves bd completey (^)
organs. The perfect regulation and
control of each oare fundamental for the creatiof those cell divisionsn of a (^)
normal individual. Without mitosis the
embryonic development would beimpossible.
- What are some examples of
organs and tissues where
mitosis is more frequent, less
frequent or practically absent?
Generally in frequent in tissuesvertebrates mitosis that require intense is more
renewing due to their functions, like
epithelial tissues anIn plants the meristem tissue d the bone marrhas ow.
numerous cells undergoing mitosis.
Mitosis take place with low frequency in
tissues ofbones in a slow redults and the connectivenovation, like the (^)
tissues.
In some aabsent, like dult tissuesthe nervous tissue a mitosis is almostnd the (^)
striated mcardiac). Tuscle tissue (skeletal anhe nervous tissue developsd (^)
from stimulus by development of new
electricalthe striated m networks beuscle tissue grows bytween cells an d
