Cell Growth/division Test Flashcards
SA:V
As both increase, volume increases faster
2 main factors that control cell size
- information overload prevention
- exchange of materials
Advantages to asexual
- faster
* better in a stable environment, because if parent does well so does offspring
Disadvantages for asexual
In an unstable environment, if one does, probably all die
Advantages sexual:
- population can adapt because there is an increased genetic variation
- better in an unpredictable environment
Disadvantages for sexual
•slower
DNA is stored in _________ which are found in the __________ (___ only)
Chromosomes, nucleus, eukaryotes
Prokaryotes are found in _______
Cytoplasm
In prokaryotes…
One circular chromosome, just DNA
No proteins
In eukaryotes…
Linear chromosomes(1+)
In eukaryotes, DNA wound around ______ _______, coiled and coiled some more
Histone proteins
Prokaryotes undergo _____ ______
Binary fission
(Split in 2)
ASEXUAL
Interphase
G1, S, G2 <—- majority of time spent in cell cycle
M Phase
•includes mitosis and cytokinesis
Prophase
Longest phase, genetic material inside the nucleus condenses and the duplicated chromosomes become visible. Out side of the nucleus, spindles start to form
