Asexual reproduction
Reproduction in unicellular/multicellular organisms
Repair and replacement
Replace cells from normal wear and tear or from injury
Growth
From fertilized egg to multicellular organism composed
Difference between sexual and asexual reproduction
Sexual- jointing of 2 sex cells
Asexual- creation of offspring from a single parent
What limits cell size

Chromatin
String like threads when the cell is not actively dividing
Chromosomes
Super coiled units of dna that are condensed and x shaped inside the dividing nucleus
Centromeres
Holds 2 chromatids together
Gene
Segment of dna that codes for a trait
Sister chromatids
Identical copies
Duplicated chromosomes are also known as … and attached at..
Sister chromatids and attached at the centromere
Homologous chromosomes
Meaning it has the same relation,relative position, or gene sequence from each parent
Somatic cells
Body cells, makes up most of ur body tissue and organs
Gametes
Sex cells, haploids
Difference between haploid and diploid
Diploid - 2 sets of chromosomes
Haploid - 1 set of chromosomes
Autosomes
Containing genetic info that’s not sexual (instructions)
Sex chromosomes
Directly controls sex characteristics
3 parts of the cell cycle
Interphase - longest state
G1- growths
S - dna replication
G2- grows again/ error checks
Check point
Cell size and nutrient check
