Asters are star-shaped microtubule arrays found in animal cells. They form around the centrioles during mitosis and help ensure each daughter cell has the appropriate number of chromosomes.
Chromatin
Asters are one of my favorite; there are hundreds of cultivars (varieties) of which germination (under proper conditions) can occur anywhere from 7 days to probably as much as 21 days depending on the variety.
During evolution, chromosomal cariation in structure cannot occur due to
Landslides occur in seasons of heavy rains they occur mostly in places where the soil structure is weak
The mantle.
Cleavage planes occur due to a weakness or propensity to fracture in a crystalline structure.
Meiosis occurs in the sporophyte.
