Cards

Term
Describe Telophase
Definition
Prophase in reverse: chromosomes uncoil, nuclear envelope reforms, nucleoli reappear, and the spindle breaks down.
Term
Describe Metaphase
Definition
The chromosomes cluster at the middle of the cell, with their centromeres precisely aligned at the equator of the spindle. This alignment is called the metaphase plate
Term
Describe Prophase
Definition
Chromatin coils and condenses forming chromosomes composed of 2 chromatids held together by a centromere. Nucleoli disappear and the centrioles separate. Microtubules assemble from the centrioles to form the mitotic spindle. The nuclear envelope fragments and the mitotic spindle attaches to the centromeres via kinetochores.
Term
Describe Anaphase
Definition
The centromeres of the chromosomes split and each chromatid now becomes a chromosome in its own right. The chromosomes are pulled toward each of the poles and the cell elongates.
Term
Describe Cytokinesis
Definition
A contractile ring of microfilaments forms a cleavage furrow and squeezes the cells apart in animal cells forming two daughter cells (these are plant cells, so a cell wall plate forms between them which completes the cell division process)
