Flashcards in Unit 3 and Unit 4 Deck (16):
stages of mitosis
PMAT (prophase, metaphase, anaphase, and telophase)
involves one parent, produces genetically identical offspring
parent cell splits into two daughter cells that are identical in size
parent organism breaks into fragments and new organisms develop from those pieces
parent cell forms a bud that stays attached; when fully developed it breaks away and forms a new organism
the production of an organism without fertilization
involves two parents; produces genetically unique offspring
haploid cells that contain HALF the number of chromosomes found in other cells of the organism
Human gametes are...
sperm (males) and eggs (females).
two gametes unite
A fertilized cell is also called...
longest phase of mitosis where chromatin condenses and the nuclear envelope breaks down; centrioles begin to move to opposite sides of the cell
spindle fibers attach to the centromeres of each pair of sister chromatids; sister chromatids line up on the equator of the cell
sister chromatids separate and the centromeres divide; at the end each pole has a complete set of chromosomes
chromosomes begin to uncoil and form chromatin; spindle also breaks down and nuclear membranes form
