The Study Guide Flashcards
Sexual definition and examples
Parents combine genetic information for offspring
Meiosis in humans
Asexual definition and examples
Parent produces an identical copy of self
Budding ,stolons ,vegetation propagation
Interphase is?
The portion of the cell cycle in between cell division
Mitosis?
Division of the nucleus
Cytokinesis
Division of the cell into two new daughter cells
Material for new cell walls and membranes to gather and join at the equator of the cell in plants
Cell plate
Cell is pinched into two by a groove made up of the cytoskeleton fibers in animals
Cleavage furrow
Mitosis division of the cell —-. In which chromosomes in the parent cell divide into two —- sets. This occurs in —- reproduction and in the reproduction of cells for out bodies to —- and —-.
Nucleus Identical Asexual Grow Develope
Four stages of mitosis is order
Prophase
Metaphase
Anaphase
Telephase
After mitosis, xxxx occurs to separate the cytoplasm to form xxxx identical cells
Cytokinesis
Two
The genetic material xxxx is arranged into xxxx
DNA
Chromosomes
Xxxx is when DNA is all unwound
Chromatin
One doubled chromosome
Two Sister chromatids
Two sister chromatids are attached by a xxxx to form a chromosome
Centromere
Humans have xxxx total chromosomes. These pairs of chromosomes are known as xxxx. In all sexually reproducing species, chromosomes occur in these pairs xxxx from mom, xxxx from dad.
46
Sister chromosomes
Half
Half
Diploid (2N) cells
Full amount of chromosomes eg skin cells
Haploid
Half amount of chromosomes Eg gametes (sex cells)
Humans have totally xxxx chromosomes. Because we are diploid, we have xxxx pairs of chromosomes. Our sperm and egg cells are haploid so they only have a total of xxxx chromosomes

Gametes
Egg and sperm
Meiosis
Division of the cell nucleus in which chromosomes in the parent cell divide, reducing the chromosome number in half. Occurs for sexual reproduction.
