- asexual reproduction
- reproduction involving only one parent
- reduction division
- cell division that occurs in meiosis and results in haploid cells
- chromosome
- distinct wormlike structures formed from chromatin during cell reprduction
- microtubules
- tiny tubes that make up most of a cell's cytoskeleton
- anaphase
- mitotic stage where chromosomes separate at the centromeres
- homologous pair
- in diploid cells, a pair of identical chromosomes
- polyploid
- having more than the diploid number of chromosomes
- blastula
- hollow ball of cells formed during the early stages of embryological develpoment
- somatic cells
- body cells, (cells other than germ cells)
- germ cells
- the only cells that can undergo miosis, found in sex organs
- DNA replication
- the process of doubling the DNA that occurs before mitosis
- asters
- microtubles and fibers that radiate our from centrioles
- ovum
- one egg
- centriole
- in animal cells, a cytoplasmic organelle that organizes the mitotic spindle fibers during cell reproduction
- crossing-over
- an exchange of chromosomal material between homologus pairs
- prophase
- the first stage of mitosis when chromosomes form chromatin and the nuclear membrane is absorbed
- diploid
- having two of each chromosome
- cytokenesis
- cytoplasmic divison that follows division of the nucleus
- haploid
- half the number of diploid chromosomes
- metaphase
- the stage of mitosis where duplicated chromosomes line up along the center of the mitotic spindle
- spermatogenesis
- the meiotic process that results in the formation of sperm cells
- centromere
- part of the chromosomes where the chromatids are joined together
- oogenesis
- the meiotic process that results in the formation of eggs
- mitosis
- dupication and division of chromosomesand nucleus during cell reproduction
- sexual reproduction
- reproduction requiring two parents
- meiosis
- cell division to produce sex cells
- chromatid
- one of the two strands that make up chromosomes
- chromatin
- the coils of DNA and protein that condense to form chromosomes
