- CELL PLATE in plant cells
- CELL FURROW in animal cells
- Spermatogenesis - formation of sperm cells
- Gametogenesis - producing gametes
- Oogenesis - formation of ova (egg cells)
- Ploidy – refers to the number of chromosome sets (chromosome number) in the nucleus
- Haploid (n) – half the set of chromosomes in the nucleus
- Diploid (2n) — two sets of chromosomes in the nucleus
- Angiosperm- the flowering plants
- When cell division goes wrong it may result to cancer
- Meiosis - nondisjunction of chromosomes during meiosis 1
- Mitosis cancer vs. tumor
- Nondisjunction – failure of sister chromatids or homologous chromosomes to separate correctly in the anaphase.
- Sporophyte - Spore-producing stage
- Gametophyte - gamete-producing stage
- Spores - germinate to develop haploid gametophyte
- Gametes - combine with other gametes to form (diploid) zygote
- Crossing over during meiosis produce recombinant chromosomes
- Parthenogenesis - unfertilized egg
- Apomixis - unreduced egg cell
- Agametic Reproduction - somatic cell/structure
- Vegetative Reproduction - somatic cell/structure
- Group selection explains group cooperation and altruistic behavior even in human
- organization and cooperation depends heavily on chemical and tactile communications
- Switching their reproduction mode depends on the environmental stimuli
