Life science: Genes & Molecular Machine
Types of Cells
Eukaryotic
An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes.
Prokaryotic
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles
Heredity
Genotype
the genetic makeup of an individual organism.
Phenotype
The visual features of an organism
Cell Division
Mitosis
Body cell division in which the nucleus divides
containing the same number of chromosomes. (Happens in all Eukaryota cells asexually)
Meiosis
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes (sex cells) and plant spores. (Happens through sexual reproduction)
Flowering Plants and Seeds
Dispersal
Dispersal methods for seeds are wind,air,animals, and mechanical propultion
Reproduction
Reproductive parts of the flower is the stamen(male),and the pistil(female).Plants can reproduce asexually or sexually through pollination.
