02:40Pollination and Flower Structure
69.0K
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

01:31Formation of Species
42.5K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

02:16Genetics of Speciation
19.6K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

02:45Biological Clocks and Seasonal Responses
38.8K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
