Document Summary

9+2 organization: name for the pattern of arrangement that microtubules are placed in to form flagella or cilia (pairs of microtubules placed in groups of 9). Alternation of generations: in plants, they spend half of their lives as haploid (gametophyte) half as diploid (sporocyte). Amoeboid (amoeboid) movement: type of locomotion in protists, involves the use of molecular motors (myosin motors on an actin track) to push endoplasm against the ectoplasm (or turn endoplasm into ecoplasm?) to push the entire protist forward. Asexual reproduction: reproduction where offspring comes from a single parent. Autotroph: an organism that produces energy for itself without consuming other organisms. Basal body: an organ formed from a centriole and some microtubules. Bikont: a eukaryotic organism (cell?) that has two flagella. Cellular division of labour: the division of labour for the organelles of a cell. Cellular gliding: an early form of eukaryotic motion, where the centrosome uses microtubules to push against the inside of the cell, moving it.
