Document Summary

An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs. A small region of cytoplasm adjacent to the nucleus that contains the centrioles and serves to organize microtubules. hoanoflagellates are small single-celled protists that live in freshwater and marine environments. They have one flagellum, which enables them to eat and move. Around this flagellum is a collar-like ring of microvilli. Chromosomal crossover (or crossing over) is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes. Organism that is unable to obtain its carbon from carbon dioxide. Instead, heterotrophs obtain carbon by feeding on the organic material present in other organisms, living or dead. It"s a classification category for a clade that"s. A substance that when introduced into the body stimulates the production of an antibody. An endospore is a dormant, tough, and non-
