Document Summary
Overview: a world in a drop of water. In the past, taxonomists classified all protists in a single kingdom, For example, algae known as chlorarachniophytes evolved when a heterotrophic eukaryote engulfed a green alga. This process likely occurred comparatively early in evolutionary time, because the engulfed alga still carries out photosynthesis with its plastids and contains a tiny, vestigial nucleus called a nucleomorph. The gene allows t. vaginalis to feed on epithelial cells. It spends most of its time inside human liver and blood cells, and continually changes its surface proteins, thereby changing its. Identification of a gene that may confer resistance to chloroquine, an antimalarial drug, may lead to ways to block drug resistance in. The genes are not organized into chromosomes but are packaged into small units with duplicates of a few genes. In ciliates, reproduction and conjugation are separate processes. o. In a real sense, ciliates have sex without reproduction.
