He explains that the eukaryotic cell‚ and thus we ourselves‚ exist because a cell dependent on hydrogen merged with a mitochondrial ancestor that produced hydrogen and was capable of respiration. This symbiotic relationship‚ that would give rise to all multicellular life on earth‚ was the most unlike step in evolution. Much more likely was the actual origin of life‚ caused by the different concentration

or more cells‚ they are classified into 2 groups which are unicellular organisms and multicellular organisms. Plants and animals are made up of cells too. There are two basic classes of cells‚ prokaryotic and eukaryotic cells. The structurally simpler‚ prokaryotic cells are found among bacteria. All other types of organisms such as protists‚ fungi‚ plants and animals consist of structurally more complex eukaryotic cells. In this experiment‚ we took an animal cell (cheek cell) and a plant cell (onion

Origin of Life 1. The four stages of hypothesis for the origin of life on Earth by chemical evolution is * Abiotic synthesis of small organic molecules * The joining of small molecules into macromolecules * Packaging of these molecules into protobionts * The origin of self replicating molecules that made inheritance possible. 2. A.I. Oparin‚ and J.B.S. Haldane hypothesized a reducing environment. Stanley Miller and Harold Urey did lab experiments that showed that the abiotic

Fungi are: Multicellular (except for yeasts) Eukaryotic Heterotrophic Decomposers: decompose dead and decaying material -Recyclers! -Secrete enzymes OUTSIDE bodies - Absorb digested nutrients Hyphae: long‚ slender‚ root-like filament Septa: cross-walls across hyphae (not

Historically‚ protists were treated as a biological kingdom formally called the Protista‚ and included mostly unicellular organisms that did not fit into the other kingdoms. Molecular information has been used to redefine this group

On Locomotion/Movement: a. Are all plants sessile (permanently attached; not freely moving)? “Walking” Palms‚ Climbing Vines– Some Plants Are Not “Sessile” b. Are all animals mobile? This is true. Animals are a major group of multicellular‚ eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop‚ although some undergo a process of metamorphosis later on in their life. Most animals are motile‚ meaning they can move spontaneously

PROTISTA GENERAL CHARACTERISTICS * Eukaryotic * Unicellular * Microorganisms * Asexual/sexual reproduction * Flagella & Cilia with 9+2 microtubules ORIGIN * The term "protist" is derived from the Greek protiston‚ meaning the "first of all ones." * Individual protists tend to be quite small‚ either unicellular or an undifferentiated multicellular mass. At one point‚ "Protista" encompassed everything that wasn’t an animal or plant‚ until the advent of cellular biology which
