QUESTIONS LIST:

• prophage : viral dna that is embedded in the hosts dna during lysogenic infection.
• conjugation : hollow bridge is formed between two bacterial cells and genes move from one cell to another.
• hyphae : tiny threads of cytoplasm surrounded by plasma membrane and covered by a cell wall usually made of chitin.
• binary fission : reproductive process that involves only one parent (asexual reproduction) in which one cell divides to form two identical cells.
• cell walls : gram staining is a testing method used to determine if the bacteria's cell wall is composed mostly of peptidoglycan or not.
• endospore : a spore that is formed when a bacterium produces a thick internal wall that encloses its dna and will remain dormant until more favorable growth conditions.
• fungi : most are eukaryotes that have cell walls; are heterotrophs that feed by absorbing their food; and use spores to reproduce.
• movement : some bacteria are propelled by flagella, or whip-like structures, while others glide on slime they secrete or may be carried by air, water, or other methods.
• bacteriophages : viruses that infect bacteria.
• zygote fungi : ex. fruit and bread mold
• retrovirus : viruses containing rna which produce dna copy of their rna upon infecting a cell.
• viruses : particles of nucleic acid, protein and in some cases lipid; can reproduce only by infecting living cells.
• prokaryote : unicellular organisms that lack a nucleus; typically range in size from 1 to 5 micrometers.
• spores : tiny cell able to grow into a new organism.
• sac fungi : ex. yeasts and truffles.
• club fungi : ex. mushrooms and puffs.
• protist : eukaryotes that cannot be classified as animals, plants, or fungi.
