Protist and Fungi

protozoan: one-celled animal-like organism with a nucleus.



cilia: short hair like part on the surfice of the cell.

sporonzoans: protozoans that reproduce by forming spores.

spores: special cells that develop into new organisim.

algea: plantlike protist.

multicellular: means that an organism has many different cells that do not certain jobs for the organism.

slime mold: fungus like protist that are consumers.

hyphae: network of threadlike structure most fungi are made up.

sporangium fungi: fungi that produce spores in sporangia.

sporangia: structure on the tips of hyphae that make spores.

club fungi :fungi with club-shaped parts that produce spores.

sac fungi:produce spores in saclike structures.

budding: reproduction in with small part of the parent grows into a new organism.

mutualism: arrangement in wich both organism are benefit.

lichen: a fungus and an organism with chlorophyll living thogether.

Virues and Monerans

Virus: it is made of chromosomes-like part sorruonded by a protein coat.

Host: is an organism tbhat provides food for a parasite.

Parasite: is an organism that lives in or on an other living thing and gets food from it.

Interferon: is a chemical subtance that interfers with tha way viruses reproduce.

Vaccines: sustance made from weakened or dead viruses.

Bacteria: very small, one-celled monerans.

Colony: a group of similar cells growing naxt to each other that do not dependon each other.

Capsule: bacteria´s sticky outer layer.

Flagellum:  long whiplike thrad.

Fission: the process of one organism dividing into two organisms.

Asexual reproduction: the reproduction of a living thing from only one parent.

Endospore:is a thick-walled structuire that forms inside the cell, enclosing the all of the nuclear material and some cytoplasm.

Saprophytes: are organism that use dead materials for food.

Decomposers: living hing that get their food from breaking down dead matter into simpler chemicals. 

Koch´s postulate:are steps for proving thta a desease is caused by a certain microscopic organism.

Comunicable desease: deseas that can be passed from one organism into another.

Antibiotic:are chemicals subtances that kill or slow the grouth of bacteria.

Biotechnology: the use of living things to solve practical problems.

Pasteurization: tha process of boiling milk to kill harmfull bacteria.
