Protists, Fungi, Plants Flashcards
Protist
are a diverse collection of organisms.
Heterotroph
an organism deriving its nutritional requirements from complex organic substances
Eukaryote
an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus.
Decomposer
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Parasite
an organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other’s expense
Host
an animal or plant on or in which a parasite or commensal organism lives.
Fungi
any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools
Spore
a haploid reproductive cell which gives rise to a gametophyte.
Lichen
a skin disease in which small pimples or bumps occur close together
Nonvascular plant
Nonvascular Plants Defined. Nonvascular plants belong to the division Bryophyta
Vascular plant
a plant that is characterized by the presence of conducting tissue.
Gymnosperm
a plant that has seeds unprotected by an ovary or fruit. Gymnosperms include the conifers, cycads, and ginkgo.
Angiosperm
a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.
Photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Cellular respiration
is a set of metabolic reactions and processes that take place in the cells of organisms
Transpiration
is the process by which moisture is carried through plants from roots to small pores on the underside of leaves
Tropism
the turning of all or part of an organism in a particular direction in response to an external stimulus.
Gravitropism
is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it
Phototropism
the orientation of a plant or other organism in response to light
Asexual Reproduction
Asexual reproduction is a type of reproduction by which offspring arise from a single organism```
Toxoplasmosis
A disease that results from infection with the Toxoplasma gondii parasite
Malaria
A disease caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes
Giardia
An intestinal infection caused by a giardia parasite.
