Protists, fungi, and plants Flashcards
Protist
an organism that belongs to the kingdom Protista
Heterotroph
an organism that gets food by eating other organisms or there byproducts
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. Eukaryotes include all living organisms other than the eubacteria and archaebacteria
Decomposer
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material
Parasite
an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host’s expense
Host
an animal or plant on or in which a parasite or commensal organism lives
Fungi
an organism whose cells have nuclei, rigid cell walls, and no chloropyll
Spore
a reproductive cell
Lichen
a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees
Nonvascular plant
belong to the division Bryophyta, which includes mosses, liverworts, and hornworts
Vascular plant
a plant that is characterized by the presence of conducting tissue
Gymnosperm
Their naked condition stands in contrast to the seeds and ovules of flowering plants
Angiosperm
a plant that has flowers and produces seeds enclosed within a carpel
Photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
Cellular respiration
The chemical process that generates most of the energy in the cell
Transpiration
is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves
Tropism
the turning of all or part of an organism in a particular direction in response to an external stimulus
Gravitropism
is a turning or growth movement by a plant or fungus in response to gravity
Phototropism
the orientation of a plant or other organism in response to light
Asexual Reproduction
by which offspring arise from a single organism, and inherit the genes of that parent only
Toxoplasmosis
a disease caused by toxoplasmas, transmitted chiefly through undercooked meat, or in soil or cat feces
Malaria
an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells
Giardia
infection is an intestinal infection marked by abdominal cramps, bloating, nausea and bouts of watery diarrhea
