protist, plant, fungi vocabulary Flashcards
a diverse taxonomic group and especially a kingdom (Protista synonym Protoctista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (as slime molds)
Protist
an organism deriving its nutritional requirements from complex organic substances.
Heterotroph
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.
Eukaryote
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Decomposer
an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host’s expense.
Parasite
an animal or plant on or in which a parasite or commensal organism lives.
Host
ural noun: fungi
any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
Fungi
a minute, typically one-celled, reproductive unit capable of giving rise to a new individual without sexual fusion, characteristic of lower plants, fungi, and protozoans.
Spore
a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees.
Lichen
Nonvascular plants belong to the division Bryophyta, which includes mosses, liverworts, and hornworts. These plants have no vascular tissue, so the plants cannot retain water or deliver it to other parts of the plant body.
Nonvascular plant
a plant that is characterized by the presence of conducting tissue.
Vascular plant
a plant that has seeds unprotected by an ovary or fruit. Gymnosperms include the conifers, cycads, and ginkgo.
Gymnosperm
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.
Angiosperm
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.
Photosynthesis
a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. … Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity.
Cellular respiration
the process where plants absorb water through the roots and then give off water vapor through pores in their leaves. An example of transpiration is when a plant absorbs water in its roots. YourDictionary definition and usage example.
Transpiration
the turning of all or part of an organism in a particular direction in response to an external stimulus.
Tropism
a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms.
Gravitropism
he orientation of a plant or other organism in response to light, either toward the source of light ( positive phototropism ) or away from it ( negative phototropism ).
Phototropism
a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.
Asexual Reproduction
disease caused by toxoplasmas, transmitted chiefly through undercooked meat, or in soil or cat feces. Symptoms generally pass unremarked in adults, but infection can be dangerous to unborn children.
Toxoplasmosis
an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells. The parasite is transmitted by mosquitoes in many tropical and subtropical regions.
Malaria
n intestinal infection marked by abdominal cramps, bloating, nausea and bouts of watery diarrhea. Giardia infection is caused by a microscopic parasite that is found worldwide, especially in areas with poor sanitation and unsafe water.Oct 13, 2015
