Protist and Fungi Flashcards
Protist
an organizm that belongs to the kingdom Protista
heterotrogh
an organism that gets food by eating other organisms or their byproducts and that cannot make organic compounds from inorganic materials
parasite
an organism that feeds on an organism of another species and usually harms the host
host
an organism from which a parasite takes food or shelter
fungi
an organism whose cells have,nuclei,rigid cell walls, and no chlorophyll and that belongs to the kingdom Fungi
spore
a reproductive cell or multicellular structure that is resistent to stressful enviromental conditions and that can develop into an adult without without fusing with another cell
a mass of fungal and algal cells that grow together in a symbiotic relationship and that are usually found on rocks or trees
Lichen
novascular plant
the 3 groups of plants that lack specialized conducting tissues and true roots, stems, and leaves
Vascular Plant
a plant that has specialized tissues that conduct materials from one part of the plant to another
Gymnosperm
a woody, vascular seed plant whose seeds are not enclosed by an ovary or fruit
Angiosperm
a flowering plant that produces seeds within a fruit
Photosynthesis
the process by which plants, algae, and some bacteria
Cellular respiration
is 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.
Transpiration
is 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.
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. It is a general feature of all higher and many lower plants as well as other organisms.
Phototropism
the orientation of a plant or other organism in response to light, either toward the source of light ( positive phototropism ) or away from it
Asexual 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.
Toxoplasmosis
a 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.
Malaria
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.
Giardia
Giardia infection is an 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.
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
a device or installation that is used to break down a chemical substance.
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.
