Protists and Fungi Flashcards
Protist
an organism that belongs to the kingdom Protista
Heterotroph
an organism that gets its food by eating other organisms or their byproducts and that cannot make organic compounds from inorganic materials
Eukaryote
A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota.
Decomposer
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Parasite
an organism that feeds on an organism of another species ( the host ) and that usually harms the host; the host never benefits from the presence of the parasite
Host
an organism from which a parasite 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 resistant to stressful environmental conditions and that can develop into an adult without fusing with another cell
Lichen
a mass of fungal and algalcells that grow together in a symbiotic relationship and that are usually found on rocks or trees
Nonvascular plant
the three groups of plants, ( liverworts, hornworts, and mosses ) that lack specialized conducting tissues amd 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 use sunlight, carbon dioxide, and water to make food.
Cellular respiration
the process by which cells use oxygen to produce energy from food.
Transpiration
The process by which plants release water vapor into the air through stomata
Tropism
The growth of all or part of an organism in response to an external stimulus, such as light.
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.
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.
Asexual Reproduction
is 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.
