Protist, plant, and fungi Flashcards
Protist
An organism that belongs to the kingdom Protist.
Heterotroph
An organism that gets food by eating other organisms or their byproduct and that cannot make organic compounds from inorganic materials.
Eukaryote
An organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi but not archaebacteria or eubacteria.
Decomposer
An organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients.
Host
An organism from which a parasite takes food or shelter.
Fungi
A kingdom made up of nongreen, euaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients.
Spore
A reproducing cell or multicellular structure that is resistant to stressful environment conditions and that can develop into an adult without fusing with another cell.
Lichen
A mass of fungal and algal cells 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 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 food.
Angiosperm
A flowering plant that produces seeds within a fruit.
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.
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, also the release of water vapor into the air by the other organisms.
Tropism
Growth of all or part of an organism in response to an external stimulus, such as light.
Gravitropism
Is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it. 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 (negative phototropism).
Asexual Reproduction
Reproduction that does not involve the union of sex cells and in which one parent produces offspring’s that are genetically identical to the parent.
Toxoplasmosis
A disease caused by toxoplasmas, transmitted chiefly through under cooked 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 remitted 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
This infection is an intestinal infection marked by abdominal cramps, bloating, nausea and bouts of watery diarrhea.It is an infection is caused by a microscopic parasite that is found worldwide, especially in areas with poor sanitation and unsafe water.
