P,p,f Flashcards
Protist
: any of a diverse taxonomic group and especially a kingdom
Heterotroph
an organism deriving its nutritional requirements from complex organic substances.
Eukaryote
A eukaryote is any organism whose cells have a cell nucleus and other organelles enclosed within membranes
Decomposer
Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition
Parasite
n biology, parasitism is a non-mutual relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally parasite primarily meant an organism visible to the naked eye, or a macroparasite
Host
a person who receives or entertains other people as guests
Fungi
A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms
Spore
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.
Lichen
A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi in a symbiotic relationship. The combined lichen has properties different from those of its component organisms
Nonvascular plant
Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Although non-vascular plants lack these particular tissues, many possess simpler tissues that are specialized for internal transport of wate
Vascular plant
Vascular plants, also known as tracheophytes and also higher plants, form a large group of plants that are defined as those land plants that have lignified tissues for conducting water and minerals throughout the plant
Gymnosperm
The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term “gymnosperm” comes from the Greek composite word γυμνόσπερμος, meaning “naked seeds
Angiosperm
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approximately 13,164 known genera and c. 295,383 known species
Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms’ activities
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
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers
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
is the growth of an organism which responds to a light stimulus
Asexual Reproduction
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
Toxoplasmosis
a disease caused by toxoplasmas, transmitted chiefly through undercooked meat, or in soil or cat feces
Malaria
A disease caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes
Giardia
An intestinal infection caused by a giardia parasite
