plants, fungi, and protist Flashcards
an organism that belongs to the kingdom Protista.
Protist
An organism that gets food by eating other organisms
heterotroph
an organism that feeds on an organism of another species.
parasite
an organism from which a parasite takes food or shelter
host
eukaryotic organisms that convert the suns energy into food.
algae
the microscopic photosynthetic organisms that float near the surface of marine or fresh water.
phytoplankton
an organism whose cells have nuclei, rigid cell walls, and no chlorophyll.
fungus
a non-reproductive filament of a fungus
hypha
The mass of fungal filaments, or hyphae, that forms the body of a fungus
myceliuym
a reproductive cell or multi-cellular structure that is resistant to stressful environmental conditions.
spore
a fungus that looks like wool or cotton
mold
a mass fungal and algal cells that grow together in a symbiotic relationship and that are usually found on rocks and trees
lichen
organisms that break down dead or decaying organisms, and in doing so they carry out the natural process of decomposition.
decomposer
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
eukaryote
lack these particular tissues, many possess simpler tissues that are specialized for internal transport of water.
nonvascular plant
Any of various plants that have the vascular tissues xylem and phloem.
vascular plant
are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and Gnetales.
gymnosperms
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
he 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
is what cells do to break up sugars into a form that the cell can use as energy
cellular respiration
is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
transpiration
the turning of all or part of an organism in a particular direction in response to an external stimulus.
tropism
is a turning or growth movement by a plant or fungus in response to gravity
gravitropism
the orientation of a plant or other organism in response to light, either toward the source of light
phototropism
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
is a mosquito-borne disease caused by a parasite.
malaria
a microscopic parasite that causes the diarrheal illness
giardia
