Protist, plant, and fungi Flashcards
Protist
An organism that belongs to the kingdom Protista.
Heterotroph
Organism that gets food by eating other organisms or their byproducts and that cant make organic compounds from inorganic materials.
Eukaryote
Means that the cell has a nucleus.
Decomposer
Get energy from breaking down dead organic matter.
Parasite
Organism that feeds on an organism of another species and that usually harms the host; the host never benefits from the presence of the parasite.
Host
Organism from which a parasite takes food or shelter.
Fungi
Organism whose cells have nuclei, rigid cell walls, and no chlorophyll and that belongs to the kingdom fungi.
Spore
A reproductive cell or multi cellular 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 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, necks, and stems.
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 a fruit.
Angiosperm
A flowering plant that produces seeds within a fruit.
Photosynthesis
Plants use energy from sunlight to make food from carbon dioxide and water.
Cellular respiration
The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions
Transpiration
the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
Tropism
the turning of all or part of an organism in a particular direction in response to an external stimulus.
Gravitropism
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
Asexual reprodection
A form of reproduction that does not involve meiosis, ploidy reduction or fertilization, and the offspring is a clone of the parent organism;because of no exchange of genetic material. Supplement. An organism capable of asexual reproduction is able to produce offspring in the absence of a mate.
Toxoplasmosis
transmitted to humans by consumption of insufficiently cooked meat containing the parasite or by contact with contaminated cats or their feces
Malaria
infectious disease caused by protozoan parasites from the Plasmodium family that can be transmitted by the bite of the Anopheles mosquito or by a contaminated needle or transfusion
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.
