plant Flashcards
Protist
an organism that belongs to the kingdom protista.
Heterotroph
an orginism that gets food by eating other orginisms or their byproducts and that cannot make organinc compounds for inorganic materials.
Eukaryote
all products are Eukaryote wich means that their cells each have a nucleaus.
Decomposer
item that breaks items down.
Fungi
eukaryotic heterotrophs that have rigid cell walls and no chlorophyll.
spore
a reproductive cell or multicellular structure that is resistant to stressful enviromental conditions and that can develope into an adult without fusing into another cell.
Nonvascular plant
the three groups of plants (liverworts, hornwarts, and mosses.)that lack specialized conducting tissues and true roots, stems, and leaves.
Vascular plant
a plant that has specialize 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 flowered plant that produces seeds withen a fruit.
Transpiration
the processby which plants release water vapor into the air through stomata.
Tropism
the growth of all or part of an orginism in response to an external stimulas such as light.
Parasite
an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host’s expense.
Host
place were bacteria and protists are at .
Lichen
a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees.
Vascular plant
a plant that is characterized by the presence of conducting tissue.
Photosynthesis
the 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.
Cellular respiration
The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions (see metabolism) of an organism run. Note: The main carrier of energy in metabolism is the molecule ATP.
Gravitropism
s 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 ( positive phototropism ) or away from it ( negative phototropism ).
Asexual Reproduction
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. Symptoms generally pass unremarked in adults, but infection can be dangerous to unborn children.
Malaria
an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells. The parasite is transmitted by mosquitoes in many tropical and subtropical regions.
