Term
charophytes and land plants
Definition
a type of lineage of green algae, the closest living relatives of land plants
Term
Mycorrhiza
Definition
Absorbs phosphorus and other essential minerals as well as water and other things
Term
stomata functions
Definition
a pore surrounded by guard cells in the epidermis of a leaf. when open co2 enters, and water and 02 exit.
Term
xylem
Definition
the nonliving portion of a plant's vascular sysem the provides support and conveys the xylem sap form roots to the plant.
Term
phloem
Definition
the portion of a plants vascular tissue system that conveys the sap throug the plant.
Term
bryophytes
Definition
one of a group of plants that lack xylem and phloem, these include mosses liverworts and hornworts.
Term
ferns
Definition
are sporophyte
Term
gametophyte
Definition
the multicellular haploid form in the life cycle of organisms undergoing alternation of generations. produces haploid gametes the unite and grow into the sporophyte generation.
Term
sporophyte
Definition
the multicell diploid form in the life cycle of organisms undergoing slternation of generations. and visa versa about the gametophyte.
Term
fruit
Definition
a ripened thickened ovary of a flower, which protects develping seeds and aids in their dispersal.
Term
angiosperms
Definition
a flowering plant, which forms seeds inside a protective chamber called an ovary.
Term
gymnosperms
Definition
a naked seed plant. its seed is said to be naked because it is not enclosed in an ovary.
Term
fungus digestion
Definition
happens outside of the plant through absorbtion.
Term
hyphae
Definition
one of the many filaaments making up the body of a fungus.
Term
lichen
Definition
A simple plant consisting of a fungus, usually of the subdivision Ascomycotina, that grows symbiotically with algae, forming a low crustlike or branching growth on rocks, walls, and trees.
Term
Flower Parts
Definition
Receptacle: The part of a flower stalk where the parts of the flower are attached.
Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud.
Petal: The parts of a flower that are often conspicuously colored.
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.
Anther: The part of the stamen where pollen is produced.
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.
Stigma: The part of the pistil where pollen germinates.
Ovary: The enlarged basal portion of the pistil where ovules are produced.
Term
autotrophic
Definition
of or relating to organisms (as green plants) that can make complex organic nutritive compounds from simple inorganic sources by photosynthesis
Term
heterotrophic
Definition
requiring organic compounds of carbon and nitrogen for nourishment; "most animals are heterotrophic
Term
ectoderm
Definition
The outermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the epidermis, nerve tissue, and nephridia
Term
mesoderm
Definition
The middle layer of an embryo in early development
Term
endoderm
Definition
The innermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the lining of the gut and associated structures
Term
radial
Definition
arrangement of constituents, especially of radiating parts, about a central point
Term
pentaradial
Definition
type of radial symmetry, characteristic of echinoderms, in which body parts are arranged along five rays of symmetry
Term
bilateral
Definition
Symmetrical arrangement, as of an organism or a body part, along a central axis, so that the body is divided into equivalent right and left halves by only one plane
Term
Hydrostatic skeleton
Definition
consist of fluid-filled closed chambers. Internal pressures generated by muscle contractions cause movement as well as maintain the shape of the animals, such as the sea anemone and worms.
Term
Protostomes
Definition
A multicellular organism whose mouth develops from a primary embryonic opening, such as an annelid or mollusk
Term
Sponges
Definition
A primitive sedentary aquatic invertebrate (phylum Porifera) with a soft porous body that is typically supported by a framework of fibers or calcareous or glassy spicules. Sponges draw in a current of water to extract nutrients and oxygen
Term
Porifera
Definition
A phylum of aquatic invertebrate animals that comprises the sponges
Term
Annelids
Definition
A large phylum that comprises the segmented worms, which include earthworms, lugworms, and leeches
Term
metamorphosis
Definition
in an insect or amphibian) The process of transformation from an immature form to an adult form in two or more distinct stages.
Term
Notochord
Definition
A cartilaginous skeletal rod supporting the body in all embryonic and some adult chordate animals
Term
Tube feet
Definition
One of the numerous external, fluid-filled muscular tubes of echinoderms, such as the starfish or sea urchin, serving as organs of locomotion, food handling, and respiration
Term
Ectothermic
Definition
poikilothermic: of animals except birds and mammals; having body temperature that varies with the environment
Term
endothermic
Definition
Accompanied by or requiring the absorption of heat
Term
Monotremes
Definition
A primitive mammal (order Monotremata, subclass Prototheria) that lays large yolky eggs and has a common opening for the urogenital and digestive systems
Term
rain shadow
Definition
A rain shadow is an area of dry land that lies on the leeward (or downwind) side of a mountain. Winds carry air masses up and over the mountain range and as the air is driven upward over the mountain, falling temperatures cause the air to lose much of its moisture as precipitation.
Term
Tropical rain forest
Definition
are found in equatiorial regions where total rainfall exceeds 250 cm annually. biome is the richist anywhere on earth.
Term
Biomes
Definition
A large naturally occurring community of flora and fauna occupying a major habitat
