physical rather than biological; not derived from living organisms.
devoid of life; sterile.
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
the diversification of a group of organisms into forms filling different ecological niches.;
the diversification of an ancestral group of organisms into a variety of related forms specialized to fit different environments or ways of life, each often further diversifying into more specialized types.
Anabolic reactions build new molecules and/or store energy.
(1) A type of reproduction in plants where the usual sexual reproduction is replaced by asexual means that does not involve meiosis and syngamy.
(2) Seed production without involving fertilization.
(3) The formation of a new sporophyte but not involving fertilization.
Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction.
Adenosine triphosphate is a nucleoside triphosphate used in cells as a coenzyme, often called the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical energy within cells for metabolism
ATP synthase (EC 220.127.116.11) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms.
A method of asexual reproduction that involves the splitting of a parent cell into two approximately equal parts.
of, relating to, or resulting from living things, especially in their ecological relations.
(of a plant) having or developing buds.
"a budding chrysanthemum"
(of a part of the body) becoming larger as part of the process of normal growth.
(of a person) beginning and showing signs of promise in a particular career or field.
The Calvin cycle (also known as the Calvin-Benson cycle) is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent because it takes place after the energy has been captured from sunlight.
catabolism definition. Biochemical reactions that break down molecules in metabolism. Molecules may be broken down to gain their energy or to prepare them for disposal from the body. (Compare anabolism.)
Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
community, also called biological community, in biology, an interacting group of various species in a common location.
Competitive inhibition is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa.
a measurement of how the concentration of something changes from one place to another.
Consumers are organisms of an ecological food chain that receive energy by consuming other organisms. These organisms are formally referred to as heterotrophs, which include animals, bacteria and fungus.
is the interaction process by which binding of a ligand to one site on a macromolecule (enzyme, receptor, etc.) influences binding at a second site, e.g. between the substrate binding sites of an allosteric enzyme.
Courtship in animals is the behaviour by which different species select their partners for reproduction. Usually, the male starts the courtship, and the female chooses to either mate or reject the male based on his "performance". Many animals have mate-selection courtship rituals.
coloring that conceals or disguises an animal's shape
A plant cuticle is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm. It consists of lipid and hydrocarbon polymers impregnated with wax, and is synthesized exclusively by the epidermal cells.
The synthesis of ATP during photosynthesis, coupled to the cyclic passage of electrons to and from P700, the specialized form of chlorophyll a which is involved in photosystem I, using a series of carrier molecules.
a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
Diffusion is the movement of molecules from a high concentration to a low concentration. Many molecules diffuse across cell membranes.
