A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [1] [2] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are ...
Monotropa uniflora, an obligate myco-heterotroph known to parasitize fungi belonging to the Russulaceae. [1]Myco-heterotrophy (from Greek μύκης mýkes ' fungus ', ἕτερος héteros ' another ', ' different ' and τροφή trophé ' nutrition ') is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon ...
Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic.
Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction. Growth due to gravitropism is mediated by changes in concentration of the plant hormone auxin within plant cells.
Effect of plant density on (a) total shoot mass and (b) seed mass per unit ground area. Schematised figure, inspired a.o. by experiments with maize by Li et al. (2015). Many of the processes related to plant density can well be studied in monocultures of even-aged individuals that are sown or planted at the same time. These can be referred to ...
When the density is defined in proportion to energy contents, nutrient-dense foods such as meats, fruits and vegetables are the opposite of energy-dense food (also called "empty calorie" food), such as alcohol and foods high in added sugar or processed cereals.
Saprotrophic nutrition / s æ p r ə ˈ t r ɒ f ɪ k,-p r oʊ-/ [1] or lysotrophic nutrition [2] [3] is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter.
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
