It is a form of nastic movement, not to be confused with thermotropism, which is a directional response in plants to temperature. A common example of this is in some Rhododendron species, but thermonasty has also been observed in other plants, such as Phryma leptostachya . [ 1 ]
Raunkiær's life-form scheme has subsequently been revised and modified by various authors, [6] [7] [8] but the main structure has survived. Raunkiær's life-form system may be useful in researching the transformations of biotas and the genesis of some groups of phytophagous animals.
Although plants produce numerous copies of the same organ during their lives, not all copies of a particular organ will be identical. There is variation among the parts of a mature plant resulting from the relative position where the organ is produced. For example, along a new branch the leaves may vary in a consistent pattern along the branch.
Plants affected by mosaic disease experienced a decrease in phytolith size. This is because the virus constricts overall plant growth and therefore phytolith growth as well. Contrastingly, plants affected with bacterial wilt disease resulted in much larger phytoliths but they were abnormally shaped. This could be due to the bacteria causing ...

Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds , which can be used by other organisms .
On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens , and these traits are not continuous. The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility , termed heteromorphic self-incompatibility , that is, the pollen from a ...
