Persistence is the retention of plant organs, such as flowers, seeds, or leaves, after their normal function has been completed, in contrast with the shedding of deciduous organs after their purpose has been fulfilled. [1] Absence or presence of persistent plant organs can be a helpful clue in plant identification, and may be one of many types ...
Then these plants may either be consumed by humans or other animals. These consumers ingest the chemical and begin metabolizing the toxicant, accumulating more through ingestion, and posing health risks to the organism, their offspring, and any predators.
Depending on the way they are transmitted, plant viruses are classified as non-persistent, semi-persistent and persistent. In non-persistent transmission, viruses become attached to the distal tip of the stylet of the insect and on the next plant it feeds on, it inoculates it with the virus. [ 6 ]
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe. [2] [3]
annual: a plant species that completes its life cycle within a single year or growing season; basal: attached close to the base (of a plant or an evolutionary tree diagram) climber: a vine that leans on, twines around or clings to other plants for vertical support; deciduous: falling seasonally, as with bark, leaves or petals
Phytosociology, also known as phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together. Phytosociology aims to empirically describe the vegetative environment of a given territory.
Native plants can also help prevent water runoff, reduce erosion, improve air quality, allow for less pollution due to less need for mowing by replacing grass lawns with native beds.
Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [clarification needed] Differences in growth were detected early in ontogeny. The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by ...
