The corpuscles of Herbst or Herbst corpuscles are nerve-endings similar to the Pacinian corpuscle, found in the mucous membrane of the tongue, in pits on the beak and in other parts of the bodies of birds.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Versuch die Metamorphose der Pflanzen zu erklären, known in English as Metamorphosis of Plants, was published by German poet and philosopher Johann Wolfgang von Goethe in 1790. In this work, Goethe essentially discovered the (serially) homologous nature of leaf organs in plants, from cotyledons , to photosynthetic leaves, to the petals of a ...

A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
Apophysis may refer to: . A tubercle (bone); Apophysis (spider), an outgrowth of the exoskeleton in spiders and other arachnids In botany, an outgrowth or enlargement of an organ such as a plant stem
In evolutionary biology, mimicry in plants is where a plant evolves to resemble another organism physically or chemically. Mimicry in plants has been studied far less than mimicry in animals . It may provide protection against herbivory , or may deceptively encourage mutualists, like pollinators , to provide a service without offering a reward ...
matK is one of the protein-coding genes involved in functions other than photosynthetic reactions (red boxes). matK maps at the 2–3.5 kb coordinates. Maturase K (matK) is a plant plastidial gene. [1] The protein it encodes is an organelle intron maturase, a protein that splices Group II introns. It is essential for in vivo splicing of Group ...
Nutrients from the plant travel through vascular tissue in the funiculus and outer integument through the chalaza into the nucellus. During the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells. Diagram of angiosperm ovule showing location of chalaza
