The rhombic lip can be divided into eight structural units based on rhombomeres 1-8 (r1-r8), which can be recognized at early stages of hindbrain development. [2] Producing granule cells and five brainstem nuclei, the rhombic lip plays an important role in developing a complex cerebellar neural system. [3] Rhombic lips
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
Syzygium myrtifolium, the red lip or kelat oil, is a species of flowering plant in the family Myrtaceae. [2] It is native to Bangladesh, Myanmar, Thailand, Peninsular Malaysia , Sumatra , Java , Borneo , and the Philippines. [ 1 ]
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [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.
Showy lady slipper (Cypripedium reginae) has a pink labellum P: Petalum S: Sepalum L: Labellum In botany, the labellum (or lip) is the part of the flower of an orchid or Canna, or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them.
Jasmonate (JA) and its derivatives are lipid-based plant hormones that regulate a wide range of processes in plants, ranging from growth and photosynthesis to reproductive development. In particular, JAs are critical for plant defense against herbivory and plant responses to poor environmental conditions and other kinds of abiotic and biotic ...
