Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

No single source of influence has central control over an organism's development. [4] Whilst the genetic influence on development is fundamental, causation does not only occur from the bottom up, but also flows ‘downwards’ [12] from more complex levels of organismal organization (e.g., tissue-specific regulation of gene expression).
The term ontogeny has also been used in cell biology to describe the development of various cell types within an organism. [4] Ontogeny is an important field of study in many disciplines, including developmental biology , cell biology , genetics , developmental psychology , developmental cognitive neuroscience , and developmental psychobiology .
The curriculum usually includes a combination of eight courses including electives (such as Biology, Chemistry, Computer and Physics) as well as compulsory subjects (such as Mathematics, English, Urdu, Islamic studies and Pakistan Studies). The total marks for Matric are 1100 divided between 9th and 10th. [19]
Also gastrocoel. The central internal cavity of the gastrula in most animal embryos, fated to develop into the lumen of the digestive tube ; the primitive gut. The archenteron initially has only one open end, known as the blastopore. B birth blastocoel Also blastocoele, blastocele, cleavage cavity, and segmentation cavity. The fluid-filled or yolk -filled cavity that forms in the developing ...
An important class of molecules involved in morphogenesis are transcription factor proteins that determine the fate of cells by interacting with DNA. These can be coded for by master regulatory genes , and either activate or deactivate the transcription of other genes; in turn, these secondary gene products can regulate the expression of still ...
