An idioblast is an isolated plant cell that differs from neighboring tissues. They have various functions such as storage of reserves, excretory materials, pigments, and minerals. They could contain oil, latex, gum, resin, tannin, or pigments etc.
Cultured meat companies have been putting significant resources into alternative growth media. After the creation of the cell lines, efforts to remove serum from the growth media are key to the advancement of cellular agriculture as fetal bovine serum has been the target of most criticisms of cellular agriculture and cultured meat production.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
False-color Cassini radar mosaic of Titan's north polar region; the blue areas are lakes of liquid hydrocarbons. "The existence of lakes of liquid hydrocarbons on Titan opens up the possibility for solvents and energy sources that are alternatives to those in our biosphere and that might support novel life forms altogether different from those on Earth."—NASA Astrobiology Roadmap 2008 [1]
DistroWatch is a website that provides news, distribution pages hit rankings, and other general information about various Linux distributions as well as other free software/open source Unix-like operating systems. It now contains information on several hundred distributions [1] and a few hundred distributions labeled as active. [2]
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .
The diversity of cell types within any part of a naturally grown plant makes it very difficult to investigate and understand some general biochemical phenomena of living plant cells. The transport of a solute in or out of the cell, for example, is difficult to study because the specialized cells in a multicellular organism behave differently.
This is where the transformed plant tissue are grown repeatedly on agar plates that contain antibiotics like spectinomycin. [5] Only plant cells that have successfully integrated the gene cassette as shown above will be able to express the antibiotic resistance selectable marker and therefore grow normally on agar plates containing antibiotics.
