The TIGER domain is a minor membraneless organelle in which messenger RNA (mRNA) encodes certain types of proteins to find the appropriate environment for growth. It is closely associated with the endoplasmic reticulum during protein synthesis .
Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

Tyrode's solution is a solution that is roughly isotonic with interstitial fluid and used in physiological experiments and tissue culture. It resembles lactated Ringer's solution , but contains magnesium , a sugar (usually glucose ) as an energy source and uses bicarbonate and phosphate as a buffer instead of lactate .
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 cells themselves can either be derived from homogenized tissue or from heterogenous cell solutions. Suspension cell culture is commonly used to culture nonadhesive cell lines like hematopoietic cells, plant cells, and insect cells. [1] While some cell lines are cultured in suspension, the majority of commercially available mammalian cell ...
Tissue culture is used in creating genetically modified plants, as it allows scientists to introduce DNA changes to plant tissue via Agrobacterium tumefaciens or a gene gun and then generate a full plant from these modified cells. [11] Tissue cultures are commonly used in plant propagation.
A microorganism, or microbe, [a] is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
Sunflower sea star regenerates its arms. Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.
