Celeriac (Apium graveolens Rapaceum Group, synonyms Apium graveolens Celeriac Group and Apium graveolens var. rapaceum), [1] also called celery root, [2] knob celery, [3] and turnip-rooted celery [4] (although it is not a close relative of the turnip), is a group of cultivars of Apium graveolens cultivated for their edible bulb-like hypocotyl, and shoots.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
It starts with cells, which can come from a fertilized egg, a special bank of stored cells or tissue initially taken from a living animal. The cells are mixed with a broth of nutrients that the ...
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 ...
This zone is permeated with infection threads full of bacteria. The plant cells are larger than in the previous zone and cell division is halted. Interzone II–III—Here the bacteria have entered the plant cells, which contain amyloplasts. They elongate and begin terminally differentiating into symbiotic, nitrogen-fixing bacteroids.
The removal of the cell wall of one cell of each type of plant using cellulase enzyme to produce a somatic cell called a protoplast; The cells are then fused using electric shock (electrofusion) or chemical treatment to join the cells and fuse together the nuclei. The resulting fused nucleus is called heterokaryon.
Structure of a typical animal cell Structure of a typical plant cell. Plants, animals, fungi, slime moulds, protozoa, and algae are all eukaryotic. These cells are about fifteen times wider than a typical prokaryote and can be as much as a thousand times greater in volume.
Line of T175 cell culture flasks containing red cell culture medium. In biology, a subculture is either a new cell culture or a microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium. This action is called subculturing or passaging the cells. Subculturing is used to prolong the lifespan and ...
