B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism and synthesis of red blood cells. [ 1][ 2] They are a chemically diverse class of compounds. [ 1] Dietary supplements containing all eight are referred to as a vitamin B complex. Individual B vitamins are referred to by B-number or by chemical name ...
Broccoli is an annual plant which can grow up to 60–90 cm (20–40 in) tall. [ 11] Broccoli is very similar to cauliflower, but unlike it, its floral buds are well-formed and clearly visible. [further explanation needed] The inflorescence grows at the end of a central, thick stem and is dark green. Violet, yellow or even white heads have been ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure. [ 1][ 2 ...
Definition. Phytochemicals are chemicals of plant origin. [ 1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [ 2][ 3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Methylcobalamin (mecobalamin, MeCbl, or MeB 12) is a cobalamin, a form of vitamin B 12. It differs from cyanocobalamin in that the cyano group at the cobalt is replaced with a methyl group. [ 1] Methylcobalamin features an octahedral cobalt (III) centre and can be obtained as bright red crystals. [ 2] From the perspective of coordination ...
Biotin is a water-soluble B vitamin. Consumption of large amounts as a dietary supplement results in absorption, followed by excretion into urine as biotin. Consumption of biotin as part of a normal diet results in urinary excretion of biotin and biotin metabolites.
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 ...
