Carthamus tinctorius (safflower) belongs to family Asteraceae.The asterfamily(Asteraceae) is one of the largest angiospermfamilies, with more than 1,620 genera and 23,600 species of herbaceous plants, shrubs, and trees distributed throughout the world. The plants are characterized by their composite flower heads and one-seeded achene fruits.

WiltingThe condition that arises in plants when more water is lost by evaporation than is absorbed from the soil. This causes the cells to lose theirturgorand the plant structure droops. Plants can normally recover from wilting if water is added to the soil, but permanent wilting and possible death can result if the plant does not have access to water for a long period of time. In certain plants wilting is important as a mechanism to avoid overheating: when the leaves droop they are taken out of direct contact with the sun's rays. When the sun sets the plant can begin to transpire at the normal rate and the cells of the leaves regain their turgor.

Xylem is responsible for transport of water. If xylem is blocked, plant will undergo wilting

The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteenfacial skeletonbones. In the neurocranium these are theoccipital bone, twotemporal bones, twoparietal bones, thesphenoid,ethmoidandfrontal bones.

Pulmonary surfactant is a mixture of lipids and proteins which is secreted by the epithelial type II cells into the alveolar space. Its main function is to reduce the surface tensionat the air/liquid interface in the lung.

Kreb cycle doesn't occurs in mitochondria in E.coli beacuseE.coli are prokaryotes.

Crassulacean acid metabolism, also known asCAMphotosynthesis, is a carbon fixation pathway that evolved in someplantsas an adaptation to arid conditions. In aplantusing fullCAM, thestomatain the leaves remain shut during the day to reduce evapotranspiration, butopenat night to collect carbon dioxide (CO₂).

During muscle contraction, both I-band and H-zone progressively shorten and eventually disappear while length of A-band remains constant.

Photosynthesis and transpiration both are equally essential processes because photosynthesis helps to maintain the equilibrium position of O₂ and CO₂ in the atmosphere and transpiration maintains the atmospheric temperature.

Leucocytes are called true cells because they possess nucleusunlike RBC where nucleus are absent.

Capitulum is the most advanced type of inflorescence. It is the characteristic of family Compositae. In this inflorescence peduncle is flattened to form receptacle that bears centripetally arranged small sessile flowers called florets surrounded by involucre of bracts, eg., marigold, sunflower etc.
