Green bean. A pile of raw green beans. Green beans are young, unripe fruits of various cultivars of the common bean ( Phaseolus vulgaris ), [1] [2] although immature or young pods of the runner bean ( Phaseolus coccineus ), yardlong bean ( Vigna unguiculata subsp. sesquipedalis ), and hyacinth bean ( Lablab purpureus) are used in a similar way.

Ecology Phaseolus species are used as food plants by the larvae of some Lepidoptera species, including common swift, garden dart, ghost moth Hypercompe albicornis, H. icasia and the nutmeg. Etymology The generic name Phaseolus was introduced by Linnaeus in 1753, from the Latin phaseolus, a diminutive of phasēlus, in turn borrowed from Greek φάσηλος / phasēlos of unknown origin.
Structure. In insects, polytene chromosomes are commonly found in the salivary glands; they are also referred to as "salivary gland chromosomes". The large size of the chromosome is due to the presence of many longitudinal strands called chromonemata; hence the name polytene (many stranded). They are about 0.5 mm in length and 20 μm in diameter.
Phaseolus acutifolius, also known as the tepary bean, is a legume native to the southwestern United States and Mexico and has been grown there by the native peoples since pre-Columbian times. It is more drought-resistant than the common bean ( Phaseolus vulgaris ) and is grown in desert and semi-desert conditions from Arizona through Mexico to Costa Rica .
For example, diploid human cells contain 23 pairs of chromosomes including 1 pair of sex chromosomes (46 total), half of maternal origin and half of paternal origin. Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes.
