![]() ![]() Discrete elements of information are represented in a digital system by physical quantities called signal which have only two discrete values and are said to be binary. Ihab TalkhanĮarly digital computers were used mostly for numeric computations, in this case the discrete elements used were the digits, from which the term digital computer has emerged. 10 decimal digits, the 26 letters of the alphabet, 25 playing cards, and other discrete quantities. Digital system has a property of manipulating discrete elements of information, discrete information is contained in any set that is restricted to a finite number of elements, e.g. Ihab Talkhanġ4 Important Notes Various binary systems suitable for representing information in digital components.

Because cannabis is a dioecious plant, female or male reproductive organs generally appear on different plants (though cannabis may also develop both on the same plant). ![]() The primary function of anthers is to produce, store, and deliver pollen. It takes time for the cannabis plant to mature and form anthers, and cultivators typically must wait 3-6 weeks before a young, vegetative plant begins to form sex organs. What do anthers look like?Īnthers are long, oval-shaped sacs that come to a point, hence the nickname “bananas.” A plant may produce several anthers near the center of the flower, and they may be a range of colors, including yellow, green, and red. If a cannabis breeder finds that a female plant begins to form anthers, it is typically removed from the other female plants as quickly as possible to avoid pollinating other plants, which would result in seeded buds. These cannabis plants, called hermaphrodites, develop both stamens and female pistils. Due to their long shape, they are sometimes called “bananas.” Male cannabis plants develop anthers, though these pollen sacs may also appear on female plants, often after being exposed to environmental stress or due to genetics. “I took the pollen from the anthers of the OG Kush male.” What is an anther?Īn anther refers to the sac at the end of a stamen which produces, stores, and releases pollen. “I could tell I had a male plant based on the formation of anthers.” ![]()
