The pedicels attaching the flowers to the main stem are 0.5–1 millimeters and the flowers resemble a pink, reddish-purple, or purple (rarely white) head of an elephant to a remarkable extent. [ 4 ] [ 9 ] In addition to reflecting visible light, the petals of the flowers also reflect ultraviolet light. [ 7 ]
Light-dependent reactions of photosynthesis at the thylakoid membrane. Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI).
African elephant heads are completely rounded and large, while Asian elephant heads form two hills or humps on the top, with a line down the center of their face. African Elephant vs. Asian ...
When comparing an elephant's vocal folds to those of a human, an elephant's are longer, thicker, and have a larger cross-sectional area. In addition, they are tilted at 45 degrees and positioned more anteriorly than a human's vocal folds. [18] From various experiments, the elephant larynx is shown to produce various and complex vibratory phenomena.
An elephant's skin is generally very tough, at 2.5 cm (1 in) thick on the back and parts of the head. The skin around the mouth, anus , and inside of the ear is considerably thinner. Elephants are typically grey, but African elephants look brown or reddish after rolling in coloured mud.
They are curved forward and continue to grow throughout the elephant's lifetime. [28] Molar of Loxodonta africana, showing lozenge/loxodont. The dental formula of elephants is 1.0.3.3 0.0.3.3 × 2 = 26. [25] Elephants have four molars; each weighs about 5 kg (11 lb) and measures about 30 cm (12 in) long. As the front pair wears down and drops ...
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the hydrogen carrier NADPH and the energy-storage molecule ATP. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant , one of two extant species of African elephant .
