The Zygnematophyceae, formerly known as the Conjugatophyceae, generally possess two fairly elaborate chloroplasts in each cell, rather than many discoid ones. They reproduce asexually by the development of a septum between the two cell-halves or semi-cells (in unicellular forms, each daughter-cell develops the other semi-cell afresh) and sexually by conjugation, or the fusion of the entire ...
Ophiophagus kaalinga is endemic to the Western Ghats in southwestern India, found in Tamil Nadu, Kerala, Karnataka, Goa, and parts of Maharashtra.Its range extends from the Ashambu hills near Kanyakumari through various mountain ranges, including the Agasthyamalai and Cardamom hills, reaching elevations of about 100 m to 1800 m above sea level.
The king cobra (Ophiophagus hannah) is a species complex of snakes endemic to Asia.With an average of 3.18 to 4 m (10.4 to 13.1 ft) and a record length of 5.85 m (19.2 ft), [2] it is the world's longest venomous snake and among the heaviest.
The genus Ophioglossum has the highest chromosome counts of any known plant. The record holder is Ophioglossum reticulatum, with about 630 pairs of chromosomes (1260 chromosomes per cell). [3] Other measurements have indicated a chromosome number up to 1440 (n = 720). [4] For comparison, humans have 46 chromosomes, consisting of n = 23 pairs.
Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known.
Structure of a plant cell. 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 absence of flagella or ...
Ophiophagy (Greek: ὄφις + φαγία, lit. ' snake eating ') is a specialized form of feeding or alimentary behavior of animals which hunt and eat snakes.There are ophiophagous mammals (such as the skunks and the mongooses), birds (such as snake eagles, the secretarybird, and some hawks), lizards (such as the common collared lizard), and even other snakes, such as the Central and South ...
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...
