Chlorophytes are eukaryotic organisms composed of cells with a variety of coverings or walls, and usually a single green chloroplast in each cell. [4] They are structurally diverse: most groups of chlorophytes are unicellular, such as the earliest-diverging prasinophytes, but in two major classes (Chlorophyceae and Ulvophyceae) there is an evolutionary trend toward various types of complex ...
In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
New World crops are those crops, food and otherwise, that are native to the New World (mostly the Americas) and were not found in the Old World before 1492 AD. Many of these crops are now grown around the world and have often become an integral part of the cuisine of various cultures in the Old World .
Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 22 ] [ 23 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 24 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.
The largest seed in the world is the coco de mer, [1] [2] the seed of a palm tree. [3] It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds).
Millennium Seed Bank building Central visitor hall Bixa orellana seeds Ravenala madagascariensis seeds. The Millennium Seed Bank Partnership (MSBP or MSB), formerly known as the Millennium Seed Bank Project, is the largest ex situ plant conservation programme in the world [1] coordinated by the Royal Botanic Gardens, Kew.
Depending on the species, Chlorophyceae can grow unicellular (e.g. Chlamydomonas), colonial (e.g. Volvox), filamentous (e.g. Ulothrix), or multicellular. [example needed] They are usually green due to the presence of chlorophyll a and chlorophyll b; they can also contain the pigment beta-carotene.
