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 ...
A cactus (pl.: cacti, cactuses, or less commonly, cactus) [ 3 ] is a member of the plant family Cactaceae (/ kækˈteɪsi.iː, - ˌaɪ /), [ a ] a family comprising about 127 genera with some 1,750 known species of the order Caryophyllales. [ 4 ] The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name ...
The Golgi apparatus (/ ˈɡɒldʒi /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. [ 1 ] Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.
Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. [2] The genetic material is freely found in the cytoplasm. Prokaryotes can carry extrachromosomal DNA elements called plasmids, which are usually circular.
Fouquieria splendens (commonly known as ocotillo / ɒ k ə ˈ t iː j oʊ / (Latin American Spanish:), but also referred to as buggywhip, coachwhip, candlewood, slimwood, desert coral, Jacob's staff, Jacob cactus, and vine cactus) is a plant indigenous to the Mojave Desert, Sonoran Desert, Chihuahuan Desert and Colorado Desert in the Southwestern United States (southern California, southern ...
A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.
Euglena is a genus of single cell flagellate eukaryotes. It is the best known and most widely studied member of the class Euglenoidea, a diverse group containing some 54 genera and at least 200 species. [1][2] Species of Euglena are found in fresh water and salt water. They are often abundant in quiet inland waters where they may bloom in ...
