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 ...
Microtubule-associated protein. In cell biology, microtubule-associated proteins ( MAPs) are proteins that interact with the microtubules of the cellular cytoskeleton. MAPs are integral to the stability of the cell and its internal structures and the transport of components within the cell.
Plant cell structure. Animal cell structure. A vacuole (/ ˈvækjuːoʊl /) is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. [1][2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in ...
Photosystem. Photosystems are functional and structural units of protein complexes involved in photosynthesis. Together they carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons. Photosystems are found in the thylakoid membranes of plants, algae, and cyanobacteria.
Plasmodesma. The structure of a primary plasmodesma. CW= cell wall, CA= callose, PM= plasma membrane, ER= endoplasmic reticulum, DM=desmotubule, Red circles= actin, Purple circles and spokes=other unidentified proteins [1] Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells [2] and some ...
Plant tissue culture. Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer ...
Microtubule organizing center. The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division ...
Plant stem cells are innately undifferentiated cells located in the meristems of plants. [1] Plant stem cells serve as the origin of plant vitality, as they maintain themselves while providing a steady supply of precursor cells to form differentiated tissues and organs in plants. [2][failed verification] Two distinct areas of stem cells are ...
