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 ...
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
Aspergillus wentii was first described by German mycologist Carl Friedrich Wilhelm Wehmer in 1896. [3] Following a morphology-based classification scheme he created in 1901, Wehmer grouped A. wentii under a category of large Aspergilli that he called the "Macroaspergilli" due to its large fruiting body structure (the conidial head).

The Golgi apparatus (/ ˈ ɡ ɒ l dʒ i /), 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.
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall. [1]It is also called hydrostatic pressure, and is defined as the pressure in a fluid measured at a certain point within itself when at equilibrium. [2]
Axoplasm is the cytoplasm within the axon of a neuron (nerve cell). For some neuronal types this can be more than 99% of the total cytoplasm. [1]Axoplasm has a different composition of organelles and other materials than that found in the neuron's cell body or dendrites.
Entamoeba gingivalis from aggressive periodontal disease patient biofilm using phase contrast microscope 1000x. It is recognizable through its dense core in the middle, formed by a central point encircled by a circular halo and surrounded by bigger phagosomes inside a greyish cytoplasm.
