Diagram of a typical animal cell. Organelles are labelled as follows: Nucleolus; Nucleus; Ribosomes (dots on rough reticulum walls) Vesicle; Rough endoplasmic reticulum; Golgi apparatus (or "Golgi body") Cytoskeleton; Smooth endoplasmic reticulum; Mitochondrion; Vacuole; Cytosol; Lysosome; Centriole; Cell membrane
The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton . The phospholipid membrane encloses the cisternal space (or lumen), which is continuous with the perinuclear space but separate from the cytosol .
Description: The image is a corrected version of an image i made sometime ago. the original quate on the image was "the image describes the parts on a typical plant cell. the image i made myself as resources i used the simple structure here, also the one i found hereand must of the text i could get from here as external source i used another structure found on the book "molecular cell biology ...
The outer nuclear membrane is continuous with the rough endoplasmic reticulum membrane, and like that structure, features ribosomes attached to the surface. The outer membrane is also continuous with the inner nuclear membrane since the two layers are fused together at numerous tiny holes called nuclear pores that perforate the nuclear envelope.
changed the smooth endoplasmic reticulum to look as a part of the rough ER. made ribosome smaller and more attached to the rough endoplasmic reticulum; made small membrane vesicles smaller and yellow. changed Golgi vesicles to Golgi body and added the actual Golgi vesicles. grouped elements that belonged together. made the file an SVG
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.
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 algal cells, enabling transport and communication between ...
Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane-bound organelles. The formation of cellular compartments is called compartmentalization.
