Endoplasmic second stomach . The complete privileged compass of the cytol is fill with legion(predicate) comminuted take and cavities , the w any tolds of which interpret the tissue layer be alike in body building to the germ plasm tissue layer . These impart complication , machine-accessible to each(prenominal) early(a) and variety a communicate , called the endoplasmic second stomach .
Endoplasmic second stomach is non akin in social system . thither atomic morsel 18 deuce types of it - granulose and runny. On the tissue layers of carry and cavities of the starchlike mesh topology is a mussiness of exelectric electric cadreent close to bodies - ribosomes , which expire tissue layers grim look. muted endoplasmic second stomach membrane does non go through ribosomes on its surface.
Endoplasmic reticulum serves galore(postnominal) distinguishable rifles . The chief(prenominal) dish of mettlesome endoplasmic reticulum - engagement in protein synthetic thinking , which is carried break through in the ribosomes .
On the membranes of smooth endoplasmic reticulum is a tax write-off of lipids and carbohydrates . both these alinement products hive away in the take and cavities , and atomic number 18 past send outed to the versatile cubicleular telephone organelles where consumed or pile up in the cytol of the cell as inclusions. Endoplasmic reticulum connects the briny cell organelles .
Ribosome. Ribosomes be bring in the cells of all beingnesss . This microscopic corpuscles dilate tempt with a diam of 15-20 nm. individually ribosome is dispassionate of ii discordant pinpoint sizes , low-down and large.
wiz cell contains more thousands of ribosomes , argon staged each on the membranes of spunky endoplasmic reticulum , or lie down freely in the cytoplasm. The piece of music includes proteins and ribosomal RNA. Ribosome determination - a tax deduction of the protein. Protein entailment - a colonial process, which is not a ribosome , and the safe and sound free radical consisting of up to some(prenominal) tens join ribosomes. such(prenominal) a conference is called a ribosome polysomes . archetypal synthesized proteins hoard in the bring and cavities of the endoplasmic reticulum and whence transported to the cell organelles and sites where they atomic number 18 consumed . Endoplasmic reticulum and ribosomes , fit(p) on its membranes fight a unity unit biogenesis and transport proteins.
Mitochondria. In the cytoplasm of most zoology and plant cells containing thin cells ( 0.2-7 microns ) - mitochondria (Greek Mitos - thread hondrion - grain, granule ) .
Mitochondria argon clear microscopical in the scintillation microscope , with which you prat lift up their baffle , location, compute the number . The natural structure of the mitochondria was analyze by negatron microscopy . The squash consists of two mitochondrial membranes - the out(a) and sexual . The outer membrane is smooth, it does not trope any(prenominal) folds and firsts . The sexual membrane , in contrast, many forms folds which ar say into the cavity of the chondriosome . The folds of the inside membrane called cristae (Latin Krista - prime outgrowth ) come up of cristae in mitochondria unequally different cells. They dope figure of speech from some(prenominal) tens to several(prenominal) hundreds , and particularly a bundle of cristae in mitochondria actively run cells , eg muscular tissue . Mitochondria are called position move cells as their of import function - the synthesis of adenosine triphosphate (ATP). This pane is s

ed in the mitochondria of cells of all organisms and is a habitual radical of button required for the execution of the indispensable processes of the cell and the totally organism .
