Several oblong sacs overlap in parallel, small sac scattered around the big sac. Golgi apparatus involved in the process of cell secretion, the endoplasmic reticulum ribosome synthesis of a variety of proteins processed, classified and packaged, or combined with Golgi apparatus synthesis of glycoprotein glycoprotein transport out of cells for extracellular use, At the same time will also process the classified proteins and lipids synthesized by the endoplasmic reticulum processing, according to the class sent to specific parts of the cell. Golgi apparatus also carries out sugar biosynthesis.
3. Lysosome (lysosome) This organelle was discovered in 1955. Studies using biochemical and electron microscopy have shown that lysosomes are granular structures with sizes generally ranging from 0.25 μm to 0.8 μm, and are actually bound by the resolution of optical microscopy. Surface surrounded by a single film (a unit film), its size, morphology has greatly changed. Which contains a variety of hydrolases, so called lysosomes, is to digest or dissolve substances in the body. At least 60 hydrolases have now been identified, and the characteristic enzyme is acid phosphatase. These enzymes can break down some large molecules (such as proteins, nucleic acids, polysaccharides, lipids and other macromolecules) into smaller molecules for cellular synthesis or mitochondrial oxidation needs. Lysosomes have the main role of dissolution and digestion. It has an important role in the elimination of dead cells in living organisms, in the exclusion of foreign bodies to protect the body, and in embryogenesis and development. The pathological research is also of great significance. For example, when a cell suddenly lacks oxygen or is under the action of some toxin, the lysosomal membrane breaks down in the cell, releasing the enzyme, digesting the cell itself, and also diffusing to other structures outside the cell. Another example is excessive vitamin A can lysosomal membrane rupture, resulting in spontaneous fractures. Based on the above understanding of the role of lysosomes, drugs can be considered to control the lysosomal membrane rupture. For example, drugs that have a stabilizing effect on lysosomal membranes can be used to protect cells under conditions of danger, or drugs that specifically impair the membrane can be used to remove unwanted or even harmful cells Cancer cells, etc.). Artificial lysosomes have been made that function in vitro in the same way as they do in the body.
4. Mitochondrium Mitochondria are linear, small rod-like or granular structures. Blue-green bacteria can be stained with Janus green in living cells. Observed under an electron microscope, the mitochondrial surface is composed of bilayer membranes. The inner membrane forms inwardly some intervals, called the cristae. In the mitochondria rich in enzyme system.

鴕鳥的卵黃直徑可達(dá)5cm,支原體僅0.1μm,人的坐骨神經(jīng)細(xì)胞可長(zhǎng)達(dá)1m。
在真核細(xì)胞的核中,DNA與組蛋白等蛋白質(zhì)共同組成染細(xì)菌體結(jié)構(gòu),在核內(nèi)可看到核仁。在細(xì)胞質(zhì)內(nèi)膜系統(tǒng)很發(fā)達(dá),存在著內(nèi)質(zhì)網(wǎng)、高爾基體、線粒體和溶酶體等細(xì)胞器,分別行使特異的功能。
真核生物包括我們熟悉的動(dòng)植物以及微小的原生動(dòng)物、單細(xì)胞海藻、真菌、苔蘚等。真核細(xì)胞具有一個(gè)或多個(gè)由雙膜包裹的細(xì)胞核,遺傳物質(zhì)包含于核中,并以染細(xì)菌體的形式存在。染細(xì)菌體由少量的組蛋白及某些富含精氨酸和賴氨酸的堿性蛋白質(zhì)構(gòu)成。真核生物進(jìn)行有性繁殖,并進(jìn)行有絲分裂。也有些真核生物的細(xì)胞也能進(jìn)行無(wú)絲分裂,如蛙的紅細(xì)胞,人的肝臟細(xì)胞。在形態(tài)結(jié)構(gòu)方面,一般細(xì)胞都具有細(xì)胞膜、細(xì)胞質(zhì)(包括各種細(xì)胞器)和細(xì)胞核的結(jié)構(gòu)。少數(shù)單細(xì)胞有機(jī)體不具核膜(核物質(zhì)存在于細(xì)胞質(zhì)中的一定區(qū)域),稱為原核細(xì)胞(prokaryotic cell),如藍(lán)細(xì)菌。具核膜的細(xì)胞就是細(xì)胞有真正的細(xì)胞核,稱為真核細(xì)胞(eu-karyotic cell)。
在機(jī)能方面:1.細(xì)胞能夠利用能量和轉(zhuǎn)變能量。例如細(xì)胞能將化學(xué)鍵能轉(zhuǎn)變?yōu)闊崮芎蜋C(jī)械能等,以維持細(xì)胞各種生命活動(dòng);2.具有生物合成的能力,能把小分子的簡(jiǎn)單物質(zhì)合成大分子的復(fù)雜物質(zhì),如合成蛋白質(zhì)、核酸等;3.具有自我復(fù)制和分裂繁殖的能力,如遺傳物質(zhì)的復(fù)制,通過(guò)細(xì)胞分裂將細(xì)胞的特性遺傳給下一代細(xì)胞。此外,還具有協(xié)調(diào)細(xì)胞機(jī)體整體生命的能力等。細(xì)胞是一團(tuán)原生質(zhì)(protoplasm),由它分化出細(xì)胞膜、細(xì)胞核、細(xì)胞質(zhì)和各種細(xì)胞器等(圖1—4)。原生質(zhì)這個(gè)概念一直在沿用著,有人認(rèn)為從分子水平看,原生質(zhì)這個(gè)名稱是籠統(tǒng)的不明確的。[1]
(一)細(xì)胞膜或質(zhì)膜(cell membrane或 plasma membrane, plasmolemma)包圍在細(xì)胞的表面,為極薄的膜。一般在光學(xué)顯微鏡下看不見。不過(guò),在顯微解剖鏡下,如用微針輕輕地壓細(xì)胞的表面,可見細(xì)胞有明顯的皺紋。如果把不能透過(guò)細(xì)胞膜的染料用微吸管注入細(xì)胞,結(jié)果細(xì)胞就變得有顏細(xì)菌,而且只限在質(zhì)膜以內(nèi)。
