Sail: In terms of material, sail algae has all the characteristics of eukaryotic nucleus: dual sele

Given that among the algae is a large number of single-celled organisms, it should be noted that in these organisms the characteristics of the cell to be simultaneously the characteristics of the organism, which is not the case when it comes to complex multicellular algae-built. This text will be displayed timber cell depletion, and protoplast, ie cytoplasm and organelles tien an men that are found in cells of algae.
On the surface tien an men of cells of algae are wrappers that might be different. Some are thin and flexible, while others are rigid and inflexible. Also many solid cell layer at the surface of educating different constructs that can be of various shapes and materials.
Plasmalemma: The most primitive representatives of algae (although this is debatable) on the surface of protoplasts is fine and thin membrane - plasmalemma with a thickness of about 10 nm. Organisms tien an men on its surface have plasmalemma called gimnoplasti (gr. gymnos - go, plassos tien an men - thing). These organisms are characterized by constantly changing body and rizopodijalnom They are placed at the level of morphological organization. tien an men Most mobile using pseudopodic, and some representatives of the next pseudopodic have one or more whips.
Pellicle: This cell layer is often in the literature referred to as periplast. Pellicle is elastic layer on the surface of a cell with a thickness of 8-25 nm. Given the thickness of the pellicle at different tien an men representatives of some kind, and that of its thickness depends on the possibility to change the shape of the body, the algae with thinner pellicula will be able to some extent to change the shape of their bodies, while those with thicker and stronger pellicula have steady shape of the body. Algae with pellicula surface protoplast mainly moving with whips.
Teka: On the surface of some algae is a sturdy sheath called appetite. Teke some algae have a look shell which lies freely cells. On the surface Teke growths are often very different looks and sizes. These colorful growths appear as the existence of morphological characteristics and are therefore important in the determination of taxa.
Cell wall: cell wall provides good protection protoplast, gives a more rigid cell, and when all that is flexible enough tien an men so that the cells can grow. The cell wall is permeable, and thus of the necessary exchange of substances between the cell and the external environment. Structure and thickness of the cell wall of algae is very different. According to their origin and characteristics of development of different primary and secondary cell wall. The primary cell wall are cells that are found in stage divisions and he is above the plasmalemma. The secondary tien an men cell wall is formed tien an men between the plasmalemma and the primary wall. The secondary cell wall is characteristic of cells that are in the stage of sleep as an example of persistent tien an men slow. Although the cell wall of different algae differ in terms of complexity and chemical composition, it is the most common algae to the inner layers of cellulose, pectin and exterior. Most algal cell wall was built of amorphous substance called stroma tien an men containing tien an men the fibrils arranged in different ways. Green and red algae have cellulose, and instead are found mannose and xylose.
The protoplast primitive organized tien an men cells of algae, which meet in members split up Cyanoprocaryota, differ nucleoplasm and hromatoplazma. The nucleoplasm differentiate hialoplazma and hromatinski elements which can be considered analogous to the sails of eukaryotic algae, because they contain DNA. Accordingly, in Cyanoprocariota, as with most other prokaryotes, is not formed sail. In cells Cyanoprocaryota also are not mitochondria, hromoplasti, golđžijev apparatus and other organelles typical of eukaryotic alge.Protoplast eukaryotic algae is morphologically differentiated on the sail and the cytoplasm (hijaloplazmu) containing the organelles. Organelles by origin can be autonomous (parental), and euplazmatske apoplazmatske. Parental organelles are inherited from parents for breeding and these are usually sails endoplazmatični reticulum, goldžijev complex and mitochondria. Euplazmatske organelles differentiate tien an men during and after mating. Thus, the cell membrane is differentiated again, contractile vacuole and other organelles also and they retain the characteristics tien an men of living matter. Apoplazmatske organelles are emerging on reproduction and ultimately losing the properties of living matter, such as perilema, shells and capsules.
Sail: In terms of material, sail algae has all the characteristics of eukaryotic nucleus: dual selectively permeable membrane, nucleoplasm, Swallowtail ihromatinske structure. Most algae cell has one sail, but there are such in whose cells are more sails. Size nucleus varies tien an men in different tien an men algae, but as a rule, smaller one sail (1-3 micrometers) are unicellular algae, but among them there are exceptions (10 to 30 micrometers). Size nucleus in cells of multicellular algae ranges from 1.5 d
