Eukaryotic Educational Materials

Eukaryotic Eukaryotic cells are cells that have system sendomembrane. Cells of this type structurally have a number of organelles in the cytoplasm. These organelles have functions very distinctive, related to each other and play a role important for supporting cell function. Organisms that have types These cells include animals, plants and fungi, both multicellular or unicellular. Eukaryotic cells that enter Unicellular groups namely Yeast, amoeba and Protozoa meanwhile Those belonging to the multicellular group are animals and plants organized. Eukaryotic cell types in plants are slightly different from in animals. In animal cells, it is not found on the outside of the cell the presence of cell walls, on the contrary in plants and fungi cell walls were found. However the cell wall Plant and fungal cells are chemically different in composition. On Chitin is dominated by fungi, whereas in plants it is cellulose. In plants, it is found that there are chloroplast organelles in cellulose plants. In plants, organelles are found chloroplasts whereas in fungi and animals they are not found. Besides These differences are basically both animal, plant and cell cells mushrooms have a similar structure. Animal cells have an endomembrane system so this type of cell is foundvarious organelles in the cytoplasm. In the picture you can see the organelles Golgi apparatus (Golgi apparatus), ER (rough and smooth), microbodies), additionally are visible the mitochondria,and peroxisomes (part of presence of ribosomes, centrioles and cytoskeleton which play a roleimportant in cells. Plants have an endomembrane system in cells This type is found in various organelles in its cytoplasm. On The picture shows the chloroplast organelle, found only in plants, in addition to similar organelles found in animal cells. Besides that It appears that there are several parts of the cell that only belong to plants such as: cell walls and plasmodesmata. 1. Cell Membrane Cell membranes are composed of lipoproteins. The cell membrane limitsall the activities that occur in the cell are not easydisturbed by outside influences. Due to this function, the membranecells are 'selectively permeable', able to detect materialsOnly certain things can enter and leave the cell. 2. Cytoplasm It is a substance found between the cell nucleus and plasma membrane. The cytoplasmic substance is permanent and Playing an active role in metabolic processes are called organelles. Organelles consist of: endoplasmic reticulum, Golgi complex, mitochondria, chloroplasts (only for plants), lysosomes, and bodies Microorganisms are groups of organelles surrounded by membrane, while other organelles are not surrounded by Membranes include ribosomes and centrioles. 3. Endoplasmic Reticulum (ER) The endoplasmic reticulum is a lipoprotein membrane in the cytoplasm which is found between the nuclear membrane and the membrane cytoplasm. There are two types of RE. Ganular RE (rough ER) if on The surface of the ER membrane attaches to ribosomes. RE smooth or non granular if there are no ribosomes on the ER membrane. Organelle function This further processes proteins, lipids or other materials will be secreted so that the resulting product is in accordance with his needs. 4. Golgi body It is an organelles associated with the excretory function of cells, and This structure can be seen using a light microscope normal. This organelle is found in many body organs carry out excretory functions, for example the kidneys. Golgi bodies function produces secretions in the form of sap granules, primary lysosomes, stores proteins and enzymes to be secreted. On cells Golgi bodies in plants are called dictyosomes. 5. Lysosomes are found in animal cells, they are shaped like balls and the diameter is approximately 500nm. Lysosomes ingredients enters cells either by contain enzymes that function to pinositis (food in the form of digest food liquid) or by phagocytosis (eating solids) 6. Ribosomes are an important component in cells. The size ranges from 20-25 nm. Ribosomes are composed of RNA and Proteins consist of large subunits and small subunits. Large sub unit and small subunits will join together when the ribosome is running Its function is protein synthesis. When protein synthesis is complete then the large sub-unit and small sub-unit will separate again.
