The cell membrane is a protective barrier that encloses a cell. • The cell membrane is the outermost structure in cells that lack a cell wall. In cells that have a cell wall, the cell membrane lies just inside the cell wall. • The cell membrane contains proteins, lipids, and phospholipids. • Lipids are a group of compounds that do not dissolve in water. Lipids are “water fearing” or hydrophobic. • Phospholipids are lipids that contain phosphorus. The phosphorus containing ends of phospholipids are “water loving” or hydrophilic. Cell Membrane • All cells have cell membranes. The cell membrane is a protective barrier that encloses a cell. • The cell membrane is the outermost structure in cells that lack a cell wall. In cells that have a cell wall, the cell membrane lies just inside the cell wall. •Todas las células tienen membranas celulares. La membrana celular es una barrera protectora que encierra una célula. La membrana celular es la estructura más externa en las células que carecen de una pared celular. En las células que tienen una pared celular, la membrana celular se encuentra justo dentro de la pared celular. •Todas as células têm membranas celulares. A membrana da célula é uma barreira protectora que envolve uma célula. A membrana da célula é a estrutura externa em células que não possuem uma parede celular. Nas células que têm uma parede celular, a membrana celular situa-se no interior da parede da célula. • Minden sejt van a sejtmembránon. A sejt membrán egy olyan védőgátat, amely magába zár egy cella. A sejt membrán a legkülső szerkezet sejtekben hogy hiányzik egy sejtfal. Azokban a sejtekben, amelyek egy sejtfalat, a sejt membrán fekszik csak belül a sejtfal. Cell Membrane, continued • The cell membrane is made of two layers of phospholipids. It allows nutrients to enter and wastes to exit the cell. Cell Wall • Some eukaryotic cells have cell walls. A cell wall is a rigid structure that gives support to a cell. The cell wall is the outermost structure of a cell. • Plants and algae have cell walls made of a complex sugar called cellulose. The cell walls of plant cells help plants retain their shape. Cell Wall • Some eukaryotic cells have cell walls. A cell wall is a rigid structure that gives support to a cell. The cell wall is the outermost structure of a cell. •Algunas células eucariotas tienen paredes celulares. Una pared celular es una estructura rígida que da apoyo a una célula. La pared celular es la estructura más externa de una célula. •Algumas células eucarióticas têm paredes celulares. Uma parede de célula é uma estrutura rígida que dá apoio a uma célula. A parede da célula é a estrutura mais exterior de uma célula. •Néhány eukarióta sejtek sejtfalakat. Egy cella falon van egy merev szerkezet, amely támogatást nyújt a sejt. A sejtfal a legkülső sejt szerkezetének. Cytoskeleton • The cytoskeleton is a web of proteins in the cytoplasm. It acts as both a muscle and a skeleton. • The cytoskeleton keeps the cell’s membranes from collapsing and helps some cells move. • The cytoskeleton is made of three types of protein. One protein is a hollow tube and the other two are long, stringy fibers. Cytoskeleton • The cytoskeleton is a web of proteins in the cytoplasm. It acts as both a muscle and a skeleton. •El citoesqueleto es una red de proteínas en el citoplasma. Actúa como un músculo y un esqueleto. •O citoesqueleto é uma teia de proteínas no citoplasma. Ele actua tanto como um músculo e um esqueleto. •A citoszkeleton egy webes fehérjék a citoplazmában. Úgy viselkedik, mint a két izom és egy csontváz. Nucleus • The nucleus is a membrane-bound organelle that contains the cell’s DNA. DNA contains the information on how to make a cell’s proteins. • Messages for how to make proteins are copied from the DNA. These messages are then sent out of the nucleus through the membranes. • The nucleus is covered by two membranes. Materials cross this double membrane through pores. Nucleus • The nucleus is a membrane-bound organelle that contains the cell’s DNA. DNA contains the information on how to make a cell’s proteins. •El núcleo es un orgánulo unido a la membrana que contiene el ADN de la célula. ADN contiene la información sobre cómo hacer que las proteínas de una célula. •O núcleo é um organelo ligado à membrana que contém o ADN da célula. DNA contém a informação sobre a forma de fazer proteínas de uma célula. •A sejtmag egy membránhoz kötött organelle, amely tartalmazza a sejt DNS-ébe. DNS információkat tartalmazza, hogyan lehet a sejt fehérje. Ribosomes • Organelles that make proteins are called ribosomes. Unlike most organelles, ribosomes are not covered by a membrane. • Proteins are made of organic molecules called amino acids. All cells need proteins to live. All cells have ribosomes. Ribosomes • Organelles that make proteins are called ribosomes. Unlike most organelles, ribosomes are not covered by a membrane. •Orgánulos que hacen que las proteínas se llaman ribosomas. A diferencia de la mayoría de los orgánulos, los ribosomas no están cubiertos por una membrana. •Organelas que tornam as proteínas são chamados ribossomas. Diferente da maioria das organelas, ribossomos não estão cobertas por uma membrana. •Sejtszervekbe amelyek fehérjéket nevezik riboszómák. Ellentétben a legtöbb sejtszervekbe, riboszómák nem terjed ki a membránt. Endoplasmic Reticulum • The endoplasmic reticulum (ER) is a system of folded membranes in which proteins, lipids, and other materials are made. • The ER is part of the internal delivery system of the cell. Substances move through the ER to different places in the cell. Endoplasmic Reticulum • The endoplasmic reticulum (ER) is a system of folded membranes in which proteins, lipids, and other materials are made. • The ER is part of the internal delivery system of the cell. Substances move through the ER to different places in the cell. Endoplasmic Reticulum, continued • Endoplasmic reticulum is either rough ER or smooth ER. The part of the ER covered in ribosomes is rough ER. ER that lacks ribosomes is smooth ER. Mitochondria • A mitochondrion is the organelle in which sugar is broken down to produce energy. Mitochondria are the main power source of a cell. Chloroplasts • Chloroplasts are organelles in plant and algae cells in which photosynthesis takes place. Photosynthesis is the process by which plants and algae use sunlight, carbon dioxide, and water to make sugar and oxygen. Golgi Complex • The organelle that packages and distributes proteins is called the Golgi complex. The Golgi complex modifies lipids and proteins to do different jobs. Cell Compartments • The bubble that forms from the Golgi complex membrane is a vesicle. A vesicle is a small sac that surrounds material to be moved into or out of cell. • Vesicles also move material within a cell. Vesicles carry new proteins from the ER to the Golgi complex. Other vesicles distribute material from the Golgi complex to other parts of the cell. Cellular Digestion • Lysosomes are vesicles found mainly in animal cells that are responsible for digestion inside a cell. Lysosomes are organelles that contain digestive enzymes. • Lysosomes destroy worn-out or damaged organelles, get rid of waste materials, and protect the cell from foreign invaders. Cellular Digestion, continued • Vacuoles are vesicles. • In plant and fungal cells, some vacuoles act like lysosomes. The large central vacuole in plant cells stores water and other liquids.
