Classroom Project Work

HeLa Cells (Human Cancer cells)
Доброго времени суток, дорогие друзья. На этом уроке мы подробно познакомимся с структурой человеческой клетки с помощью макета клетки, которую вы сами сделаете на уроке. Just to help you want to post some of the organelles and related functions. Enjoy!
  1. The cell membrane is a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment.
  2. The lysosomes are the cell’s “garbage disposal.” In plant cells, the digestive processes take place in vacuoles. Enzymes within the lysosomes aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, and even worn-out organelles.
  3. The peroxisomes are small, round organelle that contains hydrogen peroxide, oxidises fatty acids and amino acids, and detoxifies many poisons.
  4. The Golgi Apparatus is an eukaryotic organelle made up of a series of stacked membranes that sorts, tags, and packages lipids and proteins for distribution. Cells that engage in a great deal of secretory activity have an abundance of Golgi. Lysosomes are created by the budding of the membranes of the Golgi.
  5. The Rough Endoplasmic Reticulum (RER) is a region of the endoplasmic reticulum that is studded with ribosomes and engages in protein modification and phospholipid synthesis.
  6. The Smooth Endoplasmic Reticulum (SER) is a region of the endoplasmic reticulum that has few or no ribosomes on its cytoplasmic surface and synthesises carbohydrates, lipids, and steroid hormones; detoxifies certain chemicals (like pesticides, preservatives, medications, and environmental pollutants), and stores calcium ions.
  7. The mitochondria. Eukaryotic cells may contain anywhere from one to several thousand mitochondria, depending on the cell’s level of energy consumption. In addition to the aerobic generation of ATP, mitochondria have several other metabolic functions: to generate clusters of iron and sulfur that are important cofactors of many enzymes.
  8. The ribosomes are organelles where protein synthesis takes place.
  9. The nucleus is a cell organelle that houses the cell’s DNA and directs the synthesis of ribosomes and proteins
  10. The centrioles are the cylinders of nine triplets of microtubules each. Centrioles appear to have some role in pulling the duplicated chromosomes to opposite ends of the dividing cell. However, the exact function of the centrioles in cell division isn’t clear, because cells that have had the centrioles removed can still divide; and plant cells, which lack centrosomes, are capable of cell division.
