(Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. 2. Draw a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function. 3. Describe the difference between the animal and plant cells. Plant Cells have cell walls‚ which makes them appear rectangular

Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are

Tour of the Cell CellsTissuesOrgansOrgan SystemsOrganisms *Cells are made up of smaller functional parts known as cell organelles (little organs). Cell organelles are specialized cell structures that perform specialized jobs in the cell.* 1. Cytoplasm- *Jelly-like substance inside of the cell 2. Mitochondria- *In cellular respiration oxygen is used to extract energy from sugars‚ fats‚ and other nutrients 3. Cell membrane- *It is a selectively permeable membrane 4. Nucleus-

Animal Cell There are two types of cells that exist. Prokaryotic cells are simple cells that have few organelles. These cells don’t have a nucleus‚ but do have DNA. The DNA acts as a sort of “blueprint” for growth and reproduction in the cell. Prokaryotes are things like Bacteria. Eukaryotic cells are a lot more complex than a prokaryotic cell. These cells are able to convert food to energy‚ break down waste products‚ digest food‚ and assist with reproduction of new cells. Eukaryotic cells are in

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

The cell wall is the tough‚ flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength. The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances

which he called cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields.

Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The main function of cellular respiration is to generate ATP for cellular work; it is the process of harvesting chemical energy from organic fuel and converting it to ATP energy. The three stages of cell respiration include: Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis

DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried‚ weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus.  Specimen tubes with stoppers x6  1cm3 diameter cork borer  razor
