that play different roles. A cell is microscopic that has organelles‚ and a city has different services. Keeping them both running smoothly and orderly. As a result they both survive and grow. There’re a lot of different organelles in a cell that are similar to a city for example the cell membrane borders and protects the cell it’s role is letting certain things in and out of the cell in the same way a border in a city does. Another organelle is the vacuole which stores water for later use like a

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

Class IX: Biology Chapter 5: The fundamental unit of life. Chapter Notes Key learnings: 1) In 1665‚ Robert Hooke first discovered and named the cells. 2) Cell is the structural and functional unit of all living organisms. 3) Organisms may be unicellular or multicellular. A single cell constitutes the unicellular organism whereas many cells coordinately function in case of multicellular organism. 4) The size‚ shape and volume of the cell are related to the specific function that they

the spindle fibers towards the poles. Eventually‚ during telophase the fibers disappear and the cell has been stretched‚ in preparation for cell division. Part of the parent cells membrane surrounds the new daughter cells‚ as the newly generated organelles move inside the daughter cells and the chromosomes move into the newly developed nuclei and the cell

Mitochondria - Take in glucose via proteins that pass the plasma membrane and after it journey through the cytoskeleton to the mitochondria inside the cytoplasm. Endoplasmic Reticulum - Both ER types are covered in making essential cellular segments. For the most part in charge of the combination and handling of proteins that are either emitted from the cell or that end up stuck in the plasma film. The lipids made in the SER are joined with phosphorous to make phospholipids‚ the most inexhaustible
