Monday and Tuesday Daily Questions


 Daily Questions 
Monday October 22nd
I look under a microscope and see rigid cell walls and green structures inside cells.  Because of this what can I infer about the cell?
 That it is most likely a plant cell.  Just the presence of a cell wall does not automatically make it a plant cell because bacteria also have cell walls.  The presence of the chloroplast does that indicate that it is a plant cell.

Some disorders are caused by a lack of lysosomes in the cells of a particular tissue, what would result from this? (what would happen in the cell?)
 Since lysosomes aid in breaking down cellular "junk" and removing it from the cell the lack of those would cause a build up of wastes and the cell would become "toxic"

If the golgi apparatus was out of order in a cell, what would the direct result of that be regarding protein production and transportation?

Since the golgi apparatus is responsible for putting finishing touches on proteins that were made in the rough endoplasmic reticulum, it these were out of order protein that were meant to be shipped out of the cell would not.

A Scientist observed a protein that had been processed in the endoplasmic reticulum of a cell and then entered the cytoplasm.  Where will the protein most likely go next?
       A. It will move to a ribosomes that will release it outside the cell
     B.   It will move to a ribosomes to be packaged in a vesicle for transport
     C.   It will move to a golgi apparatus that will then release it outside the cell
       D.  It will move to a golgi apparatus to be packaged in a vesicle for transport
Which statement BEST describes the role that is common to chloroplasts and mitochondria in plant cells?
     A.The both use light to produce energy
      B They both are involved in protein synthesis
     C.They both convert organic compounds into ATP
     D. They both are involved in energy transformations
Which structure and function are common to both prokaryotes and eukaryotes?
     A.Mitochondria that generate usable energy for the cell
     B.Mitochondria that control what enters and exits the cell
     C. A cell membrane that generates usable energy for a cell
    D. A cell membrane that controls what enters and exits a cell
Ribosomal subunits made of protein and Ribosomal RNA are assembled within the nucleus.  To which organelle will these ribosomal subunits MOST LIKELY be transported?
    A.Vacuole      B.  Mitochondria      C.  Golgi apparatus       D.  Endoplasmic Reticulum
Which feature is common to all prokaryotic and eukaryotic organisms?
a. Endoplasmic reticulum that stores fat reserves
b. Ribosomes that produce complex carbohydrates
c. Nucleic acids that code for genetic characteristics
d. Mitochondria that are sites for cellular respiration.
