|
What is Mitosis?
|
Exact duplication of a cell, retains all genetic information [Clonining]
|
|
|
What is Miosis?
|
Reproduction by combination of genetic information [I.E. sperm delivering part of genetic information to an egg in mammalian reproduction]
|
|
|
What is the Nucleus and its functions?
|
Organelle surrounding the Nucleolus, contains the DNA for the cell and manages movement of ribosomes from nucleolus to the rough ER
|
|
|
What is the Nucleolus?
|
Found within the Nucleus, maintains and repairs genetic information, and handles the assembly of DNA and ribosomes
|
|
|
What are Ribosomes?
|
Product of the Nucleus, responsible for protein synthesis on the Endoplasmic Reticulum
|
|
|
What are Nuclear Pores for?
|
Controls movement of material across the nuclear membrane into and out of the Nucleoplasm and the Cytoplasm
|
|
|
What is the Golgi Apparatus for?
|
Organelle responsible for condensing and packaging protein packages for extra-cellular movement. Hormones are an example product of the Gogli Apparatus
|
|
|
What is the Rough Endosplasmic Reticulum for?
|
Handles intra-cellular ribosome movement and allows ribosomes to attach to it to initiate protein production.
|
|
|
What is the Smooth Endosplasmic Reticulum?
|
Takes in material and converts it to products useful to the cell. In animals this product is typically Glycogen. Some are specialized [in the Liver S.ER are for de-tox]
|
|
|
What are Lysosomes for?
|
Containing Enzymes needed for breaking down old cell material and foreign matter for new materials and energy.
|
|
|
What is the main function of the Mitochondria?
|
Production of ATP from chemical energy via the process of Metabolism.
Typically this is in the form of Glucose. [break down bonds to release energy] |
|
|
What are Chloroplasts?
|
Plant cell organelles that produce energy from light energy. This is accomplished by the Chlorophyll contained in Thykaloids.
|
|
|
Mossman Specific Hint: What does the presence of Thykaloids indicate?
|
That the organelle is a Chloroplast, and that the cell is a plant cell!
|
|
|
What is the most efficient way for quickly moving extra-cellular protein packages?
|
Attach a tag in the Golgi-Apparatus.
|
|
|
Ribosomes are assembled where?
|
Nucleus or Nucleolus are acceptable answers.
[Choose nucleus ONLY if this is the only one listed, else nucleolus to be safe] |
|
|
What is the difference between a Peroxisome and a Vacuole?
|
Peroxisomes are special purpose Vacuole to contain toxic peroxides. Vacuoles store material such as water and starch.
|
|
|
What is the Cytoskeleton?
|
Sub cellular structure for organizing organelles within cytoplasm
|
|
|
What is the difference between flagelle and cillia?
|
Flagella are motor organneles for moving the cell. Cillia are responsible for moving extra-cellular material.
|
|
|
What are stem cells?
|
Self renewing and capable of forming any cell in the organism. Stem cells able to form any cell are called Totipotent
|
