Short answer
How does a scientist describe a Cell membrane as a Fluid Mosaic?
The fluid mosaic model states that the phospholipid bilayer behaves like a fluid more than it behaces like a solid
List three cellular functions that occur in the nucleus.
- The Nucleus is the site where DNA is transcribed into ribonucleic acid (RNA)
- RNA moves through nuclear pores to the cytoplasm
-Where, depending on the type of RNA, it carries our it function
What is the most functions of a eukaryotic cell are surrounded by with?
Nucleus
When a cell is not dividing, the DNA is in the form of a threadlike material called what?
Chromatin
Contrast three types of cytoskeletal fibers
1, Microtubulus- are hollow tubes made of a protein called tubulin
2, Microfilaments- are long threads of the beadlike actin and are linked end to end and wrapped around each other like two strands of a rope
3. Intermediate Filaments are rods that another anchor the nucleus and some other organelles to their places in the cell
What are the five major functions of a cell of the production in the protein?
Step 1- Protein are assembled by ribosomes on the rough ER
Step 2- Vesicles transport proteins to the Golgi apparatus
Step 3- The Golgi modifies proteins and packages them in new vesicles
Step 4- Vesicles release proteins that have da estination outside the cell
Step 5- Vesicles containing enzymes remain inside the cell as other types of Vesicles
Identify two characteristics that make mitochondria different from other organelles
-The outer membrane separates the mitochodrion from the cytosol
-The inner membrane has many folds, called cristae
What does the nucleus is filled with a jellylike liquid called?
Nucleoplasm
Is a network of thin tubes and filaments that crisscross the cytosol what it is called?
Cytoskeleton
