Basic Cell Structures Flashcards
Do humans consist of prokaryote or eukaryote cells?
Eukaryote cells
What are the similar components between prokaryote and eukaryote cells?
Plasma membrane, cytosol, DNA, RNA, proteins and ribosomes
What are the differences between eukaryote cells and prokaryote cells?
Eukaryote cells have membrane bound organelles and are much larger
Does the nucleus of a prokaryote cell have a membrane?
No
What is included in the cytoplasm?
Everything inside the plasma membrane excluding the nucleus
Are organelles included in the cytoplasm?
Yes
What is the fluid portion of the cytoplasm called?
Cytosol
What does the cytosol consist of?
Water and suspended dissolved substances (ions, ATP, proteins, lipids, etc.)
Which major organelles are within the endomembrane system?
The Nucleus, Endoplasmic reticulum (smooth and rough), Golgi apparatus and Lysosomes
Which major organelles are not part of the endomembrane system?
Mitochondria and ribosomes
The plasma membrane is a selectively ___ barrier
Permeable
The plasma membrane is a ___ layer of ___ with associated ___
A double layer of phospholipids with associated proteins
The tail of a phospholipid is made of a ___ and is hydro___
Made of a lipid (fatty acid) and is hydrophobic
The head of a phospholipid is made of a ___ and is hydro___
Made of a phosphate and is hydrophillic
Are the plasma membrane and the proteins associated with it static?
No, they are dynamic depending on the role of the cell at a given time
