BIO100 Final Exam || with errorless answers.
what is cell theory? correct answers 1. all organisms are made up of one or more cells
2. cells are the basic unit of life and the smallest unit of life
3. every new cell comes from a pre-existing cell
what is the plasma membrane? correct answers maintains the cell as a distinct entity
cytoplasm correct answers consists of semi-fluid material and organells
organelles correct answers tiny compartments within a cell that have specific functions
DNA correct answers hereditary information found within a distinct nucleus in eukaryotes
-found floating around in prokaryotes
RNA correct answers stores information like DNA and catalyzes reactions (like proteins)
functions of the plasma membrane? correct answers 1. separates internal and external
environment
2. controls movement of materials in and out of cell
3. allows cell to interact with other cells
what is the structure of the plasma membrane? correct answers 1. phospholipid bilyaer with
hydrophilic heads on the outside and hydrophobic tails on the inside
2. proteins and other lipids are embedded within the membrane
what are ribosomes composed of? what are their function? correct answers composed of RNA
and protein molecules
, -assemble amino acids into proteins
what kind of forms of life are prokaryotic? what are some main features of prokaryotic cells?
correct answers 1. bacteria and archaea
2. have no distinct nucleus (DNA is found in cytoplasm)
3. contain few organelles other than ribosomes
4. they have a cell wall
what are some of the main structures and organelles of eurkaryotic cells? correct answers 1.
nucleus
2. endomembrane system
3. mitochondria
4. chloroplasts
5. cytoskeleton
what is the endomembrane system? what organelles make it up? correct answers 1. they are the
organelles involved in the synthesis, storage, and transportation of important molecules
(conveyor belt of the factory)
2. endoplasmic reticulum, golgi complex, various vesicles
whats the difference between the rough ER and the smooth ER? correct answers the rough ER
has ribosomes and is where protein synthesis occurs
-the smooth ER has no ribosomes and is the site of lipid synthesis and transport
what is the golgi complex do? correct answers 1. receives macromolecules from the ER
2. assemble, modify, and package macromolecules for exporting from the cell
what are vesicles? correct answers involved in transport, storage, and recycling
