BIO100 Final Exam Questions and
Answers 100% Solved
what is cell theory? - CORRECT ANSWER-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 ANSWER-maintains the cell as a
distinct entity
cytoplasm - CORRECT ANSWER-consists of semi-fluid material and organells
organelles - CORRECT ANSWER-tiny compartments within a cell that have
specific functions
DNA - CORRECT ANSWER-hereditary information found within a distinct
nucleus in eukaryotes
-found floating around in prokaryotes
RNA - CORRECT ANSWER-stores information like DNA and catalyzes
reactions (like proteins)
,functions of the plasma membrane? - CORRECT ANSWER-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 ANSWER-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
ANSWER-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 ANSWER-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

, 2. endomembrane system
3. mitochondria
4. chloroplasts
5. cytoskeleton
what is the endomembrane system? what organelles make it up? - CORRECT
ANSWER-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
ANSWER-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 ANSWER-1. receives macromolecules
from the ER
2. assemble, modify, and package macromolecules for exporting from the cell
what are vesicles? - CORRECT ANSWER-involved in transport, storage, and
recycling
what are lysosomes? - CORRECT ANSWER-the vesicles fro animals
-house enzymes that digest macromolecules (like carbs and proteins)
what are central vacuole? - CORRECT ANSWER-the vesicles from plants
