What are the fundamental units of life? - correct answer ✔-All organisms are
made of cells
-The cell is the simplest collection of matter that can live (that has the
properties of life)
-Cell structure is correlated to cellular function
-All cells are related by their descent from earlier cells
Why is learning about cell structure and function important? - correct answer
✔-To understand more advanced concepts in biology, you need to be familiar
with cells and parts of the cell (e.g. organelles- "little organs") and what they
do
What is the range in size of most cells? - correct answer ✔1-100 um
(microns)
What is the size range of prokaryotic cells? - correct answer ✔0.1-5.0 um
(microns)
What is the size range of eukaryotic cells? - correct answer ✔10-100 um
(microns)
Name three types of microscopes that can be used to study cells? - correct
answer ✔Transmission electrons microscopy, bright field light microscopy,
and scanning electron microscopy
Cell size-
,Bacteria size-
Plant and animal cells- - correct answer ✔1-100 um
0.1-10 um
10-100 um
How do biologists study the parts that make up a cell?
What's cell fractionation? - correct answer ✔-Cell biology/biochemistry
-Cell fractionation is used to study subcellular components of cells; uses
centrifuge at different speeds ( and therefore different force) to separate
different sized parts of cells
Prokaryotic cells slide:
Pro=_________
Kary=kernel/ ___________
-____________________ separates cell interior from exterior only allowing in
or out certain substances
-____________________ outside plasma membrane; provides protection
-____________________ contents in inferior of cell
-____________________ build proteins - correct answer ✔Before
Nucleus
-Plasma membrane
-Capsule
-Cytoplasm
-Ribosomes
, ***DNA located in area of cell called nucleoid (no membrane surrounding)
Eukaryotic cells slide:
Eu=_________
Kary=kernel/ __________
-Unlike prokaryotic cells, eukaryotic cells contain ___________ "small
organs".
-_______________ all of the interior of cell except the nucleus
-_______________ contents of the cell, excepting nucleus and organelles -
correct answer ✔Cytoplasm
Cytosol
Eukaryotic cells-plants vs. animal slide:
Kingdoms are:
1.)
2.)
3.)
4.)
Cell structure: Animal cells plant cells
Nucleus
Cell wall
