List the 4 features that ALL cells have
White blood cells protect the body against invaders. What organelle do you think plays a critical role in doing their job?
Lysosome
Define "organelle"
tiny organ
Unicellular organisms are made up of 1/more than 1 cell...
1
Cell wall of bacteria is made of
peptidoglycan
Distinguish between cilia and flagella
Cilia: short, numerous, move fluid across the membrane
Flagella: long, 1-3, move a cell
List two differences between smooth & rough ER
1) ribosomes, 2) make proteins / lipids
Which of the following are eukaryotes?: fungi, animals, bacteria, protists, plants
1. all living things are made of cells
2. cell is basic unit of life
3. cells come from preexisting cells
Tails of phospholipid are: (hydrophilic/hydrophobic)
hydrophobic
What are the 2 main types of cells?
Eukaryotic and prokaryotic
What is the role of the golgi apparatus?
Package, sort, distribute proteins
Fat cells store energy/lots of lipids in one particular organelle...which one?
Vacuole
What is the role of a vesicle?
short term transport of substances
Heads of phospholipid are: (hydrophilic/hydrophobic)
hydrophilic
Draw the nucleus and label the following parts: nuclear membrane, nucleolus, chromatin
:)
Where does cellular respiration take place?
Mitochondria
The phospholipid bilayer can be described with this model:
Cell wall of plants is made of
cellulose
True/false: a cell wall surrounds every cell
false
Muscle cells require a lot of energy to produce movement. Which organelle do you think they have a lot of?
Mitochondria
Which macromolecule is considered the "information molecule," and where is it stored in eukaryotic cells?
DNA; nucleus
What 2 things make up a ribosome?
rRNA + protein
Organelle involved with cell division/moving chromosomes
centriole (2 together = centrosome)
Name one difference between plant and animal cells
1) plants have a wall, 2) plants have a large central vacuole, 3) animal cells have centrioles & lysosomes
