What am I?
Location of protein synthesis
Ribosome
HL What features are shared by all viruses?
small, fixed size, nucleic acid as genetic material, capsid, no cytoplasm, few/no enzymes
State the role of iodine in making slides
Stain - to make specimen visible
Identify the organelle indicated with the arrow.
Mitochondria
How many nm are in a μm?
1000nm
What organelles exist in plant cells but not animal cells?
Cell Wall
Large central Vacuole
Chloroplasts
What does a lysosome do?
Break down substances using enzymes
Identify the organelles shown in the micrograph.
Rough Endoplasmic Reticulum
Smooth Endoplasmic Reticulum
Name the 7 functions of life
homeostasis, metabolism, nutrition, movement, excretion, growth, response to stimuli, reproduction
HL Which virus cycle does NOT kill the host during reproduction
Lysogenic cycle
Draw a chloroplast
Must be an oval with discs inside representing grana
HL What is the purpose of the folds in a mitochondria?
To increase surface area
Draw and label a diagram of a prokaryotic cell.
See slides
70S ribosomes, DNA present, same size, double membrane
Name the protein that aids in vesicle formation
Clathrin
State two adaptations to increase surface area (HL)
Flattening, invagination (folding)
Ribosomes on it make proteins, Rough ER packages them to leave the cell
Identify the organelle shown in the micrograph.
Golgi apparatus/Golgi body
State the three points of cell theory
Living organisms are composed of one of more cells
A single cell is the smallest unit that can carry out all the functions of life
All cells are formed from preexisting cells.
HL Name of the experiment recreating initial conditions of Earth
Miller-Urey experiment
HL State how one type of cell uses flattening to adapt to its function
Type I pneumocytes - more SA for gas exchange, less distance
Red blood cells - no nucleus, more space for oxygen to bind
Outline the function of the cytoskeleton
Structural support, cell movements (with microtubules and microfilaments)
Identify the type of cell shown in the micrograph.
Plant cell
Draw and label a diagram of a plant cell
Must include: nucleus, mitochondria, chloroplasts, sap vacuole, ribosomes, Golgi apparatus, rough and smooth endoplasmic reticulum, and DNA
