Q1. The fire alarm went off at a school so the students lined up to exit the building.
Which is the stimulus?
Which is the response?
Stimulus - fire alarm ringing
Response - lining up to exit the school
Q6. What are the three parts of the cell theory?
All organisms are made up of one or more cells
The cell is the smallest unit of life
Cells come from pre-existing cells
I’m thick and like jelly. I fill up every cell. I protect all that’s inside, including organelles.
What am I?
_____cytoplasm__________________
I’m a semi-permeable membrane, just like a cell’s skin. I decide what goes out as well as what comes in.
What am I?
____cell membrane___________________
What three organelles do plant cells have that are different from animal cells?
1. chloroplasts
2. Cell walls
3. Large vacuoles
Q2. List the characteristics of living things.
1. Made of cells
2. Take in and use energy
3. Sense and respond to changes in the environment
4. Share similar chemicals
5. reproduce
6. Grow and develop
Both Prokaryotic & Eukaryotic
Found in both plants and animals
(Bacteria)
Function: Determines what goes into and out of the cell
Cell Membrane
I am the powerhouse of the cell, and I make energy. I break down food to release ATP.
What am I?
____mitochondria____________
I’m made by the nucleolus, creating proteins as building blocks. I can be free or on ER,
I’m an organelle that rocks!
What am I?
___ribosome____________________
Prokaryotic & Eukaryotic
Found in Plants
(Bacteria)
Function is: Support and structure
Cell Wall
Q3. What are the four needs of living things and why is each important?
1. Food - for energy
2. Shelter - a habitat that provides a place to live (sleep, eat, find water, find mates)
3. Water - necessary for all life functions
4. Homeostasis - maintaining stable internal conditions
Eukaryotic
Found in both plants and animals
Converts food into ATP energy
Mitochondria
I am rigid and stiff, and I keep a cell strong. I’m found only in plants, I’ve been there all along.
What am I?
___cell wall____________________
I’m like a water tower, fluid filled, collecting waste. I hold materials for the cell so nothing gets displaced.
What am I?
____vacuole___________________
Eukaryotic
Found in both plant and animals
Function: Processes, packages and transports proteins and lipids throughout the cell. Creates vesicles for material transport
Golgi Bodies
Q4. List in order the levels of organization and provide an example of each.
LEVEL EXAMPLE
1. Cell red blood cell
2. Tissue cardiac muscle
3. Organ heart
4. Organ system circulatory system
5. Organism frog
Both Eukaryotic & Prokaryotic
Found in both plants and animals
(Bacteria)
Makes proteins which are building blocks of cells and their organelles
Ribosome
I’m the boss of the cell telling others what to do. I control the cell’s activities, which in turn is controlling YOU.
What am I?
_____nucleus__________________
I make glucose, a sugar, and I’m found in plants like trees. I’m green and I’m sly, using the sun’s energy.
What am I?
______chloroplast_________________
Eukaryotic
Found in both plants and animals
Function: Removes waste from the cell
Lysosome
Q5. Who is Robert Hooke and why did he choose the name “cell” to describe what he saw in the slice of cork?
Robert Hooke was the father of microscopy who looked at a piece of cork and coined the term “cell” because the tiny boxes he saw in the cork reminded him of a monk’s living quarters in a monastery which are called cells.
Eukaryotic
Found in plants and animals
Stores water, enzymes, waste
Vacuole
I transport materials throughout the whole cell. I’m like a train or UPS, moving proteins and other things as well.
What am I?
_____endoplasmic reticulum__________________
The structures that are located inside the cell are called
____organelles___________________
Both Eukaryotic & Prokaryotic
Found in both plants and animals
(Bacteria)
Function: Provides shape for cell and protects organelles
Cytoplasm
