Plant vs. Animal Cells
Name TWO structures found in both plant and animal cells.
nucleus, cell membrane, cytoplasm, mitochondria, ribosomes, or vacuoles.
A cell cannot control what enters and leaves. Which structure is not working correctly?
Cell membrane
Which planet is known as the Red Planet?
Mars
According to cell theory, what are all living things made of?
one or more cells
I'm invisible, but you need me to breathe. What gas am I?
Oxygen
A scientist finds a cell with a cell wall and chloroplasts. What type of cell is it most likely?
Plant Cell
Which organelle contains most of the cell's DNA and controls cell activities?
What is the largest organ in the human body?
Skin
Complete the principle: The cell is the basic unit of structure and ______ in living things.
Function
Which is heavier: a pound of brick or a pound of sock
Neither! They have the same weight
Which organelle allows plant cells to use sunlight to make food?
Chloroplast
A cell can make proteins but cannot properly sort and package them. Which organelle is malfunctioning?
Golgi Apparatus
What force keeps the planets orbiting the Sun?
Gravity
A new skin cell develops when an existing skin cell divides. Which principle of cell theory does this demonstrate?
All cells come from preexisting cells
A scientist discovers an organism made of only one cell. Can it still be alive?
Yes! Some organisms are unicellular and perform all life functions in one cell.
What is one major difference between vacuoles in typical plant and animal cells?
Plant cells usually have one large central vacuole; animal cells may have smaller vacuoles.
What is the difference between rough ER and smooth ER?
Rough ER has ribosomes and helps make and transport proteins. Smooth ER produces lipids.
An octopus has three hearts. How many hearts would five octopuses have altogether?
15 Hearts
A student says that an organism made of only one cell cannot be alive. Which principle helps prove the student wrong?
The cell is the basic unit of structure and function in living things.
I'm found inside the nucleus, and I help make the parts needed to build ribosomes. What am I?
Nucleolus
A student claims that only plant cells have vacuoles and only animal cells have mitochondria. Explain both mistakes.
Both cell types have mitochondria and can have vacuoles. Plants usually have one large central vacuole.
A cell must produce and send a protein outside the cell. Name THREE structures involved and explain what they do.
Ribosomes make proteins, rough ER helps process and transport them, and the Golgi apparatus modifies, sorts, and packages them.
An astronaut travels from Earth to the Moon. Does their mass change, their weight change, or both? Explain.
Their weight changes because the Moon has weaker gravity. Their mass stays the same.
Scientists discover a new living organism. Using cell theory, explain TWO things that must be true about this organism and its cells.
It must contain at least one cell, and its cells must come from preexisting cells. Also accept that cells are its basic units of structure and function.
A cell's nucleus is working, but its mitochondria stop functioning. What major problem will the cell experience?
It will struggle to produce enough usable energy to carry out its activities.
