General Cells & Microscopes
Fill in the blank:
All living things are made of ___________.
Cells!
What the main difference between prokaryotic and eukaryotic cells?
Eukaryotic cells have a nucleus, prokaryotic cells don't
What does the cell wall do? Do your cells have a cell wall?
Protects and supports the cell; No, animal cells don't have a cell wall
What is one kind of organism that can do photosynthesis?
*BONUS POINTS for listing one or two more types of organisms (up to 3)*
Plants, Protists, Bacteria
True or False: All plants & animals use cellular respiration.
True. All plants & animals need to get energy from their food.
What is the difference between a unicellular and multicellular organism?
Unicellular - made of only one cell
Multicellular - made of multiple cells
Give an example of both a prokaryote and a eukaryote.
Prokaryote - Bacteria
Eukaryote - Animals (Humans), Plants, Protists
What is the function of the nucleus? What important molecule does it contain?
Controls everything that goes on in the cell; contains DNA
Air/carbon dioxide (& water)
Why do we need to eat food?
To produce energy which is needed for literally almost everything our body does
Which of the following things are NOT living?
Bacteria, Rock, Seaweed, Dirt, Human, Grass, Rose, Cat
Rock & Dirt; they don't have cells
Which two organelles are found in plant cells, but not animal cells?
Cell wall and chloroplast
What is one organelle that will be found in ALL types of cell, and what is its function?
Cytoplasm - holds/suspends organelles of cell
Ribosomes - make proteins
Cell Membrane - allows materials to enter/leave the cell
What are the three things plants need to do photosynthesis?
Sunlight, air, & water
Read the following claim and explain whether it is correct or not:
"During cellular respiration, glucose is destroyed to create energy and carbon dioxide"
What is the technical term for the various "cell parts"?
Organelles!
Which organelle is found in animal cells, but not plant cells?
Lysosomes!
Photosynthesis - Chloroplast
Cellular Respiration - Mitochondria
Both plants and animals depend on photosynthesis for survival.
True because plants need photosynthesis to produce their food. Animals need plants to do photosynthesis so they can get food from the plants.
How is cellular respiration related to photosynthesis?
We need plants to do photosynthesis so we can get oxygen to breathe and glucose to eat (both needed for cellular respiration).
Describe how you might you use a microscope to tell if an unknown sample is living or non-living.
Look at the sample under a microscope to see if it has cells.
Describe how you might tell whether an unknown slide is a plant or animal cell using a microscope (include at least on organelle in your explanation).
Look at the cell under the microscope. If it has a cell wall or chloroplast, it is a plant cell. You can tell because the cell wall makes the cells look neater and more organized than animal cells which lack a cell wall.
Fill in the blank with an analogy AND explain your answer:
The cell membrane is just like a _____________.
Multiple possible answers:
Ex. The cell membrane is just like a door because they both allow things to enter and leave.
Write out the full equation for photosynthesis.
sunlight + carbon dioxide + water -> glucose + oxygen
Write out the basic equation for cellular respiration.
glucose + oxygen -> ATP + water + carbon dioxide
