Nature of Science
Name a piece of lab equipment that you could use to measure mass.
Scale, electronic balances, triple beam balance
What is biology?
Biology is the study of living things.
Which is the "Powerhouse" of the cell
Mitochondria
What is the difference in shapes between an animal cell and a plant cell?
Plant cells are rectangular due to the cell wall, while animal cells have a cell membrane that makes them irregular shape.
What is the first step of the scientific method?
Observe the world and ask a question (one that is testable)
Name a difference between animal and plant cells
cell wall, chloroplast, vacuole, shape
What is a unicellular organism? Name an example.
Organisms with only one cell; bacteria
Which cell has lysosomes and what is their function?
Animal cells have lysosomes and they are the clean up crew that break down waste materials, bacteria, and old cell parts, as well as recycling necessary materials.
What is a hypothesis?
A hypothesis is an educated guess based on background research
What is the function of the Phloem?
To transport sugars throughout the plant
In plant cells, this organelle stores water, nutrients and food:
Vacuole
In both of these cells, which organelle is known as the "powerhouse"?
Mitochondria
In this scenario, identify the independent variable and dependent variable.
I am testing different kinds of surfaces on the same incline with my new wind up toy car to figure out which surface allows it to travel farther.
Independent variable: different inclined surfaces (i.e., smooth, bumpy, stairs)
Dependent variable: how far the wind up toy will travel
What are two main seed plant groups called, and what is the difference between them?
Gymnosperms and Angiosperms
Gymnosperms have seeds in cones, while angiosperms have seeds in fruits/flowers
What is the function of the Golgi Apparatus?
It packages and ships proteins throughout the cell.
Name at least 10 organelles found in animal cells.
Cell membrane, nucleus, vacuole, ribosomes, mitochondria, smooth ER, rough ER, lysosomes, cytoplasm, golgi body, centrosome
Convert the following:
1. 25 g to mg
2. 12 L to daL
3. 49 km to m
1. 25,000 mg
2. 1.2 daL

Name all five levels of organization: from largest to smallest
Organism, Organ System, Organ, Tissue, Cell
What are the organelles that only animal cells have? What are their functions.
Lysosomes and Centrosomes.
Lysosomes: help with getting rid of waste
Centrosomes: help with cell division
Name at least 10 organelles found in plant cells.
