Force & Motion
A push or pull on an object
What is Force
Has a definite shape and a definite volume
What is a solid.
What are Nucleus and Mitochondria
You observed a square shape cell under a microscope what organelles would you be able to observe ?
Cell Wall, Cell Memmbrane, Nucleus, Chloroplasts (if it’s a photosynthetic cell),Vacuole
What structures are present in an plant cell but not an animal cell?
Cell Wall, Chloroplasts and Large Central Vacuole
What unit is used to measure force?
What is Newton
The amount of space matter takes up
What is volume
What is the function of the nucleus?
Controls the cell’s activities and contains DNA
What is homeostasis?
Homeostais is the process by which living organisms maintain a stable internal environment despite changes outside.
What are tissues?
Give an example of tissue
Tissues are groups of similar cells that work together to perform a specific function.
Finish the statement...
An object in motion stays in motion, an object....
At rest stays at rest
What is a solid
Which organelle is correctly paired with its
specific function?
A. cell membrane-storage of hereditary information
B. chloroplast-transport of materials
C. ribosome-synthesis of proteins
D. vacuole-production of ATP
What is C : Ribosome – synthesis of proteins
Pick two organelles and describe how they work together to maintain homeostasis
Cell Membrane-Controls what substances enter and leave the cell.
Mitochondria - Produces energy (ATP) the cell needs to carry out functions, including the active transport of molecules.
Nucleus - Acts as the control center, sending out instructions to regulate cell activities.
What is the correct order of levels of organization for cells?
The correct order of levels of organization from smallest to largest is:
1. Cell → 2. Tissue → 3. Organ → 4. Organ system → 5. Organism
Define Acceleration
the rate at which an object's velocity changes over time
Why does ice float on water?
It is less dense than liquid water.
How do the nucleus and mitochondria work together?
The nucleus directs what needs to happen, and the mitochondria provide the energy to make it happen.
Mr.Hendricks and Ms. Worrell forgot to label the slides to put under the microscope. How are we able to tell the two cells apart under the microscope?
Shape and size, cell walls, arrangements of inside the cell, presence of organelles.
Damage to which structure will most directly
disrupt water balance within a single-celled
organism?
A. ribosome B. cell membrane
C. nucleus D. chloroplast
What is the cell membrane, the cell membrane controls what enters and leaves the body
What is Newton's first law of motion?
An object at rest stays at rest, an object in motion stays in motion.
Clouds form because water vapor undergoes this phase change
What is condensation.
Pick 3 organelles and describe how they work together to maintain homeostasis
Cell Membrane- Controls what enters and exits the cell.
Nucleus - Acts the control center, send instructions to the rest of the cells
Mitochondria- Produces the energy (ATP) needed for various cell processes.
What is the smallest unit of life?
What is a cell
Please list 5 organelles and their functions in the cell.
Nucleus-Controls cell activities and stores genetic material (DNA).
Mitochondria-Produces energy (ATP) through cellular respiration.
Ribosomes- Synthesizes proteins needed for various cell functions.
Cell Membrane- Regulates what enters and leaves the cell, maintaining homeostasis.
Chloroplasts (in plant cells)- Carry out photosynthesis, converting sunlight into chemical energy.
