Cells and Viruses both contain—
Genetic Material.
Viruses can only reproduce within a—
Host Cell.
Viruses can ___________ in the air through ___________________________________.
Spread, Coughing and sneezing.
Do Viruses or Cells contain Genetic Material?
Both.
Do Viruses or Cells require a host cell to replicate?
Viruses.
Do Viruses or Cells have structures that include a lipid envelope, capsid, and projection?
Viruses.
Do Viruses or Cells have membrane-bound organelles?
Cells.
A group of students in a high school Biology class is reviewing information about the Influenza Virus. What statement correctly describes how Influenza spreads and reproduces?
The flu virus uses the cell’s machinery to replicate and produce new virus particles, which then spread through coughing, droplets, and direct contact.
Emma is looking at two different types of cells under a microscope. The first cell is very simple with genetic material floating in the cytoplasm. The second cell is larger, has a clearly defined nuclear membrane. What statement best describes the two cells Emma is observing?
The first cell is prokaryotic, and the second cell is eukaryotic.
Where is the nucleic acid located in prokaryotic and eukaryotic cells?
Pro: Cytoplasm
Euk: Nucleus
Are there membrane-bound organelles in prokaryotic and eukaryotic cells?
Pro: No
Euk: Yes
Are the cells in prokaryotic and eukaryotic cells simple or complex?
Pro: Simple
Euk: Complex
Are there ribosomes in prokaryotic and eukaryotic cells?
Pro: Yes
Euk: Yes
The _______________________ controls what can enter and exit the cell.
Cell Membrane.
Complex _____________________________ are used for energy.
Carbohydrates.
The __________________ transports large molecules across the plasma membrane.
Channel Proteins.
Rough ER belongs to?
Protein.
Nucleus belongs to?
Nucleic Acid.
Smooth ER belongs to?
Lipid.
Chloroplast synthesizes glucose belongs to?
Carb.
Codes for traits belongs to?
Nucleic Acid.
Enzymes in lysosome breakdown waste belongs to?
Protein.
Imagine a cell is preparing to produce a large amount of lipids for membrane formation and energy storage. Which organelle is primarily involved in this process, and what is its main function in lipid production?
Mitochondrion— it generates energy required for lipid synthesis.
Statements related to enzymes.
- Are specific to the substrate they bind to
- Use less energy to synthesize a product
- Protein
- Speed up how fast reactions occur (catalyst)
- Can be denatured by extreme temperatures or pH, work best at optimal conditions
What is the Photosynthesis equation?
Radiant energy —-> Photosynthesis —-> Chemical Energy (Glucose) —-> Cellular Resp —-> Chemical Energy (ATP)
Stores chemical energy as glucose?
Photosynthesis.
Enzymes aid in breaking down the reactants to create products?
Both Photosynthesis and Cellular Respiration.
Radiant Energy to Chemical Energy?
Photosynthesis.
Removes Oxygen from the atmosphere?
Cellular Respiration.
Uses reactants to synthesize products?
Both Photosynthesis and Cellular Respiration.
Stores chemical energy as ATP?
Cellular Respiration.
Imagine a large sunflower growing in a field, absorbing sunlight and performing photosynthesis to produce glucose. A rabbit comes along and eats some of the sunflower’s leaves. What statement correctly describes the flow of energy from the sunflower to the rabbit through photosynthesis and cellular respiration?
The sunflower converts sunlight into chemical energy, which is stored in glucose. The rabbit consumes the leaves, breaking down the glucose during cellular respiration to release energy for movement.
In diffusion, molecules move from an area of __________ concentration to an area of _________ concentration.
High, low.
All forms of ________________________ move _________________ with the ___________________________________________, no energy required.
Passive Transport, molecules, concentration gradient.
When a ________ is placed in a ___________________________________, water will ____________ the cell causing it to ___________.
Cell, Hypertonic Solution, leave, shrink.
__________________ and passive transport are ______________ to maintain ________________________.
Active, needed, homeostasis.
