Module 2 Keytask 3 Biology Flashcards
What is the function of a flagellum in a cell?
Helps the cell to move
What does chromosomal DNA provide to a bacterial cell?
Extra advantageous DNA, e.g. for antibiotic resistance
What is the role of mitochondria in cells?
Where respiration takes place to release energy
What is the equation for aerobic respiration?
GLUCOSE + OXYGEN → CARBON DIOXIDE + WATER
What is the function of vacuoles in plant cells?
Holds cell sap, gives the cell shape
What is the role of ribosomes in a cell?
Where proteins are made
What does the cell membrane control?
Controls what enters and exits the cell
What is photosynthesis?
The process by which plants convert light energy into chemical energy
What is the balanced equation for photosynthesis?
6CO₂ + 6H₂O + LIGHT → C₆H₁₂O₆ + 6O₂
What are stomata?
Small openings on the leaf surface that allow gas exchange
Fill in the blank: Photosynthesis occurs in the _______ of plant cells.
chloroplasts
True or False: Animals perform photosynthesis.
False
What are the four main types of white blood cell defenses against pathogens?
- Phagocytosis
- Antibody production
- Antitoxin release
- Memory cell formation
What is the role of phagocytes?
Engulf and digest pathogens
What do vaccinations do?
Prepare the immune system to respond quickly to pathogens
What do plants use glucose for? List at least three uses.
- Respiration
- Making cellulose
- Storing as starch
- Producing proteins
What is the process of respiration?
The breakdown of glucose to release energy
What is the primary gas that plants take in during photosynthesis?
Carbon dioxide
What is the difference between the air we breathe in and the air we breathe out?
We use oxygen in respiration and produce carbon dioxide
Fill in the blank: The energy for photosynthesis is provided by _______.
light
What is the function of the xylem in plants?
Transport water and nutrients from roots to leaves
What is the role of chlorophyll in photosynthesis?
Absorbs light energy to drive the process
