Photosynthesis
Name the 2 products of photosynthesis.
What are glucose (sugar) and oxygen (O2)?
Name the 2 reactants of cellular respiration .
What are oxygen (O2) and glucose (sugar).
Which type of cell has a cell wall: a plant cell, an animal cell, or both?
Plant cells.
During diffusion, do particles move from high to low concentration or low to high concentration?
High to low concentration.
What is the pH of a neutral solution?
7!
The organelle where photosynthesis takes place.
What is a chloroplast?
The mitochondria is the location of these 2 aerobic processes.
What are the Kreb's Cycle and Electron Transport Chain (ETC).
Which organelle makes proteins by joining amino acids together?
Ribosomes.
Does diffusion require the cell to use energy (ATP)?
No. Diffusion is a form of passive transport.
A student uses a 10× eyepiece and a 40× objective lens. What is the total magnification?
400× (10 × 40 = 400).
The main function of photosynthesis (main product).
The main function of cellular respiration (main product).
What is ATP (energy)?
What are the three main principles of cell theory?
All living things are made of cells; the cell is the basic unit of life; all cells come from pre-existing cells.
Which type of molecule moves during osmosis?
Water molecules.
Why do oil and water not mix easily?
Water is polar, while oil is nonpolar, so they do not attract each other sufficiently to mix.
The pigment found in green plants that absorbs sunlight.
What is chlorophyll?
Name of the 1st stage of cellular respiration for either aerobic or anaerobic respiration.
What is glycolysis.
Which organelle is responsible for releasing usable energy from food during cellular respiration?
Mitochondrion (mitochondria).
A cell is placed in a hypotonic solution. Which direction will water move overall?
Into the cell.
An acidic solution has a pH of 3. What must be added to neutralize the solution and bring its pH closer to 7?
A base, which reacts with the acid to neutralize it. The amount added must be appropriate to the amount of acid present.
The balanced equation of photosynthesis (number of each molecule needed).
6CO₂ + 6H₂O (+ light energy) → C₆H₁₂O₆ + 6O₂
The balanced equation of cellular respiration (number of each molecule needed).
C6H12O6 + 6O2 → 6CO2 + 6H2O [+ energy (32-36ATP)]
A plant wilts because its cells have lost water. Which organelle has lost volume, contributing to the loss of pressure that normally keeps the plant firm?
The central vacuole.
Oxygen moves from the blood, where its concentration is higher, into a body cell, where its concentration is lower. Is this diffusion or osmosis?
Diffusion!
Why are phospholipids able to form a bilayer in the cell membrane, with their heads facing the watery surroundings and their tails facing inward?
Their heads are polar and interact with water, while their nonpolar tails avoid water and face inward.
