Random
A plant growing towards the light is an example of which characteristics of life?
The reactants in photosynthesis.
Carbon dioxide, water, and light energy.
What are the products of photosynthesis?
These organelles contain digestive enzymes to break down waste.
Lysosomes.
This is why water molecules are attracted and stick to other surfaces or materials (like the inside of a glass tube).
Adhesion.
tiny, complex molecular machines found inside all living cells. Their primary function is to act as biological protein factories.
Ribosome
In which organelle does photosynthesis occur?
Chloroplast
The process that breaks down food and creates energy in the presence of oxygen.
Aerobic
This principle of cell theory states that all cells come from existing cells.
Cell Theory
Polar or charged substances that readily interact with and dissolve in water are known as this, meaning "water-loving."
Hydrophilic.
What is a byproduct of pickling fermentation that bacteria produce?
Carbon dioxide or lactic acid.
Gases enter and exit through which structure in leaves?
Stomata
The jelly-like fluid inside the cell where the very first steps of cellular respiration take place.
Cytoplasm
This broad type of cell contains a true nucleus and membrane-bound organelles.
Eukaryotic cells.
Because oxygen has a higher electronegativity than hydrogen, the oxygen side of the molecule has a slight negative charge, while the hydrogen side has a slight positive charge.
Polarity
How many ATP does glycolysis produce?
2 ATP
Which colors are least absorbed in photosynthesis?
Green and yellow.
Yeast undergoes this type of fermentation, producing alcohol and carbon dioxide as byproducts.
Alcoholic fermantation
Animal cells use these paired cylindrical structures during cell division.
Centrioles.
This polysaccharide stores energy in human liver and muscle cells.
Gylcogen.
What is the optimal pH range for most enzymes in humans?
6-8 (Any answer in the range is ok.)
What are the organelles inside the chloroplast called that capture sunlight?
Thylakoid
Why do bread doughs rise when yeast undergoes fermentation?
Because of the release of carbon dioxide gas.
The process by which a cell engulfs large particles by folding its membrane inward.
Endosymbiosis
Iodine turns dark purple or black in the presence of this specific polysaccharide.
Starch.
