Plant parts
What does xylem carry up the stem?
What does phloem carry up the stem?
Water and Nutrients,
Sugar
Which are the anaerobic processes found in your lecture?
Glycolosis, lactic acid fermentation, alcoholic fermentation
What are the products of photosynthesis?
oxygen and glucose
The interior space of the chloroplast is called:
Stroma
How are cellular respiration and photosynthesis related, in terms of energy?
The energy captured in photosynthesis is used to power cellular respiration.
Plants gather the sun's energy with light-absorbing molecules. The principal one being _____
Chlorophyl
__________ releases energy slower than ________.
Cellular respiration, fermentation
What does the following equation represent:
6CO2 + 6H2O --> 6O2 + C6H12O6
Photosynthesis
Where do the light-dependent reactions occur?
Where does the light-independent reaction occur?
thylakoid membrane
Stroma
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?
Only species Y is anaerobic
The innermost floral parts that shelter the female gametophytes and seeds is called _____.
Carpels
Explain the brief steps from glucose to citric acid.
Glucose breaks into two pyruvic acid molecules then gets added to the 4carbon chain in the kreb cycle.
The cycle that keeps the amounts of carbon dioxide and oxygen fairly constant in the atmosphere
A cycle made by photosynthesis and cellular respiration
Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?
The light-independent stage (The Calvin Cycle)
What are the electron carrier molecules in cellular respiration?
NADH and FADH2
The male part of the flower that consists of _____ with an ____ at its tip is called what?
filament, anther, stamens
Name the three stages of cellular respiration and where they occur in the cell.
Glycolosis- cytoplasm
Kreb cycle- mitochondria matrix
Electron transport cells- mitochondrial membrane
In humans during strenuous physical activity, due to a low amount of oxygen, the body uses which form of respiration?
Aerobic and anaerobic.
The electrons for the Light Reactions come from
Water
If a plant died from lack of food, which structure is most likely missing or damaged?
leaves
Terrestrial plants have stomata on the surface of their leaves. A single stomata is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. What best explains how the structure of the leaf is used in processes that occur in plants?
Gases for photosynthesis are exchanged through the surface of the leaf.
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
As the cells run out of oxygen they switch to anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.
Is ADP or ATP more like a fully charged battery, and why?
ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
What is the first stop in photosynthesis process? Where does this process occur
Photosystem 2, the thylakoid membrane
Two test tubes were filled with a solution of bromthymol blue. A student exhaled through a straw into each tube, and the bromthymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. What best explains why the solution in the tube placed in sunlight returned to a blue color?
Oxygen was produced by photosynthesis.
