Answers: is typically larger than a eukaryotic cell. does not have cytoplasm. does not have a membrane-bound nucleus. has no DNA. does not have ribosomes. Response Feedback: A prokaryotic cell does not have a membrane-bound nucleus. The DNA of prokaryotic cells is located in a region of the cytoplasm called the nucleoid region. Question 19 4 out of 4 points Which feature is found in all cells? Selected Answer: plasma membrane composed of phospholipids Answers: flagella cell wall composed of cellulose nucleus containing DNA nucleoid region that contains DNA plasma membrane composed of phospholipids Response Feedback : A plasma membrane made of phospholipids that regulates the movement of material into and out of the cell is one of the basic requirements for all cells. A nucleus containing DNA is only found in eukaryotic cells. The cell wall composed of cellulose is typically found only in plant cells. Flagella are not found on all cells. A nucleoid region is a feature unique to prokaryotes. Question 20 4 out of 4 points The O 2 given off during photosynthesis is derived from which compound? Selected
Answer: H 2 O Answers: H 2 O RuBP CO 2 NADP + CO 2 and H 2 O Response Feedback: The "leftover" from the splitting of water is ½O 2 , which combines to form O 2 . Question 21 4 out of 4 points The removal of electrons and/or hydrogen atoms from a substrate is called what? Selected Answer: oxidation Answers: an enzyme-substrate complex reduction oxidation metabolism phosphorylation Response Feedback: Oxidation is the loss of electrons or loss of hydrogen atoms. Question 22 4 out of 4 points The enzyme-rich solution found within the chloroplast is called the Selected Answer: stroma. Answers: cytoplasm. granum. chlorophyll. christae stroma.
Response Feedback: Among other things, the stroma contains enzymes that participate in the Calvin cycle reactions. Question 23 4 out of 4 points In a high latitude rainforest, the dominant type of photosynthesis is most likely to be Selected Answer: C 3 . Answers: C 4 . CAM. C 3 . both C 4 and CAM. both C 3 and CAM. Response Feedback: C 3 plants are generally more successful in environments with moderate temperatures and plentiful water. Under these conditions, it is not necessary to close stomata during the daytime to minimize water loss. Question 24 4 out of 4 points Carotenoids are found in high concentrations in yellow and orange leaves or vegetables. This color is seen because the carotenoid pigments Selected Answer: reflect and transmit yellow and orange wavelengths of light. Answers: absorb or reflect yellow and orange wavelengths of light. absorb or transmit yellow and orange wavelengths of light. reflect and transmit yellow and orange wavelengths of light. absorb yellow and orange wavelengths of light. absorb all wavelengths of light and then transmit yellow and orange wavelengths. Response Feedback: The colors that are seen from pigments are due to the reflection of transmission of those wavelengths of light. All others are absorbed. Question 25 4 out of 4 points
Which of the following organisms can perform photosynthesis? Selected Answer: algae Answers: algae invertebrates animals vertebrates fungi Response Feedback: Plants, cyanobacteria, algae, and some protists are capable of photosynthesis. Monday, October 14, 2019 12:55:49 PM EDT
