Cahpter 10 Biology‚ 7e (Campbell) Chapter 10: Photosynthesis Chapter Questions 1) Organisms that can exist with light as an energy source and an inorganic form of carbon and other raw materials A) are called photoautotrophs. B) do not exist in nature. C) are called heterotrophs. D) are best classified as decomposers. E) both C and D Answer: A Topic: Overview Skill: Knowledge 2) Which type of organism obtains energy by metabolizing molecules produced by other organisms? A) autotrophs

to take place. These steps are light-independent reactions‚ and light dependent reactions. The occurrences of Light-independent reactions happen in the STROMA of the chloroplasts. The substances consumed during this reaction are ATP and NADPH. The occurrences of light-dependent reactions happen within the THYLAKOIDS of the chloroplasts. The substances consumed during this reaction is light‚ which is absorbed by chlorophyll molecules‚ which then produces hydrogen ions‚ electrons‚ oxygen gas‚ ATP and

We used transgenic tomato plants constitutively expressing HSP21 to study the role of the protein under stress conditions and during fruit

decreases. In our second experiment‚ we use three slices of aquatic plant Elodea and add pond water one leaf‚ distilled water for the second and 20% NaCl for the third‚ then observe the cells of each leaf with a compound microscope. Under microscope‚ chloroplasts (green organelles) in Elodea tend to bound to the cell wall in pond water‚ spread all over the cell in distilled water‚ pull away from cell wall in 20% NaCl. In our last experiment‚ we use a dialysis bag that contains 30% glucose and starch solution

oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration takes glucose and oxygen to make water and carbon dioxide. ● Chloroplasts have an outer and inner membrane. There is intermembrane space and thylakoid space. There is stroma and grana and thylakoid. Chloroplasts are found in mesophyll cells. ●The thylakoids is the part that most light energy is converted into chemical energy. Plants produce oxygen by photosynthesis and breaking the

H3C6H5O7‚ the H’s are separated. If you simplify the equation by adding up the H’s‚ then your answer will be C6H8O7. Light reactions take place on the thykaloid membranes of the chloroplast. Light reaction requires light and water‚ and produces ATP and Oxygen. Dark reactions take place in the stroma (fluid that fills the chloroplast. It uses the ATP produced in light reactions to make glucose. • What is the role of the electron transport system? Include the reactants and the

Biology‚ 7e (Campbell) Chapter 6: A Tour of the Cell Chapter Questions 1) All of the following are part of a prokaryotic cell except A) DNA. B) a cell wall. C) a plasma membrane. D) ribosomes. E) an endoplasmic reticulum. Answer: E Topic: Concept 6.2 Skill: Knowledge 2) The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. The most reasonable explanation for this observation is that A) plant cells are capable

1.A) Two main forms of cells exist: eukaryotic cells and prokaryotic cells. Prokaryotic cells are smaller and do not have membrane-bound nucleus or membrane- bound organelles‚ but do have: plasma membrane‚ cytosol and cytoplasm‚ and ribosomes. Prokaryotes contain much less DNA than eukaryotes and have circular chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins

After a few minutes the slide was observed for the movement of the chloroplasts. The movement of the chloroplasts was also recorded. A wet mount with a sample of an onion cell was prepared. The wet mount is prepared by placing a drop of water onto a glass slide. One thin layer of the onion was placed in the drop of water. One drop of
