- Figure 5.7 On a hot, dry day, plants close their stomata to conserve Water. What impact will this have on photosynthesis?arrow_forwardWhich of the following occurs during the carbon-fixation reactions of photosynthesis? A. Water is converted into hydrogen and water. B. CO2 is converted into sugars. C. Chlorophyll acts as an enzyme. D. Nothing occurs; the plant rests in the dark. E. Glucose and oxygen are reduced to CO2 and water.arrow_forwardIf plants need CO2 to construct glucose (by photosynthesis), why is the rising level of CO2 in the atmosphere cause for concern? You’d think more CO2 would accelerate plant growth, and that would be a good thing.arrow_forward

(Don’t say light and dark cycle)arrow_forwardPhotosynthesis occurs in the _______________ of the cell. The first part occurs in the _____________ and the second part occurs in the _______________.arrow_forwardThe figure below shows the concentration of glucose for a 24-hour period on both the process of photosynthesis (blue) and cellular respiration (red dashed lines). What explains the increase of respiration rate during the day? a. Enzymes are active during the day. b. Glucose production has increased due to photosynthesis. c. More energy is required to transport water and phloem sap and to dissipate heat. d. All of the above.arrow_forward
- Plants do have to consume nutrients for other purposes, but most plants don’t have to eat for energy because they can... Group of answer choices a)catch animals and eat them. b)pull up nutrients from the soil. c)make glucose through photosynthesis. d)produce oxygen through photosynthesis. e)take up carbon dioxide from the air.arrow_forwardIn a rainforest there are a wide variety of plants. Short plants have broad, flat leaves . Tall plants have small, narrow leaves. What is an advantage of short plants having broad , flat leaves ? to transport nutrients through the plant to prevent water loss from transpiration to obtain energy by breaking bonds in glucose to capture energy used for photosynthesisarrow_forwardConsider the relationship between temperature and photosynthesis. As temperatures increase,gases such as CO2 diffuse faster. As a result, plant leaves will lose CO2 at a faster rate thannormal. If the amount of light reaching the leaf and the amount of water available are adequate,predict how this loss of gas will affect photosynthesis in the leaf.arrow_forward
- What is the major trade-off plants face when they undergo photosynthesis? When they open their stomata to let in oxygen, they can lose water. When they open their stomata to release oxygen, they can lose water. When they open their stomata to let in carbon dioxide, they can lose water. When they open their stomata to let in water, they can lose carbon dioxide.arrow_forwardThe basic raw materials for photosynthesis are: sugar and carbon dioxide. water and carbon dioxide. oxygen and water. sugar and water. oxygen and carbon dioxidearrow_forwardCells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The photosynthetic reaction releases free energy to the surroundings. The photosynthetic reaction’s free energy is in equilibrium. The reactants of photosynthesis have less free energy than the products. The change in free energy (∆G) of the photosynthetic system is less than zero.arrow_forward
