- Q1What are the products of photosynthesis?glucose and carbon dioxideglucose and oxygenwater and carbon dioxidewater and oxygen30s4.4.1.1
- Q2What are the three main limiting factors of photosynthesis?A, C, and EA, B, and EB, C, and EA, C, and D30s4.4.1.2
- Q3To make proteins, plants need to combine glucose with which other substance?Carbon dioxideOxygenNitratesStarch30s4.4.1.3
- Q4What is meant by a hydroponic system?Plants grown in water with a perfect balance of nutrientsPlants grown in air with the perfect balance of nutrientsPlants grown in a greenhousePlants grown in soil with the perfect balance of nutrients30s4.4.1.2
- Q5Where do plants get the nutrients required to make their cell walls?Plants get their nutrients from the Sun.Plants absorb the nutrients needed from the soil.Plants make their own nutrients from raw materials.Plants obtain nutrients by diffusion from the atmosphere.30s4.4.1.3
- Q6Which feature is an adaptation so that the cells inside the leaf get a good supply of carbon dioxide?Large air spaces in the leafBroad leaf with a large surface areaVeins containing xylemLots of chloroplasts in the palisade mesophyll30s4.2.3.1
- Q7The table shows different conditions that a plant was grown in. Which row shows the conditions that would result in the fastest rate of photosynthesis?ABCD30s4.4.1.2
- Q8During the day, what would be the correct movement of gases into and out of a leaf?Carbon dioxide and oxygen both out of the leafCarbon dioxide into the leaf and oxygen out of the leafOxygen into the leaf and carbon dioxide out of the leafCarbon dioxide and oxygen both into the leaf30s4.4.1.2
- Q9The graph shows the rate of photosynthesis over time. What is the factor limiting photosynthesis at point X?Light intensityConcentration of chlorophyll in the leavesTemperatureCarbon dioxide concentration30s4.4.1.2
- Q10What is NOT an advantage of farmers using a greenhouse to grow crops?Farmers can grow crops that would not normally grow in that area.Farmers can grow crops earlier in the year.Farmers can control the conditions inside a greenhouse.Farmers can increase the yield without increasing the cost of production.30s4.4.1.1
- Q11The graph shows the rate of photosynthesis and the rate of respiration in a plant as light intensity increases. Which statement is true at point X?The rate of photosynthesis is increasing but respiration has stopped.The production of carbon dioxide and oxygen will be equal.No carbon dioxide is being produced.The rate of photosynthesis and the rate of respiration are both increasing.30s4.4.1.2
- Q12A plant is growing in a dense forest early in the morning. What factor or factors would be limiting photosynthesis?Light intensity onlyTemperature and light intensityCarbon dioxide concentration and light intensityTemperature only30s4.4.1.2
- Q13Which statement about processes that occur in plants is false?Plants produce both carbon dioxide and oxygen.Iodine remains the same colour when exposed to a leaf that has been in the dark for 24 hours.Photosynthesis releases energy.Not all of the glucose produced in photosynthesis is used in respiration.30s4.4.1.3
- Q14Which is an economic advantage of a hydroponic system?Fewer staff are needed.Extra electricity is required to maintain light intensity.Computer software is required to control the conditions.A hydroponic system requires an enclosed area.30s4.4.1.2
