1 B2 Quick Revision Questions
2 Question 1 Which raw materials are used in photosynthesis and what are the products of the reaction?
3 Answer 1 Carbon dioxide Water Glucose Oxygen
4 Question 2 What type of reaction is photosynthesis?
5 Answer 2 Endothermic
6 Question 3 What is the word and symbol equation for photosynthesis?
7 Answer 3 Carbon dioxide + Water Glucose + Oxygen
8 Question 4 What is the symbol equation for photosynthesis?
9 Answer 4 6H CO 2 C 6 H
10 Question 5 A leaf was tested for starch. The iodine stayed orange What does this tell you about the leaf? What conditions was it kept in?
11 Answer 5 There was no starch present Left in the dark so no photosynthesis
12 Question 6 Why are light and chlorophyll needed for photosynthesis?
13 Answer 6 Light need for energy Chlorophyll this is where photosynthesis takes place
14 Question 7 How does the shape of a leaf help photosynthesis to happen?
15 Answer 7 Large surface area for light to absorbed Thin so a short distance for the carbon dioxide to diffuse
16 Question 8 What is the function of vascular bundles?
17 Answer 8 To transport water to the leaf and glucose away from the leaf.
18 Question 9 Describe the function of the mesophyll cell?
19 Answer 9 Palisade mesophyll carries out photosynthesis Spongy mesophyll has air spaces to allow for the diffusion of gasses
20 Question 10 Suggest why stomata are found on the lower epidermal tissue?
21 Answer 11 The stomata are on the underside because it lowers the rate of transpiration. (less heat to evaporate water from the leaf)
22 Question 12 How will increases the light intensity affect the rate of photosynthesis?
23 Answer 12 Increasing the photosynthesis increases the rate of photosynthesis
24 Question 13 How would you describe environmental conditions in tropical forest, tundra and desert ecosystems?
25 Answer 13 Tropical forest dense plant life Tundra few plant species grow Desert few plant species grow
26 Question 14 Suggest an advantage of a tree having needles rather than flat broad leaves
27 Answer 14 Reduces surface area for water loss
28 Question 15 Why do many greenhouses have vents in the roof?
29 Answer 15 Helps to remove oxygen and replace with carbon dioxide
30 Question 16 Explain why paraffin heaters are used in greenhouses?
31 Answer 16 They produce carbon dioxide and they increase the temperature on colder days and nights
32 Question 17 How do greenhouses increase yield?
33 Answer 17 This is intensive farming. It optimises conditions for photosynthesis. Protects plants from weather and damage from being eaten by animals
34 Question 18 What are the five ways plants use glucose?
35 Answer 18 Proteins for plant growth and repair Used as energy To make cellulose for cell walls Stored as starch Stored as fats and oils
36 Question 19 Why is glucose stored as starch?
37 Answer 19 Starch is insoluble, stored for when it is needed by the plant.
38 Question 20 What is the relationship between photosynthesis and respiration in leaves?
39 Answer 20 Plants use carbon dioxide to photosynthesise and produce oxygen. They use some of the oxygen for respiration and produce carbon dioxide.
40 Question 21 What was John Baptist van Helmont s theory on plant growth?
41 Answer 21 He thought that the increase in mass of a willow tree was due to water, not just because of minerals in the soil.
42 Question 22 What is diffusion?
43 Answer 22 The net movement of particles from an area of high concentration to lower concentration due to a random movement of particles, until equilibrium is reached.
44 Question 23 How could you increase the rate of diffusion in living systems?
45 Answer 23 Increasing the surface area. Decrease the distance the particles have to travel. Increasing the concentration gradient.
46 Question 24 What external factors can affect the rate of diffusion from leaves?
47 Answer 24 Wind increases the concentration gradient High humidity decreases the concentration
48 Question 25 How does external temperature affect the rate of diffusion?
49 Answer 25 As the temperature increases the molecules gain kinetic energy and move faster, so the rate of diffusion will increase.
50 Question 26 What is transpiration?
51 Answer 26 The movement of water of water through a plant.
52 Question 27 What is the path of water through a plant?
53 Answer 27 Water enters through the root hairs. Water passes into the roots and travels up the stem in xylem vessels to the leaves. Water escapes through the stomata.
54 Question 28 What conditions increase the rate of transpiration?
55 Answer 28 Temperature. Light availability. Wind. Humidity.
56 Question 29 Why is transpiration important to plants?
57 Answer 29 Evaporation of water cools leaves. Water is used in the process of photosynthesis. Cells full of water become turgid and support the plant. Water carries dissolved materials around the plant. E.g. nitrates, potassium, phosphates.
58 Question 30 What is the test for starch?
59 Answer 30 Test with iodine, if starch is present leaf goes blue/black
60 Question 31 What is bicarbonate indicator used for? What is the colour change?
61 Answer 31 It indicates an acid eg carbonic acid. The colour change is red to yellow/orange
62 Question 32 What did Priestly find?
63 Answer 32 That plants give off oxygen in the light
64 Question 33 What is a limiting factor?
65 Answer 33 A factor that limits the rate of photosynthesis e.g. light, carbon dioxide, temperature.
66 Question 34 What is hydroponics?
67 Answer 34 Growing plants without soil in a controlled environment.
68 Question 35 What colour light is best for photosynthesis?
69 Answer 35 Red and blue
70 Question 36 List the adaptations of a leaf to prevent water loss?
71 Answer 36 Reduce the leaves to spines e.g. cactus Curl leaves Stomata in pits Hairs Waxy cuticle
72 Question 37 What is translocation?
73 Answer 37 Movement of sugars and amino acids in phloem.
74 Question 38 What is the structure of a xylem Vessel?
75 Answer 38 Dead hollow tube, reinforced with lignin to give a continuous column of water.
76 Question 39 What is the structure of Phloem vessel?
77 Answer 39 It is made from living sieve tubes and companion cells These move sucrose and amino acids in both directions
78 Question 40 Describe how surface area:volume affects water loss in plants. Give an example of a plant with a small surface area:volume
79 Answer 40 The larger the surface area the greater the water loss An example is a cactus.
