- Q1What is the purpose of photosynthesis?To break down glucoseTo make glucoseTo release energyTo make carbon dioxide30s
- Q2What are the reactants (molecules needed for the reaction) in photosynthesis?Water and oxygenLight and carbon dioxideWater and glucoseCarbon dioxide and water30s
- Q3Why is light needed for photosynthesis?It provides the energy neededIt adds the mass to make sugarSo the plant can see what it's doingIt helps to keep the plant green30s
- Q4
The process of photosynthesis takes in energy from the surroundings (in the form of light energy).
Is this type of reaction endothermic or exothermic?
EndothermicExothermic30s - Q5Which tissues carry out photosynthesis?Mesophyll tissueUpper epidermal tissueVascular tissueWaxy cuticle30s
- Q6What is a 'tissue'?A group of organisms working together to perform a functionA group of organs working together to perform a functionA group of cells working together to perform a functionA group of organelles working together to perform a function30s
- Q7What is the purpose of chlorophyllTo release carbon dioxideTo absorb light energyTo carry out respirationTo make the plant green30s
- Q8What is the by-product of photosynthesis?GlucoseOxygenCarbon dioxideWater30s
- Q9Which organelles are responsible for photosynthesis?MitochondriaChloroplastsVacuolesRibosomes30s
- Q10What type of molecule is glucose?ProteinCarbohydrateFatStarch30s
- Q11What is the name of the organelle shown in the picture?RibosomeChloroplastMitochondriaNucleus30s
- Q12Which of these is NOT one of the ways that plants use glucose (made during photosynthesis)To make starchTo make cellulose cell wallsTo make amino acids (together with nitrates)Muscle contraction30s
- Q13How do plants get the water needed for photosynthesisTaken into the phloem by active transportTaken into root hair cells by osmosisAbsorbed by the leaves following rainMade from carbon dioxide30s
- Q14Which of the following is NOT needed for photosynthesis?WaterCarbon dioxideLightOxygen30s
- Q15Which of the following is the correct word equation for photosynthesisGlucose + water ---> carbon dioxide + oxygenGlucose + oxygen ---> carbon dioxide + waterCarbon dioxide + glucose ---> water + oxygenCarbon dioxide + water ---> glucose + oxygen30s
