- Q1Name the chemical reaction that leaves are adapted to carry outRespirationAbsorptionPhotosynthesisCombustion30s
- Q2Complete the following equation for photosynthesis: Water + Carbon dioxide-> ___________ + OxygenFoodEnergyGlucoseLight30s
- Q3Name the part of the plant labelled.StomataWaxy cuticleCellCarbon dioxide30s
- Q4What are is the arrow pointing to inside the palisade cell?ChloroplastsStomataSpongy layerLeaf30s
- Q5What does the black circle in the cell represent?Cell wallVacuoleChloroplastsNucleus30s
- Q6What does the this part of the leaf represent?Palisade cellHoleStomataXylem30s
- Q7What gas diffuses into the leaf through the stomata?WaterCarbon dioxideOxygenNitrogen30s
- Q8What controls the size of the stomataChloroplastsGuard cellsMuscle fibresStomata contractors30s
- Q9Why are leaves covered in a waxy cuticle?To carry out photosynthesisTo reflect lightTo make it look prettyPrevent water loss, diseases entering, and weather damage30s
- Q10What is the function of the xylem?Transport water to the leaf from the rootto transport blood around the plantTransport food away from the leafTransport water from the leaf to root30s
- Q11Why would the leaf need to guard cells to control the size of the stomata?To stop insects getting inTo keep the leaf warm.To stop oxygen getting inTo minimise water loss on hot days30s
- Q12Which of these is an adaptation of a palisade cell?Surrounded by a waxy cuticleContains lots of chloroplastsContains a nucleusContains no nucleus30s
- Q13Name the cells at the edge of the gapsGuard cellsPalisade cellsStomataNucleus30s
- Q14Name the part of leaf indicated by the red arrowStomataWaxy cuticlePalisade cellSpongy layer30s
- Q15Why are gaps in the spongy layer an important adaptation of the leaf?So water can easily be transported to the cellsto prevent water lossSo there is space for cellsSo carbon dioxide can easily reach the palisade cells and oxygen can easily leave30s
