Exam No:0610_s23_qp_13 Year:2023 Question No:27
Answer:
D
Knowledge points:
16.3.1 Identify and draw, using a hand lens if necessary, the sepals, petals, stamens, filaments and anthers, carpels, style, stigma, ovary and ovules, of an insect-pollinated flower
16.3.10 Investigate and state the environmental conditions that affect germination of seeds, limited to the requirement for water, oxygen and a suitable temperature
16.3.11 Define self-pollination as the transfer of pollen grains from the anther of a flower to the stigma of the same flower or different flower on the same plant
16.3.12 Define cross-pollination as transfer of pollen grains from the anther of a flower to the stigma of a flower on a different plant of the same species
16.3.13 Discuss the implications to a species of self-pollination and cross-pollination in terms of variation, capacity to respond to changes in the environment and reliance on pollinators
16.3.14 Describe the growth of the pollen tube and its entry into the ovule followed by fertilisation (details of production of endosperm and development are not required)
16.3.2 State the functions of the sepals, petals, anthers, stigmas and ovaries
16.3.3 Use a hand lens to identify and describe the anthers and stigmas of a wind-pollinated flower
16.3.4 Distinguish between the pollen grains of insect-pollinated and wind-pollinated flowers
16.3.5 Define pollination as the transfer of pollen grains from the anther to the stigma
16.3.6 Define pollination as the transfer of pollen grains from the anther to the stigma
16.3.7 Define pollination as the transfer of pollen grains from the anther to the stigma
16.3.8 State that fertilisation occurs when a pollen nucleus fuses with a nucleus in an ovule
16.3.9 Describe the structural adaptations of insect-pollinated and wind-pollinated flowers
