Pollen Germination In Vitro — NEET Biology
📚 Practice ConceptYou can easily study pollen germination by dusting some pollen from flowers such as pea, chickpea, Crotalaria, balsam and Vinca on a glass slide containing a drop of sugar solution (about 10 per cent). After about 15-30 minutes, observe the slide under the low power lens of the microscope. You are likely to see pollen tubes coming out of the pollen grains.
Match the following structures from flowering plants with their correct characteristic or function: Column I (Structure) A. Tapetum B. Filiform apparatus C. Zygote D. Primary Endosperm Nucleus E. Micropyle Column II (Characteristic / Function) (I) Formed after syngamy (II) Nourishes developing microspores (III) Guides pollen tube into embryo sac (IV) Facilitates entry of O₂ and water into seed (V) Formed by triple fusion
