Prepare for NEET Biology Plant Kingdom (Angiosperms) with MCQs & PYQs on NEET.GUIDE. Access free practice, previous year questions, and expert insights into flowering plants, double fertilization, and fruit formation.
The process in which one male gamete fuses with the egg cell and the other fuses with the polar nuclei is known as:
Double fertilization
Single fertilization
Triple fusion
Pollination
Which structure is formed as a result of the fusion of one male gamete with the polar nuclei during double fertilization?
Endosperm
Zygote
Embryo
Seed coat
The distinct vertical layering of plants based on their height is most evident in:
Tropical Rainforests
Grasslands
Deserts
Tundra
Which biome displays the most pronounced vertical stratification of plant life due to competition for light?
Tropical Rainforest
Temperate Deciduous Forest
Savanna
Taiga
Vertical stratification in a forest ecosystem primarily results from:
Competition for sunlight
Soil nutrient availability
Herbivore grazing patterns
Rainfall distribution
The emergent layer, canopy, understory, and forest floor are characteristic vertical layers of:
Tropical Rainforests
Grasslands
Tundra
Taiga
