18 Questions
What is the main reason flowers produce an enormous amount of pollen compared to the number of ovules available for pollination?
To increase the chances of successful pollination due to uncertainties in pollen contact with stigmas
Which feature do wind-pollinated flowers typically possess to aid in the dispersal of pollen grains by wind?
Exposed stamens for easy pollen dispersal
Why do wind-pollinated flowers usually have a single ovule in each ovary?
To prevent wastage of pollen grains
What is a common characteristic of flowers undergoing water pollination?
Possession of feathery stigma
What aspect did the individual emphasize in his work related to the reproductive capacity of flowering plants?
Artificial culture of immature embryos
How long can some seeds remain alive after dispersal?
Thousands of years
Why is pollination by water rare in flowering plants compared to wind pollination?
Because most flowering plants lack adaptations for water pollination
What distinguishes pollination in lower plant groups, such as algae and bryophytes, from that in flowering plants?
Regular reliance on water for pollination in lower plant groups
Which of the following did the individual's work NOT involve in terms of reproductive capacity of flowering plants?
Asexual reproduction methods
How many eggs are typically present in an embryo sac of a flowering plant?
One
In what way did the individual contribute to school education, specifically biology textbooks?
By developing the first biology textbooks for Higher Secondary Schools

Which plant species had a 2000-year-old viable seed discovered near the Dead Sea?
Phoenix dactylifera
Why does the passage mention the beauty of flowers and their scents in relation to sexual reproduction?
To illustrate how flowers attract pollinators for sexual reproduction
Which plant had a viable seed excavated from Arctic Tundra that germinated after an estimated 10,000 years of dormancy?
Lupine arcticus
