The 20 questions

  1. Which part of a flowering plant produces pollen grains?

    • Stigma
    • Ovary
    • Sepal
    • Anther

  2. What is the transfer of pollen from anther to stigma called?

    • Pollination
    • Fertilisation
    • Dispersal
    • Germination

  3. After fertilisation, which part of the flower develops into the fruit?

    • The ovary
    • The anther
    • The sepal
    • The petal

  4. In a flowering plant, where does fertilisation take place?

    • Stigma
    • Anther
    • Ovule
    • Petal

  5. Which feature is typical of a wind-pollinated flower?

    • Bright petals
    • Feathery stigmas
    • Sweet nectar
    • Heavy pollen

  6. Which feature is typical of an insect-pollinated flower?

    • Bright petals
    • Feathery stigmas
    • Light pollen
    • Dull bracts

  7. A plant has dull flowers, no scent, and light pollen. What is its pollination method?

    • Bird pollination
    • Insect pollination
    • Self pollination
    • Wind pollination

  8. Which example shows plant seed dispersal by wind?

    • Eaten berry
    • Burr on fur
    • Dandelion parachute
    • Floating coconut

  9. Which example shows plant seed dispersal by animals?

    • Exploding pod
    • Eaten fruit
    • Water float
    • Wind parachute

  10. What causes explosive seed dispersal in some dry pods?

    • Insect burrowing
    • Sudden splitting
    • Animal chewing
    • Rainfall weight

  11. Which seed structure helps seeds stick to animal fur?

    • Feathery hairs
    • Sticky wings
    • Small hooks
    • Waterproof husk

  12. Why can a coconut travel across the sea to new islands?

    • Wind parachute
    • Waterproof husk
    • Explosive pods
    • Animal hooks

  13. In an experiment dropping seeds from different heights, what is the independent variable?

    • Drop height
    • Seed mass
    • Landing distance
    • Air temperature

  14. Why do many wind-dispersed seeds have wings or parachutes?

    • Attract insects
    • Slow their fall
    • Absorb water
    • Deter predators

  15. Why must fertilisation happen before a seed can develop?

    • Hardens the fruit
    • Attracts pollinators
    • Fuses genetic material
    • Produces petal colour

  16. Which part of the flower receives pollen?

    • The stigma
    • The anther
    • The filament
    • The sepal

  17. Which part of the female part of a flower contains the ovules?

    • The ovary
    • The filament
    • The stigma
    • The style

  18. After fertilisation, what do the ovules develop into?

    • Seeds
    • Fruits
    • Pollen grains
    • Petals

  19. A fruit is produced with no seeds inside. What is the most likely reason?

    • Too much water
    • No fertilisation
    • High soil pH
    • Strong sunlight

  20. Which part of a flower protects the developing bud?

    • The filament
    • The stigma
    • The ovary
    • The sepal
