4.4.2 Pollination

• What is the definition of pollination?

  Transfer of pollen
• Pollination is the transfer of pollen from the anther of a stamen to the stigma of a pistil.stigma
• There are three primary types of pollination: self-pollination, cross-pollination, and wind pollination.

  False
• Where does the pollen source come from in self-pollination?

  Same plant
• What type of genetic variation results from cross-pollination?

  High
• Plants undergoing cross-pollination are not dependent on pollinators.

  False
• Wind pollination, also known as anemophily, relies on wind currents to transfer pollen.pollen
• What type of petals do wind-pollinated plants have?

  Small petals
• Wind pollination ensures efficient use of pollen.

  False
• Match the pollination type with its feature:

  Wind pollination ↔️ No fragrance

  Insect pollination ↔️ Large petals
• What is the term for water pollination?

  Hydrophily
• Plants adapted for water pollination have light pollen to float on water.water
• Water-pollinated plants typically have reduced or absent petals.
• What carries pollen in water pollination?

  Water
• Water-pollinated plants do not produce fragrance to attract pollinators.fragrance
• Match the pollination type with its characteristic:

  Hydrophily ↔️ Light pollen

  Anemophily ↔️ Feathery stigmas

  Entomophily ↔️ Sticky stigmas
• What is a pro of water pollination in aquatic environments?

  No reliance on pollinators
• A con of water pollination is its inefficient pollen transfer.transfer
• Wind-pollinated plants produce fragrance to attract pollinators.

  False
• What is an advantage of wind pollination over insect pollination?

  Wide dispersal range
• Match the pollination type with its feature:

  Wind pollination ↔️ High pollen production

  Insect pollination ↔️ Sticky stigmas
• What is the primary adaptation of water-pollinated plants for pollen dispersal?

  Light pollen
• Water-pollinated plants have specialized stigmas to capture floating pollen.stigmas
• What is another name for water pollination?

  Hydrophily
• In hydrophily, pollen is transferred from the anther
• In hydrophily, insects are the primary pollen carriers.

  False
• Match the pollination method with its pollen production level:

  Hydrophily ↔️ High

  Anemophily ↔️ Very High

  Entomophily ↔️ Low
• What is the petal size of hydrophily plants?

  Small
• Hydrophily plants lack fragrance
• The stigma type in hydrophily is specialized.
• List the adaptations of insect-pollinated plants:

  1️⃣ Large petals

  2️⃣ Sweet fragrance

  3️⃣ Nectar for energy

  4️⃣ Sticky pollen
• What is the pollen carrier in insect pollination?

  Insects
• Bird-pollinated plants produce fragrance to attract birds.

  False
• Pollination is the transfer of pollen from the anther to the stigma
• What are the two primary types of pollination?

  Self and cross
• Pollination is the transfer of pollen from the anther to the stigma, enabling fertilization in plants.pistil
• There are two primary types of pollination: self-pollination and cross-pollination.
• Match the pollination type with its key feature:

  Self-pollination ↔️ Pollen from the same plant

  Cross-pollination ↔️ Pollen from a different plant
• Self-pollination occurs when pollen is transferred from the anther to the stigma on the same plant.
• Cross-pollination involves the transfer of pollen between two different plants.
