  • What is the process of pollination in plants?
    Transfer of pollen
  • Pollination involves the transfer of pollen from the anther to the stigma, enabling fertilization.
  • Steps involved in self-pollination
    1️⃣ Pollen is released from the anther
    2️⃣ Pollen is transferred to the stigma of the same plant
  • Steps involved in cross-pollination
    1️⃣ Pollen is released from the anther
    2️⃣ Pollen is transferred to the stigma of a different plant
  • Self-pollination results in high genetic variation in plants.
    False
  • What is a major advantage of wind pollination for plants?
    No reliance on pollinators
  • Plants adapted for wind pollination have small petals and no fragrance
  • Wind pollination is highly efficient in transferring pollen.
    False
  • Adaptations for water pollination
    1️⃣ Light pollen to float on water
    2️⃣ Reduced or absent petals
    3️⃣ Specialized stigmas
  • What is water pollination also known as?
    Hydrophily
  • Plants adapted for water pollination have light pollen to float on water
  • Match the pollen carrier with the type of pollination:
    Water ↔️ Hydrophily
    Wind ↔️ Anemophily
    Insects ↔️ Entomophily
  • Water pollination is highly efficient in transferring pollen.
    False
  • What is a major advantage of water pollination for plants?
    Works in aquatic environments
  • What is the term for water pollination?
    Hydrophily
  • Water pollination involves the transfer of pollen from the anther to the stigma by water.
  • Plants adapted for hydrophily have light pollen to float on water.
  • What is the term for insect pollination?
    Entomophily
  • Insect pollination relies on insects to transfer pollen from the anther to the stigma.
  • Large petals are an adaptation for insect-pollinated plants.
  • What is the term for bird pollination?
    Ornithophily
  • Bird-pollinated plants have brightly colored petals to attract birds.
  • Bird-pollinated plants produce sweet fragrance to attract pollinators.
    False
  • Define pollination.
    Transfer of pollen
  • Pollination involves the transfer of pollen from the anther to the stigma.
  • Match the type of pollination with its characteristic:
    Self-Pollination ↔️ Pollen transfer within the same flower
    Cross-Pollination ↔️ Pollen transfer between different flowers
  • Self-pollination involves the transfer of pollen within the same flower.
  • What is the primary drawback of cross-pollination?
    Reliance on external agents
  • What is pollination in plants?
    Transfer of pollen
  • There are two primary types of pollination: self-pollination and cross-pollination
  • Match the pollination type with its pollen source:
    Self-Pollination ↔️ Same plant
    Cross-Pollination ↔️ Different plant
  • Where does pollen transfer occur in self-pollination?
    Same plant
  • Cross-pollination results in high genetic variation.
  • Wind pollination is also known as anemophily
  • What is a major disadvantage of wind pollination?
    Inefficient pollen use
  • Plants adapted for water pollination have light pollen to float on water.
  • Match the pollination method with its primary feature:
    Hydrophily ↔️ Light pollen
    Anemophily ↔️ Feathery stigmas
    Entomophily ↔️ Sweet fragrance
  • What type of stigma do insect-pollinated flowers have?
    Sticky
  • Insect pollination is also called entomophily
  • Insect-pollinated flowers produce nectar to attract pollinators.
