Lesson 4 Plant Reproduction Understanding Pollination Video

What is the primary definition of pollination?

• The movement of insects from one flower to another

• The growth of a pollen tube towards the ovule

• The transfer of pollen from the anther to the stigma

• The production of nectar by flowers

Which type of pollination involves flowers of the same plant?

• Cross-pollination

• Self-pollination

• Wind-pollination

• Insect-pollination

What feature do insect-pollinated flowers often have to attract insects?

• Feather-like stigmas

• Large quantities of pollen

• Brightly colored petals

• Exposed anthers

How do insects contribute to the pollination process?

• By eating the flowers

• By carrying pollen on their body from one flower to another

• By producing nectar

• By creating wind with their wings

What is a unique feature of wind-pollinated flowers?

• Sticky pollen grains

• Brightly colored petals

• Strong scent

• Feather-like stigmas

Why do wind-pollinated flowers produce large quantities of pollen?

• To feed birds and bats

• To attract more insects

• To ensure some pollen reaches another flower

• To look more appealing

What type of relationship exists between flowers and their pollinators?

• Parasitism

• Commensalism

• Mutualism

• Predation

Besides insects, which other animals are known to be pollinators?

• Birds and bats

• Fish

• Reptiles only
