• Self-pollination only happens at night
• Cross-pollination involves two different species of plants
• Self-pollination involves the same plant, while cross-pollination involves separate plants of the same species
• Cross-pollination only occurs with insects

Why do insect-pollinated flowers produce sticky or spiky pollen grains?

• To prevent insects from eating them
• To help them stick to insect bodies during transport
• To make them taste better to insects
• To protect them from rain

How do wind-pollinated flowers differ from insect-pollinated flowers?

• They have larger, more colorful petals
• They produce more nectar
• They have exposed anthers and feather-like stigmas
• They have a stronger scent

What type of ecological relationship exists between insects and flowering plants during pollination?

• Parasitism
• Competition
• Mutualism
• Predation

Why do wind-pollinated flowers produce more pollen than insect-pollinated flowers?

• To make the flowers look prettier
• Because much of the pollen will be lost in the wind
• To attract more insects
• To protect against rain damage

Which feature would NOT be typically found in a wind-pollinated flower?

• Bright colored petals
• Feathery stigmas
• Light pollen grains
• Exposed anthers

Why are nectaries located below the anthers in insect-pollinated flowers?

• To keep the nectar cool
• To force insects to brush against the anthers while reaching for nectar
• To protect the nectar from rain
• To make it easier for insects to find

Besides insects, which of these is NOT mentioned as a pollinator in the video?

• Birds

What makes stigmas effective in insect-pollinated flowers?
