Which two plants require buzz pollination?

Buzz pollination is a specialized process that occurs when certain plants release their pollen through vibrations created by pollinators, particularly bumblebees. This method is essential for the successful fertilization of some plants, making them dependent on this form of pollination to produce fruit or seeds.

Tomatoes and blueberries both require buzz pollination as part of their reproductive cycle. Bumblebees are particularly effective at this because they can vibrate their bodies rapidly while gripping onto the flower, causing the pollen to dislodge and fall onto the bee or onto other parts of the flower for fertilization. This technique increases the efficiency of pollen transfer, leading to better fruit set and quality in these crops.

Other options, such as sunflowers and corn, do not require buzz pollination; instead, they rely on wind or non-vibrational pollination methods. Similarly, roses and orchids have different pollination strategies that do not involve the buzzing technique, nor do apples and grapes depend on it to fertilize. Understanding the specifics of how different plants are pollinated is crucial for effective gardening and agriculture, especially when considering the role of specific pollinators.
