Worksheet: • https://www.teacherspayteachers.com/P... • Flower reproduction is a process that requires male and female sex cells and some help from pollinators. The process of reproduction can be broken into two parts, pollination and fertilization. Pollination is the movement of pollen into the pistil. Pollen is the male reproductive cell and can be found on the stamen of flowers. Pollen must be moved from the stamen to the female part of the plant. The female part is called the pistil. The flower depends on pollinators to help with the movement. A bee is the most well-known pollinator. Bees are attracted to the bright colors of flowers. Bees are also attracted to the sweet nectar that the flowers produce. As the bee flies from flower to flower, grains of pollen get stuck to the bee. Sometimes a grain of pollen falls off of the bee and lands on the female reproductive part of the flower. Other pollinators are birds, wind, or water. Once the pollen lands on the pistil the plant has been pollinated. The next step in flower reproduction is fertilization. Fertilization is the joining of the male and female reproductive cells. When pollen lands on the pistil a pollen tube grows down a tube in the female part and meets with the egg. Genetic material from the pollen and egg combine. The development of a seed begins. If conditions are favorable a newly developed seed will grow into an adult plant. Flower reproduction can be summarized as pollination followed by fertilization.
