How do flowering plants depend on animals How do animals depend on flowers?
Animals help plant reproduction by helping spread plant pollen and seeds. For example, bees pollinate flowers, which is vital to spreading genes and reproducing.
How do hummingbirds know which flowers have nectar?
Scientists believe hummingbirds are attracted to red flowers because they’ve learned through experience that red tubular flowers contain the most nectar. So anything red—be it a flower, baseball hat or tricycle—triggers their instincts to investigate. That’s why hummingbird feeders usually have red feeding ports.
Which plants are pollinated by hummingbirds?
Brightly-colored flowers that are tubular hold the most nectar, and are particularly attractive to hummingbirds. These include perennials such as bee balms, columbines, daylilies, and lupines; biennials such as foxgloves and hollyhocks; and many annuals, including cleomes, impatiens, and petunias.
What kind of relationship exists between the hummingbirds and the flowering plants?
Hummingbirds and plants represent a classic example of a plant-pollinator relationship. Some 7000 species of plants now depend for pollination on one or more of the 361 known species of hummingbird.
What is the description of bees pollinate flower?
When a bee collects nectar and pollen from the flower of a plant, some pollen from the stamens—the male reproductive organ of the flower—sticks to the hairs of her body. When she visits the next flower, some of this pollen is rubbed off onto the stigma, or tip of the pistil—the female reproductive organ of the flower.
Why does the bee sit on flower?
Honey bees and some other insects are often seen sitting on flowers. This is because they are collecting the sugary fluid secreted within flowers. This fluid is called nectar. The pollen grains get carried by bees to the female reproductive part (carpel) which helps in reproduction of plants.
What plants are aphids most attracted to?
Aphids are especially attracted to mustard and nasturtium. Plant these near more valuable plants as traps for the aphids. (Check your trap plants regularly to keep aphid populations from jumping to your valued plants.) Nasturtiums spoil the taste of fruit tree sap for aphids and will help keep aphids off of broccoli.
