The diploid germ cells that have the potential to develop into ova are called oogonia. In humans, all of a female's oogonia that she will make in her lifetime are created when she's still a fetus and hasn't even been born yet.
How do hummingbirds reproduce? To attract hummingbirds to a garden or feeder, rich, bright colors should be used. Red is known to attract hummingbirds from afar but does not have to be the sole color used. Hummingbirds like both annuals and perennials, as long as the colors in the flowers are vibrant.
Once you have established your hummingbird garden, a great way to attract the birds to a specific location is to provide a hummingbird feeder. These are not traditional bird feeders but are designed to dispense a sugar-water solution.ummingbirds get nectar from plants, and plants get pollinated by hummingbirds. When the birds feed from flowers, they brush against them, and the pollen sticks to their heads and throats.
