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.
Many plants pollinated by hummingbirds produce flowers in shades of red, orange, and bright pink, though the birds will take nectar from flowers of many colors. Hummingbirds can see wavelengths into the near-ultraviolet, but their flowers do not reflect these wavelengths as many insect-pollinated flowers do.ummingbirds do not spend all day flying, as the energy cost would be prohibitive; the majority of their activity consists simply of sitting or perching. Hummingbirds eat many small meals and consume around half their weight in pure sugar (twice their weight in nectar, if the nectar is 25% sugar) each day.
