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.
While there are a variety of styles for hummingbird feeders, most have one thing in common â a blazing red color. Like a neon sign blinking âVacancyâ at the side of a highway, the color red captures the hummingbirdsâ interest and beckons them over to feast.
