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.
Flowers lure pollinators in several ways, with color as their main attractant. Bees are drawn to yellow, blue and white but cannot see red. When you spot a bee burrowing deeply into a red or pink flower, the center of the flower is probably yellow. The center holds the flowerâs reproductive organs.
