Male pine cones have a sticky fluid, sperm tubes, and pollen sacs.
Explanation:
Both male and female pine cones have sperm tubes, but only females have soft scales. Male cones have rough scales that let the pollen in and out of it. Although female cones soft scales, they still allow pollen to enter into the cones. The pollen that goes into the female pine cone never gets out, though.
Male cones are a lot smaller than female cones and their scales aren't as open. Each scale in a male cone contains the pollen that can spread to a female cone to make a seed.
Explanation:
I don't know what you are asking but that is my answer.....be more specific.
If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak. ... The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
