what are the differences between the reproductive apparatus of flowering plants and mammals?

Answer 1

All said there really isn't very much difference in the organs themselves. The male organs in flowering plants are pistils. They produce and deliver the male zygote (pollen). The stamen is the female organ. It is sticky and has a tube leading to the female zygote (egg). The pollen is delivered, by various means (insects and spiders can transfer it, birds, wind) to the stamen, goes down the tube, fertilizes the egg.

Both organs are present in the same flower and there are, of course, many flowers.

The fertilized egg develops into the seed which, eventually, finds its way into soil (or some other growth medium), is nourished and develops into a plant.

I will assume that you understand what the reproductive organs of mammals and processes involved are.

The pistol is very similar in both form and function to the testes and penis. The stamen is similar to the vagina, vulva, uterus, and ovaries. It's external rather than internal. The pistols and stamen are far less complex systems but still quite similar.

Thus the big, obvious differences are, most simply: External female organ, redundancy of reproductive organs (lots of flowers), simultaneous existence of both organs, fully functioning, in the same body, reliance on an outside entity for cross fertilization, and live birth vs. seeds (seeds being more analogous to species of animals that use eggs to develop the fetus).

For more detailed and in depth comparison I'd suggest some sort of biology text book.

Answer 2

i used to work at a nursery and one of the girls i worked with went to school for horticulture and one thing she taught me was. a weed is defined as unwanted. So i there is something that is technically a weed " like by the books " but a gardener likes it then to them its not really a weed. Take for instance crabgrass is a weed but so are those purple flowery things ( cant remember their name ) that sprout up all over the grass. They are both weeds "by the books" but some people choose to keep the purple stuff but would defiantly get rid of that crabgrass. Good Luck

Answer 3

Flowers spread there seeds and animals spread there seed usually depending on the plant eg. bee's spread pollin in flowers, mammals have sexual intercourse
