Hemp is the ONLY plant where the males appear one way and the females appear very different,?

Question

\\Hemp is the ONLY plant where the males appear one way and the females appear very different, physically! No one ever speaks of males and females in regard to the plant kingdom because plants do not show their sexes; except for hemp. To determine what sex a certain, normal, Earthly plant is: You have to look internally, at its DNA. A male blade of grass (physically) looks exactly like a female blade of grass. The hemp plant has an intense sexuality. //


Is this true ? it doesn't seem to be but I don't know?

Answer 1

No. There are other flowering plants where the male and female flowers differ in appearance. Many flowers have both male and female parts in the same bloom. And, no, you don't have to look at the DNA to determine male vs. female. The male parts produce pollen, the female produce ovules.

Answer 2

No, this happens in nature with other plants too. I take your question to mean that the structure of male flowers are different to those of its female flowers. Not all plants flower this way, most typically have male and female components in the same flower. Some have separate male and female plants.

One of the rubber plants Castilla Elastica has different male and female flowers, as an example.

I've tried to keep this on point, relating to the flowers only, not fruits etc, which are a follow-on product of flowers.

Good luck! Rob

Answer 3

No, it is not true. Many diverse plants exist as two separate sexes:- asparagus, kiwi fruit and holly to name but three totally different types of plant.
A male blade of grass may look like a female one, but a male hemp leaf looks like a female leaf from the same variety. (Grasses are however monoecious, it is dioecious plants, [separate sex], that we are concerned with here).
About 90% of plants have bisexual flowers and so do not show any difference between plants. The remaining 10% either have separate male and female flowers on the same plant, or are dioecious, (one sex per plant).

Answer 4

No, this is not the case.

Most of the plants of the world are asexual. They have both the male and female organs present on the same tree. There are many that have specific gender though. The Ginkgo biloba is one example of these. The female tree grows the fruit, and the male supplies the pollen. You never, ever want to have just a female Ginkgo tree. If the fruit isn't pollinated by a male, the fruit falls from the tree and smells like rotting meat! Nasty odor! Most Ginkgo trees sold are male for this specific reason.

Oh, and as far as apricots, they, like most fruits, have both male and female parts in the same flower. Some types of fruits need a pollinator (another tree of the same species but sometimes a different variety) for a couple of different reasons. 1. Genetic variety, kinda like why you shouldn't marry your sibling or cousin. 2. Many fruits are crossbred so their particular variety is not individually fertile, kinda like a mule.

Answer 5

No, it is not true. Many kinds of plants show their sexual difference by the flowers/seeds they produce. Bittersweet is one example I can think of. Female plants are the only ones that produce the beautiful orange berries; they can only do this, however, if there is a male plant to pollinate (fertilize) them. Certain fruit trees, such as (I think) apricots, also only produce fruit on a female tree if a male tree is present I am confident that there are many other examples; however, amatuer that I am, I can't be more specific.

Answer 6

I rather doubt that there is male and female grass.

Answer 7

I have no idea if it's true or not.

Answer 8

ok
