How many petals,sepals,stamen,pistils are there in the Hibiscus, Gulmohar, Petunia n in Jasmine flowers?

Hibiscus-5petals


When petals and sepals are hard to distinguish between, what is a good method ?

(I realize that sometimes they are called tepals because they apparently can't be distinguished apart.) (Someone once said it had to do with where on the hypanthium/receptacle they originated...?)

When petals and sepals are hard to distinguish between, what is a good method ?
The sepals will be the ones closest to the stem, at the very bottom of the flower.


Is there any significance of a flower that has a certain number of petals, sepals, or anthers?

All help is greatly appreciated!

Is there any significance of a flower that has a certain number of petals, sepals, or anthers?
Yes there is a great deal of significance to it . let us look at it =





1 ) Dicot flowers have sepals and petals either 5 or 4 in number or in their multiple .





Monocots have them in 3 or multiple of three.

2 ) Presence of free sepals ; petals ; stamens and carpels is a primitive character and found in the most primitive flowering families such as Magnoliaceae ; Annonaceae.





United or fused floral parts mentioned above is considered to be an advance character and found in advanced families ( There are many ) Asteraceae is one of them.





I do not know what more you expect besides this . Othewise I would have continued .

Good cheap, household materials to make a model of a flower and its parts out of?

I need to make a model of a flower and its parts (petal, stamen with anther and filament, sepal, ovule, and pistil with stigma, style, and ovary). I tried clay but it didn't work at all. So I need some good cheap household materials and instructions if possible on how to make them. Thanks!

It can be done and what comes to my mind is a hanger! You know the bendy silver ones. You can make the stem, twist hanger around to shape leaves. Maybe use candel wax to add petals as an effect which will wtick to the hanger once it cools down. While the candel wax is hot - cut green material and place i on the wax which will be the effect of the leaves etc %26amp; work from there. Hope this helps!! :)
Reply:You need some craft glue, cardboard, and pipe cleaners. Bend the pipecleaners into a stem with a substantial amount folded at both ends of the pipecleaner. Glue one end to a peice of cardboard for the bottom of the stem to make the 'ground'. Take another pipe cleaner and bend it into a couple of loops, now squash the loops right next to each other loop to make the petals. If you need to, grab another pipecleaner and twist the end to the end of the other "petals" pipecleaner. When you have something resembling the petals of a flower twist the end of the pipecleaners around each other and fold it underneath the flower petals to make a base which you need to glue onto a piece of cardboard circle. Make the circle around 4 1/2 inches in diameter. Now glue this circle (with the petals attatched) to the bent over end of the 'stem' pipecleaner. Draw a small circle on this cardboard base to represent the ovary. The stamen will be a bit tricky, but if you can find some wire, cut tiny lengths and simply stick them through the cardboard sitting under the petals. Hows that? Goodluck
Reply:Cotton buds could do the anther and filament - five cotton buds and paint them yellow should be easy enough.





Petals could just be card, you might be able to cut up a colourful bottle top if you're feeling adventurous, but I can't think of how to stick it down... hmm, actually, you got any blue tack?





The stem could be a garden stick, you know the little green ones? About 5 mm square rods could be the stem and it should be tough enough to hold up the rest. If you don't have that then just find a green pencil, and again, use blue tack or plasticine to hold it in place.





The sepal could just be green card again, wrapped around your pencil.





The fiddly bit in the middle is harder - may I recommend plasticine? Use different colours to get the ovule and ovary and all that.





Good luck, and have fun!
Reply:Dear Erika,





I think that petals and leaves could be made of paper which you color or paint in appropriate colors. The stem could be of wire wrapped with paper. If you have any of those tiny wires used in telephone connections, they could be used to make the stamen, perhaps with a small wad of tissue at the end. The pistil form would depend on what kind of flower you are making, but a wad of tissue at the bottom, center of the stamens might work.

Where is the stamen from the apple flower in the apple iteself? (I DON'T MEAN SEPAL)?

My Biology teacher is asking me this and I can't find it in my notes, so I looked online. However I can't find it there either. Is she simply making things up???

Where is the stamen from the apple flower in the apple iteself? (I DON'T MEAN SEPAL)?
The flowers have many parts that are crucial to the formation of apples:





• Sepals - five green, leaflike structures that make up a flower's calyx


• Petals - the part of a flower that attracts insects by their color and scent


• Stamens - the male reproductive part made up of an anther and filament


• Anther - the part of the stamen that produces pollen


• Filament - the stalk of the stamen


• Pistil - female part of the flower, made up of a stigma, style, and an ovary


• Stigma - the top of a flower's pistil


• Style - the part of a pistil that connects the stigma and the ovary


• Ovary - the rounded base of the pistil, inside of which are five compartments each containing two ovules, female reproductive cells that can become seeds
Reply:The ripened ovary becomes the fleshy apple containing the fertilsed ovules (seeds - apple pips). The petals and sepals fall away.


The shrivelled remains of stamens sometimes stay attached to the fruit. This is the little crispy bit at the opposite 'end' to the stalk.
Reply:the stamen has wilted and died. the spermatozoa has fertilized the ovum and endosperm... nothings left..








maybe...





and for some apple, there is some stamen, left at the bottom side of the apple, which are looked like a little black hair.


What type of windflower has 13 of 14 petals/sepals?

Im trying to classify this flower and i had put it down as a windflower. Now Im trying to find the species and all the windflowers i see have only like 5 petals. Whats my problem?


The petals are much long than they are wide, and are kind of overlapping each other. It has a green center and many anther sticking up in the middle. Any help is welcome. I found this flower in central texas

What type of windflower has 13 of 14 petals/sepals?
Your description sounds like the Anemone...some types have numerous overlaping petals:

BTW, There's even an Anemone called the "Texas Anemone", but that one only has 10 petals. "Several species of anemones grow in Texas, including ten-petal anemone, which is also called Granny's night-cap and windflower, A classical myth connects the creation of this flower with the west wind: "

What is the purpose of the sepals on an apple tree?

I need help with this as best as you can.


Also besides the sepals protecting the outer.

What is the purpose of the sepals on an apple tree?
Hi,





Sepals are usually green "leaf-like" parts that encase the developing flower bud. As the flower matures, the sepals open and usually remain attached to the base of the flower.





The main purpose of sepals on any plant is to protect the flower while it is developing. A secondary purpose of colored sepals in the flowers of some plants is to attract pollinators, as petals do.





I hope this helps.

Reply:Sepals also aids attraction for pollinators because sometimes the osmophores are present there.
