because some of the cones are male cones, and some of the cones are female cones. the male cones produce the pollen and sperm, and the female seeds contain the seeds.

In gymnosperms the female cones produce?
Megasporangium
What grows inside the seed cone?
The female cones on the plant grow an ovule at the inside base of each scale on the cone. The male cone co. Rains the pollen also known as the sperm cells. When the female cone matures it opens, allowing the pollen to enter for fertilization.
What are all example of cone bearing plants?
Some pine trees and Pine cones.
Which seeds have cyanide on them?
Most deciduous fruit seeds contain cyanide for example: almonds, plums, apples, pears, apricots and many more
Are cinder cones usually found at the edge of large volcanoes?
Yes, although technically, strato-volcanoes *are* cinder cones (composite cones), built up of layers of ash. But the term "cinder cones" (ash cones) is usually applied to smaller cones that form within the vicinity of large volcanic calderas, such as Crater Lake in Oregon. They may be associated with either strato-volcanoes or shield volcanoes.
What plants are gymnosperm?
Gymnosperms are plants that have seeds, in the form of seed pods or cones. Some types are ginkgo, pine, and cypress trees.
What develops into cones?
Volcanoes can form cones. Pine trees have their seeds in cones.
Where do deciduous tree seeds form?
flowers or cones?
How do plants with cones form?
The seeds of flowering are enclosed in an ovary that develops into a fruit, plants with cones, by contrast are members of a group called gymnosperms from the Greek for "naked seeds".
How do conifers prevent self fertilization?
The male cones are located below the female cones on a tree. Also, the timing of cone production varies among trees to ensure that one tree will be producing male cones while another tree produces female cones. This is a form of temporal regulation.
In gymnosperms the female cones produce?
Megasporangium
Where does reproduction take place in gymnosperms?
Gymnosperms (meaning "naked seeds") are seed-bearing plants that don't produce flowers, instead they have male and female reproductive organs mostly in the form of cones. Their microsporophylls release pollen into the air to make available to the ovule, in the megasporophylls causing fertilization. Their seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms. Hope this is helpful!
How does a tree reproduce?
Conifers are non-flowering plants, like a pine cone for example. Another name for them is called a gymnosperm, which is like a naked seed. They reproduce by the pine cone going through mitosis, which creates an egg type thing inside of the conifer which creates a new pine cone.
Is a orange tree a angiosperm or a gymnosperm?
This is angiosperm because it's seed is covered with outer covering shell.
What grows inside the seed cone?
The female cones on the plant grow an ovule at the inside base of each scale on the cone. The male cone co. Rains the pollen also known as the sperm cells. When the female cone matures it opens, allowing the pollen to enter for fertilization.
What does the function of a pine cone on a evergreen tree make?
I think you're a little confused. Pine cones come from pine trees. Evergreens are any plant that doesn't lose its leaves ever year. Not all evergreens are needle leaf trees. Not all needle leaf plants are evergreen. Not all evergreens have cones. And not all plants with cones are pines. But... to answer your question... A cone on a plant (be it a pine, spruce, fir, yew, cedar, redcedar, redwood, larch, or hemlock) is a reproductive organ. Most conifers have separate male and female cones. The male cone has spores that contain sperm. The spores are dispersed by air and land on the female cone (usually of another plant.) After the female cone is fertilized, seeds form.
How are conifers different from ferns?
The word conifer literally means, cone bearing. It refers to trees such as pine trees, which produce pine cones. Such trees are vastly larger than ferns, which are little plants that grow to something like 2 or 3 feet in height at the most. Ferns are also a more primitive form of plant. Trees have trunks made of wood, ferns do not have woody stems. Trees reproduce by means of seeds, ferns reproduce by means of spores (which are like seeds only smaller).
