What is the point at the end of the cone called?
An Apex or Vertex of the cone
What is the side of the cone called?
The curved surface (or face) of the cone.
What is a point of a cone called?
point
What is the figure called formed by the intersection of a right circular cone and a plane that lies parallel to the edge of the cone?
A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
What is the top of a cone called?
The top of a cone, seen from the outside of the cone, is called the vertex, also referred to as the externalpoint.The vertex is the point of intersection of the lines, or generators, of the cone and the plane base, in this case a circle. But if you just call it the point, everyone will know what you mean.This is referring to what we all think of when we hear the term, cone: a right circular cone. There are other types of cone, but probably not of interest here.
What is called when pollen is transferred from the male cone to the female cone in gymnosperm?
germination
Does a male or female cone produce seeds?
The female cone.
Where are angiosperm seeds often found?
Angiosperm seeds are found inside the female cones. The cone is called a strobilus. The male cones distribute 1-2 million pollen grains. The female cones have a sticky secretion that catches the pollen and brings it into the female cone.
What part of a female cone holds the pollen?
The Stigma
How is pollen transferred from the male to the female cone?
By various means, depending on the species. In some, bees and other insects go for the honey and in doing so get pollen on them which they then transfer to another flower when they visit that. In others, wind blows the pollen from the anthers (the male part) to the stigma (the female part). In others, the anthers bend over and touch the stigma. All sorts of methods.
When the wind carries pollen to a female cone what occurs?
Pollination.
What is the reproductive structure of gymnosperm called?
The reproductive structure of a gymnosperm is the cone. The cone produces pollen or sperm cells that will later on fertilize a female plants eggs or anthers
What is the structure that develops into a pollen grain?
First pollen falls from a male cone onto a female cone. In time a sperm cell and an egg cell join together in an ovule on the female cone
What is the structure of a female cone?
The structure of the female cone is the reproductive cone that contains the seeds of the plant. It is also called the Conifer cone.
What is the seed bearing structure of a gymnosperm called?
The cone of a gymnosperm is the equivalent of the ovary of angiosperms. The seeds in the cone are naked, and receive pollen by wind action from the male equivalent of the stamen. In season, you'll often find dustings of sulphur-yellow pine pollen on the surface of water puddles.The gymno part comes from the Greek and means naked, hence similar words such as gymnast.
Are pine cones asexual or sexual reproduction?
They can produce either way. The female conifers reproduce seeds which are held in the cone. The male’s cones produce pollen which is transferred by the wind. When the female cells are ready to unite with the male cells in the pollen, the female cone becomes sticky so it can stick to the pollen. Many conifer seeds have wings so to carry them away from the adult tree in the wind. Hope this helped :)
What are the seeds of a Christmas trees or pine trees called?
Pine trees have cones. There are male cones, which are smaller (about 1-5 cm), and female cones, which are larger (3-60 cm). The male cones contain pollen. The female cones have ovules, which become seeds when fertilized by pollen from a male cone.
