What is the opening to the ovule of a conifer called?
The micropyle
What is the term for the entry of the pollen tube into the ovule through the micropyle?
The term for the entry of the pollen tube into the ovule through the micropyle is "micropylar penetration." This process is essential for fertilization to occur in plants.
Which type of ovule OF pinus have?
pinus ovule is orthotropus unitegmic and three layered.
In ovule formation what happens when the pollen tube does not pass through the micropyle?
If the pollen tube does not pass through the micropyle during ovule formation, fertilization cannot occur because the sperm cells contained within the pollen tube will not reach the egg cell. This will prevent the fusion of gametes and subsequently the development of seeds.
What does ovule do for a plant?
The female reproductive structure that develops into a seed in a seed-bearing plant. An ovule consists of a megasporangium surrounded by one or two layers of tissue called integuments. The megasporangium produces spores that develop into megagametophytes. These megagametophytes remain within the tissues of the ovule and produce one or more egg cells. Sperm from pollen grains enter the ovule through an opening called a micropyle and fertilize the egg cells. The resulting embryo then begins to develop within the ovule, which becomes a seed. Among the conifers and cycads, the ovules are typically found in pairs on scales in the female cones. The ovules of angiosperms are contained in a structure called the ovary within in the flower.
What is the function of the micropyle?
The micropyle opening allows the pollen tube to enter the ovule for fertilization. It absorbs water for germination. It provides for the diffusion of respiratory gases.

What are the differences between helium and micropyle?
Helium is a chemical element with the symbol He and is a colorless, odorless, and tasteless gas. It is the second lightest and second most abundant element in the observable universe. A micropyle, on the other hand, is a small opening in the surface of an ovule through which pollen grains enter for fertilization in plants. It is a specialized structure found in the reproductive organs of plants.

How does a pollen grain travel through the parts of a flower to finally become a seed?
The pollen grain released from the anther lobe during anthesis reaches the stigma by pollination. Thereafter, it germinates on the compatible stigma to send pollen tube to the micropyle of the ovule inside the ovary. The male gametes from the pollen grain are transferred to the embryo sac for fertilization and the ovule is converted into a seed when zygote develops into an embryo.
What is the type of ovule in pinus?
The type of ovule in Pinus is an anatropous, unitegmic, and crassinucellate ovule. This means that the ovule is inverted, has a single integument, and contains a thick nucellus.
A small body in seed bearing plants that contains the female reproductive cells e?
This structure is called an ovule. It is found within the ovary of the flower and contains the female gamete, or egg cell, which can be fertilized by a male gamete to produce a seed.
What is stalk of ovule called?
The stalk of an ovule is called the funiculus. It connects the ovule to the placenta within the ovary of a flower.
