The pollen tube is a structure designed to help a particle of pollen, the male side of the plant fertilization process, to access the egg cell in the female part of the plant. The egg cells are typically protected by cell walls and shells designed to keep them in place and protect them from outside elements. Pollen particles create pollen tubes to reach through these walls and access the egg cell.

Describe how a pollen tube carries speem to the ovule inaflower?
In flowering plants, after pollination, a pollen grain germinates on the stigma, forming a pollen tube. This tube grows down through the style toward the ovule, guided by chemical signals. As the pollen tube extends, it transports sperm cells from the pollen grain to the ovule, where fertilization occurs, leading to the development of seeds. The successful delivery of sperm to the ovule is crucial for reproduction in flowering plants.
What is a matured ovule?
A matured ovule is a structure found in the ovary of a flowering plant that contains the female reproductive cells. It develops into a seed after fertilization by pollen.
Where does germination of the pollen grain occur in flowering plants?
Germination of the pollen grain typically occurs on the stigma of the carpel (female reproductive organ) in flowering plants. The pollen grain produces a pollen tube through which the male gametes travel to fertilize the ovule.
What produces the ovule?
ovary
What is the function of tube nucleus?
The tube nucleus is a specialized structure found in the pollen grain of flowering plants. Its primary function is to guide the growth of the pollen tube during fertilization. Once the pollen grain lands on a compatible stigma, the tube nucleus directs the formation of the pollen tube, allowing sperm cells to travel to the ovule for fertilization. This process is crucial for the successful reproduction of flowering plants.
What is an egg in a female plant structure?
In flowering plants, the egg is called the ovule and is found in the ovary, usually at the base of the pistil.

In flowering plants what is the female gameophyte?
The ovule held within the ovary
Function of an ovule in a plant?
This is from wikipedia. Check out the article by clicking on the related links below.Ovule literally means "small egg." In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: The integuments forming its outer layer, the nucellus (or megasporangium), and the megaspore-derived female gametophyte (or megagametophyte) in its center. The megagametophyte (also called embryo sac in flowering plants) produces the egg cell for fertilization. After fertilization, the ovule develops into a seed.
What is a matured ovule?
A matured ovule is a structure found in the ovary of a flowering plant that contains the female reproductive cells. It develops into a seed after fertilization by pollen.
Where is the megasporocycle located in?
The megasporocycle, also known as the megasporangium or ovule, is located within the ovary of flowering plants (angiosperms) and in the cones of seed plants (gymnosperms). It is the structure that produces megaspores through meiosis, which eventually develop into female gametophytes. In flowering plants, the megasporocycle is typically found within the ovules contained in the ovaries of the flowers.
The multicellular structure in seed plants in which a megagametophyte develops from a megaspore?
ovule
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 the part of a flowering plant which develops from an ovule after fertilization?
The fruit which contains the seeds usually develops from an ovule after fertilization.
What is a flowering seed?
A seed flower is called an ovule
Is the embryo sac male or female?
The embryo sac is female, as it is the structure within the ovule of a flowering plant that contains the female reproductive cells (eggs).
