This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Several explanations of the term “campylotropous ovule.” an ovule that has been bent and has the micropyle very close to touching the funiculus. ovule is a kind of. a tiny body that develops into a seed once it has been fertilized; it is the location of the plant’s female germ cell.
What is Campylotropous?
: having the ovule curved.
Can you provide me an illustration of a Campylotropous ovule?
An example is Ranunculus. Campylotropous is a condition in which the ovule’s body is curled. As a direct consequence of this, the micropyle and chalaza will not be in a straight line when viewed from above. Examples are Leguminosae members.
What is meant by the term “circinotropous ovule”?
A circinotropous ovule is a specific type of ovule that has a lengthy funicle that forms what is almost a complete circle around the ovule and has a micropyle that points in an upward orientation. In this part of the plant, the cells that will eventually become a seed are generated and stored once they have become fertilized by male cells. the integuments, the micropyle, and the chalaza are the parts.
What does the term amphitropous mean?
amphitropous in American English
(æmˈfɪtrəpəs ) adjective. having an inverted structure, with the stalk attachment at the middle of the ovule and the opening near the bottom of the ovule. possessing a flower ovule that has this inverted structure.
Sexual reproduction in flowering plants is discussed in Chapter 2 of the AP Biology textbook, which covers the several types of ovule.
We found 20 questions connected to this topic.
Is the ovule the female reproductive organ?
Components of the Plant: Flowers
The pistil, which is the female reproductive organ,… The style is what ultimately leads to the ovary, which is the part of the reproductive system that houses the ovules. The female components are known as the pistil, while the male parts are called the stamens. The anther and the filament make up the two components that make up the stamen.
How many different kinds of ovules are there?
The answer is that there are a total of six different types of ovules. They are known as orthotropous or anatropous ovules, anatropous ovules, hemi-anatropous ovules or hemitropous ovules, campylotropous ovules, amphitropous ovules, and circinotropous ovules, respectively. In an orthotropous ovule, the ovule’s body is aligned in a vertical orientation.
What kind of ovule is produced by the capsella plant?
This form of ovule is quite similar to an anatropous ovule; however, the curvature of a campylotropous ovule is less pronounced than the curvature of an anatropous ovule. The Chenopodiaceae family, which includes Pisum and Capsella, is the only one that contains the campylotropous ovule. Hence, the answer that is correct is D.
What exactly is an example of a circinotropous ovule?
Alternative a: A Circinotropous ovule can be found in Opuntia. With this particular variety of ovule, the length of the funiculus grows longer until it encompasses the entire ovule. So, picking this alternative is the best choice…. The funiculus is at right angles to both the micropyle and the chalaza, while the micropyle and chalaza are aligned in a straight line.
What is Anatropous ovule example?
, Orthotropous ovules are characterized by their vertical growth, which places the micropyle on the side of the ovule that is opposite to the stalk. As an illustration, piper, polygonum, and cycas. Ovules that have been entirely turned upside down on their stalks are known as anatropous ovules. Helianthus and Tridax are two such examples. I sincerely hope that it is of some assistance.
Which form of ovule is characteristic of the Cactaceae plant family?
Cactus has an ovule type known as a circinotropous ovule.
What does the ovule contain?
In flowering plants, the organ that is responsible for the formation of seeds is called an ovule. It is produced in the ovary of the flower and is made up of the nucellus, which is guarded by the integuments, precursors of the embryo and endosperm, and the seed coat, in that order.
What function does the ovule serve in the plant?
The ovule is the plant component that, after fertilized, transforms into a seed…. The pollen tube is able to enter and discharge its sperm nuclei into the embryo sac, which is a big oval cell in which fertilization and development take place thanks to a small opening (the micropyle) in the integuments. This opening is called the micropyle.
What exactly is an ovule of crassinucellate type?
Definition. The early stage of development of the megasporophyte is characterized by the presence of two or more cell layers between the megasporophyte and the epidermal cells.
Where precisely is the ovule situated?
In plants that produce flowers, the ovule is found within the gynoecium, which is the female reproductive organ of the flower. The ovary of the gynoecium is responsible for the production of one or more ovules, which later develop into the fruit wall. A structure that resembles a stalk and is known as a funiculus is responsible for attaching ovules to the placenta in the ovary.
In what kind of ovule does the embryo sac become shaped like a horse shoe?
Complete answer: Alternative Amphitropous refers to an ovule in which the nucellus is severely bent along both the upper and lower sides, and the ovule also has a lower basal body. This type of ovule is called amphitropous. During this stage, the ovule will begin to curve, and the embryo sac will begin to take on the shape of a horseshoe.
What does it mean when an anatropous ovule is referred to as an inverted ovule?
Observe that because the funiculus develops unilaterally in this type of ovule, the body of the ovule completely rotates across an angle of 180 degrees. As a result, this type of ovule is also known as an inverted ovule because of its rotation. It is referred to as a “typical angiosperm ovule” by scientists. This is what is meant when people talk about the “resupinate ovule.”
What different kinds of placentation are there?
Placentation can take place in one of five different ways in flowering plants: axile, marginal, parietal, basal, or superficial placentation.
What kind of ovule makes up the majority of the ones seen in angiosperms?
The anatropous ovule, which can only be found in angiosperm, is the most frequent form of ovule. An ovule is a tiny body that is found in plants and is comprised of the female germ cells. During the process of fertilization, this ovule will mature into a seed.
In an anatropous ovule, in which direction does the micropyle extend?
Explanation: The anatropous ovule is the form of ovule that occurs most frequently in angiosperm plants. In this case, the ovule has been turned upside down so that the micropyle and the hilum are now on the same plane, and the micropyle is pointing in a downward direction.
What exactly is an ovule of raphe?
The ridge that results from the junction of the funicle and the body of the ovule is known as the raphe. The structure known as the hilum is responsible for maintaining the connection between the ovule’s body and the funicle.
What do you name an ovule that has reached maturity?
Answer: The term “seed” refers to the mature ovule that results from the fertilization of an ovule.
What is the alternative name for the term ovule?
On this page you will find a list of 16 related words, including synonyms, antonyms, idiomatic expressions, and other words related to ovule. Some of the related words include: seed, egg, flower gametophyte megasporogenesis pollination, embryo, nucellus, amphitropous, anatropous, campylotropous, orthotropous, egg-cell, and anther.
What kind of architecture does the anatropous ovule have?
In angiosperms, the anatropous ovule is by far the most common form of ovule. The following constituents make up the whole: Each ovule grows a funiculus, or stalk, or funicle, inside the ovary as it matures. A tiny stalk known as the funiculus connects the ovule to the placenta in the developing embryo.
Once fertilization has taken place, what happens to the ovule?
After fertilization, the ovule will develop into a seed, which will have a supply of nourishment as well as an embryo that will eventually develop into a new plant. In order to guard the developing seed, the ovary transforms into a fruit. Because the ovary of many flowers, like that of the kiwifruit, has a large number of ovules, the fruit of these flowers typically contains a good number of seeds.
