Examples of micropyle
micropyle
The receptive part of the gymnosperm ovule is called the micropyle.
From the en.wikipedia.org
The gametophyte cell closest to the micropyle opening of the embryo sac develops into the egg cell.
From the en.wikipedia.org
The gap in the integuments through which the pollen tube enters to deliver sperm to the egg is called the micropyle.
From the en.wikipedia.org
In non-flowering seed plants, pollen germinates in the pollen chamber, located beneath and inside the micropyle.
From the en.wikipedia.org
Alternatively, the gymnosperm male gametophytes are carried by wind to a female cone and are drawn into a tiny opening on the ovule called the micropyle.
From the en.wikipedia.org
In a favorable situation, an opening called the micropyle appears and releases amoebocytes, which differentiate into cells of all the other types.
From the en.wikipedia.org
Ovules are typically positioned so that the micropyle is facing the point of funiculus attachment, but other positions are found in a variety of plant groups.
From the en.wikipedia.org
The most important and useful features for identifying eggs are the size, length, and width of the plastron, as well as the morphology of the plastron in the area around the micropyle.
From the en.wikipedia.org
The upper or chalazal pole becomes the main area of growth of the embryo, while the lower or micropylar pole produces the stalk-like suspensor that attaches to the micropyle.
From the en.wikipedia.org
- Minute opening in the wall of an ovule through which the pollen tube enters
- Ovule literally means "small egg." In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. ...
- The end of the embryo sac where the egg cell and synergids are located.
- On the surface of the egg, there is a small indention with a miniscule hole known as the micropyle. This hole allows for the developing embryo inside to respire.
- The small canal through the integuments (outer layers of tissue) of an ovule, usually at the point furthest away from the funicle (ovule stalk), persisting as a pore in the seed coat.
- In nematodes: A minute opening in the membrane of an egg through which the spermatozoa enter. (14)
- The opening or mark in the integument of a seed indicating the position of the foramen of the ovule.
- The opening in a ripe seed through which moisture may enter prior to germination.
- Found in the eggs of certain organisms such as the fruit fly, a small channel through the chorion at the anterior end of the egg that provides an entryway for sperm at fertilization.
