What is the function of elater in the capsule Marchantia sp?
Elaters in the capsule of Marchantia sp. are responsible for aiding in seed dispersal. They help in the dispersal of spores by expanding and contracting in response to changes in humidity, effectively releasing spores into the environment.
In addition to spores what would you expect to see inside a slime mold sporangium?
Inside a slime mold sporangium, you would expect to find the spores already developed and ready for dispersal. The sporangium also contains structures that help in spore dispersal such as a cap or lid that can open to release the spores. Additionally, some sporangia may have specialized cells that assist in the dispersal of spores.
What are Stalks that form pollen?
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
What are examples for dispersal by explosion?
Examples of dispersal by explosion include the dispersal of seeds by plants like touch-me-not (Impatiens) and wood sorrel, as well as the dispersal of fungal spores by fungi like earthstars and puffballs. These organisms use built-up pressure to forcibly expel their seeds or spores to help them spread over a wider area.
What are four advantages the plant gains by the miniaturization of the gametophyte?
their tiny gametophytes can develop from spores retained within the sporangia of the parental sporophyte. this arrangement protects the delicate female (egg-containing) gametophytes from environmental stressesSoD. megaspores for PF students.
What is the study of pollen?
Palynology is the scientific study of pollen grains and spores, including their production, dispersal, and preservation in the environment. It is used in various fields such as botany, ecology, archaeology, and forensics to understand plant evolution, ecological relationships, and environmental changes.
What are the four dispersal methods?
The four main dispersal methods are wind dispersal, water dispersal, animal dispersal, and self-dispersal. Wind dispersal involves seeds or spores being carried by the wind, water dispersal involves seeds or spores being carried by water currents, animal dispersal involves seeds or spores being carried by animals, and self-dispersal involves seeds or spores being dispersed by the plant itself.
What is pollen assemblage?
the mixture of pollen and spores.
Why is the wind a better method of dispersal for spores than seeds?
Wind dispersal is often more effective for spores than seeds due to their smaller size and lighter weight, allowing them to be carried over greater distances with less energy. Spores can be produced in vast quantities, increasing the likelihood of successful dispersal and colonization. Additionally, many spores have specialized structures, like wings or filaments, that enhance their ability to remain airborne, thereby reaching diverse and distant environments. In contrast, seeds are typically larger and heavier, making them less suited for extensive wind-based dispersal.
Do ferns have pollen?
No, ferns do not have pollen. They reproduce with spores.
Give two ways by which pollen grains are scattered?
animal dispersal and wind dispersal
Why is the wind a better dispersal for spores than for seeds?
Spores are lighter (make that less dense).
What are two steps for spores dispersal?
Two key steps for spore dispersal are the production of spores and their release into the environment. First, organisms like fungi, mosses, and ferns generate spores in specialized structures. Then, various mechanisms such as wind, water, or animal movement facilitate the dispersal of these spores, allowing them to settle in new locations where they can germinate and grow.
What do fungi release when they reproduce?
Fungi release spores when they reproduce. Spores are akin to seeds and are responsible for fungi's propagation and dispersal.
What is the function of elater in the capsule Marchantia sp?
Elaters in the capsule of Marchantia sp. are responsible for aiding in seed dispersal. They help in the dispersal of spores by expanding and contracting in response to changes in humidity, effectively releasing spores into the environment.
