Why do mosses need water for fertilization

Why do bryophyta plants grow in land but need water for fertilization because of which they are called amphibian plants? Nov 30, Explanation: Bryophytes are often termed as Amphibians of plant kingdom. Can be seen in the diagram that sperms are transported via water.

Their flagellated sperm must swim through water to reach the egg. Do bryophytes have stomata? Mosses and hornworts are the earliest among extant land plants to have stomata, but unlike those in all other plants, bryophyte stomata are located exclusively on the sporangium of the sporophyte.

Stomata on leaves and stems of tracheophytes are involved in gas exchange and water transport. Do liverworts have stomata? The leaves of liverworts are lobate green structures similar to the lobes of the liver, while hornworts have narrow, pipe-like structures. The gametophyte stage is the dominant stage in both liverworts and hornworts; however, liverwort sporophytes do not contain stomata, while hornwort sporophytes do.

Do liverworts have seeds? Liverworts are a group of non-vascular plants similar to mosses. They are far different to most plants we generally think about because they do not produce seeds, flowers, fruit or wood, and even lack vascular tissue. Instead of seeds, liverworts produce spores for reproduction. Can bryophytes reproduce asexually? Bryophyte reproduction happens in two ways, like with other plants. Asexual reproduction occurs when a sporophyte releases spores, and sexual reproduction happens when gametes fuse and form a zygote.

When a bryophyte spore settles somewhere, it grows into a gametophyte. Gametophytes are green and leafy, but small.

Do bryophytes have seeds? The bryophytes consist of about 20, plant species. Bryophytes produce enclosed reproductive structures gametangia and sporangia , but they do not produce flowers or seeds. They reproduce via spores. Why bryophytes are small in size? It is because Bryophytes are limited in size by their genetically inherited characteristics.

As other experts have commented, Bryophytes' structure limits them in size. When we think about mosses, we usually think about those plants that spontaneously grow on rocks or on wood but you have to think about the fact mosses grow on these spots for a good reason, and the reason is that these spots are moist. Hence, when you want to grow mosses, make sure that the environment is moist enough for them. If you have a garden or if you live in an area that is rainy and humid, you would notice how quickly moss can grow seemingly out of nowhere.

These are the plants that just suddenly pop out on places such as the walls outside of your home, rocks, trees, and anything else that can keep water and moisture. It can be pretty difficult for you to control mosses whenever you have a garden, especially because they usually grow and pop out of nowhere when the conditions are moist enough for them.

That means that, where there is water, mosses will usually grow easily, and that is why you will mostly see them growing during the rainy seasons or whenever you have just freshly watered your garden plants.

But for those who take care of mosses, they can be great plants for terrariums because they add an aesthetic appeal that you rarely get with other plants. And, similarly, you need water or moisture for these plants to propagate and grow even when you are keeping them in a terrarium. Water always plays an essential role when you want to reproduce plants. For the usual flowering plants that make use of seeds, they produce these seeds when male plants produce pollen.

The males release the pollen, which will be carried over in the air to the nearby female plants. And when the females are pollinated, they will produce seeds. For flowering plants that have seeds, you probably know by now that the germination process happens when the seeds are exposed to water or moisture.

Plants will grow from seeds in places that have conditions that are moist enough for them. The difference between mosses and other plants is them not growing and reproduce using seeds, but do so using spores instead. These spores are housed in the mosses brown capsule, which you can find on the seta.

But the brown capsule will only be produced when the male moss sperm reaches the female eggs. The sperm makes use of water to travel to the eggs by swimming all the way to them instead of using air, which is how most plants pollinate female eggs to produce seeds.

After the sperm reaches the eggs, the brown capsule that contains the spores will be formed. And when these spores ripen and are ready to be dispersed, the moss releases them into the air. As the wind carries the spores, they will land on different surfaces that may or may not be suitable for their growth.
