Where would you find a fern gametophyte quizlet?

Fern sperm use flagella to swim through moisture to fertilize the egg. The small heart-shaped gametophyte grows on or just below the soil level in moist areas. Among living vascular plants, however, the sporophyte (diploid) generation is the larger and more complex plant in the alternation of generations.

Where can gametophyte be found?

The male gametophyte is formed in the anthers of the stamens, and the female gametophyte is located in the ovules within the pistil. In the anther, four pollen sacs (locules) contain numerous microspore mother cells, each of which undergoes meiosis to produce four microspores in a tetrad (Figure 2A).

What is the fern gametophyte?

The fern gametophyte is a small plant that exists as a prolonged intermediate in the fern life cycle, between the germination of a spore and the mature sporophyte. Following its emergence from a spore, it grows from two cells into a distinctively shaped structure containing several hundred cells.

Is fern a sporophyte or gametophyte?

Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.

Which of the following is an example of an angiosperm?

Some common examples of angiosperms include magnolia trees, roses, tulips, and tomatoes. Magnolia trees can be found towering all throughout the southern United States. These trees are prime examples of angiosperms.

Which of the following structures would you find on a fern?

The structure of a fern. Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification. The rhizome is the stem of the fern plant.

What is an example of a gametophyte?

Examples of Gametophytes The fern you imagine when you think of Jurassic Park or a forest floor is a gametophyte. The graceful, fringed leaves are haploid – meaning they have only one set of chromosomes and produce sex cells through mitosis, like all gametophyte plants.

Where are spores found in ferns?

sporangia
Fern spores are the tiny genetic bases for new plants. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves.

Where does meiosis occur in ferns?

Meiosis occurs within sporangia, located on the underside of the sporophyte leaf. After the spores are released they germinate, divide by mitosis and grow into simple heartshaped gametophytes.
