Does sporophyte dependent on gametophyte?

The sporophyte generation is dependent on the photosynthetic gametophyte for nutrition. Cells within the sporangium of the sporophyte undergo meiosis to produce male and female spores, respectively.

Is the sporophyte independent of the gametophyte or dependent on gametophyte?

Gametophyte Generation in Seed Producing Plants In seed producing plants, such as angiosperms and gymnosperms, the microscopic gametophyte generation is totally dependent upon the sporophyte generation. In flowering plants, the sporophyte generation produces both male and female spores.

Is sporophyte dependent on gametophyte in pteridophytes?

Sporophyte is either completely (or) partially dependent on gametophyte in bryophytes. In pteridophytes, the gametophyte is dominant, while sporophyte is a dependent generation.

Is the sporophyte dependent on the gametophyte in bryophytes?

The bryophytes show an alternation of generations between the independent gametophyte generation, which produces the sex organs and sperm and eggs, and the dependent sporophyte generation, which produces the spores. In most vascular plants, however, the gametophyte is dependent on the sporophyte.

How is a sporophyte attached to the gametophyte?

The zygote, protected by the archegonium, divides and grows into a sporophyte, still attached by its foot to the gametophyte.

Is the frond sporophyte or gametophyte?

While the sporophyte consisted of fronds and rhizomes, the gametophyte has leaflets and rhizoids. Within the gametophyte, sperm is produced within a structure called an antheridium.

Which has independent gametophyte and sporophyte?

Pteridophytes is the right answer.

Is sporophyte dependent on gametophyte in gymnosperms?

In gymnosperms, female gametophytes are entirely dependent on the parent sporophyte for nutrition and protection. The much-reduced gametophyte develops from a megaspore, producing one or more egg cells.

Where is the sporophyte located in relation to the gametophyte in bryophytes How does the sporophyte obtain nutrients?

In general, where is the sporophyte located in relation to the gametophyte in bryophytes? How does the sporophyte obtain nutrients? In general, the bryophyte sporophyte is a long, tiny stem that grows on the top of the gametophyte. The sporophyte depends complelety on the gametophyte to obtain nutrients.

In which of the following the sporophyte is attached with the Gametophytes?

So, the correct answer is, ‘Bryophytes.

What comes first gametophyte or sporophyte?

The mature gametophyte produces both male and female gametes, which join to form a diploid zygote. The zygote develops into the diploid sporophyte, which extends from the gametophyte and produces haploid spores through meiosis. Once the spores germinate, they produce new gametophyte plants and the cycle continues.

Is Protonema a sporophyte or gametophyte?

A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses.
