Gametophyte Is Totally Dependent On Sporophyte In Which Plant Group?

  • Both gymnosperms and angiosperms have gametophytes that are dependent on sporophytes for their survival.
  • The hibiscus is a plant that produces flowers (angiosperm).
  • Because the sporophytic generation is not photosynthetic, bryophytes like Polytrichum and Marchantia are examples of bryophytes in which the sporophyte is dependent upon the gametophyte.

The sporophytic generation receives its nutrients from the gametophyte.

In gymnosperms and angiosperms, the gametophyte is wholly reliant on the sporophyte for its existence. In pteridophytes, the gametophyte is an autonomous phase of the life cycle, although it is not the phase that predominates.

Are gametophyte and sporophyte independent of each other?

In which of the following categories are gametophyte and sporophyte not reliant on one another? Bryophytes are a group of non-vascular land plants that survive in damp environments and have a multicellular diploid sporophyte that lives as a parasite on an independent multicellular haploid gametophyte that produces multicellular jacketed sex organs. Bryophytes are classified as bryophytes.

What is the gametophyte generation in plants?

  • After being fertilized, the egg will eventually grow into a seed, which will mark the beginning of a new generation of sporophytes.
  • Megaspores that contain embryo sacs are the building blocks of the female gametophyte generation.
  • Microspores and pollen are the components that make up the male gametophyte reproduction.

The plant body and the seeds together up what is known as the sporophyte generation.

What does sporophyte generation consist of?

The plant body and the seeds together up what is known as the sporophyte generation. In a process known as alternation of generations, the gametophyte phase and the sporophyte phase of a plant’s life cycle take turns occurring in the plant’s life cycle. Because gametes are created during this stage of the life cycle, the gametophyte is representative of the sexual phase of the life cycle.

What happens in the gametophyte phase of reproduction?

The creation of a diploid zygote by means of sexual reproduction marks the conclusion of the gametophyte phase in plant life. The sporophyte phase of plant development, represented by the zygote, is made up of the creation of plants that have diploid cells. When the diploid sporophyte cells undergo meiosis, which results in the production of haploid spores, the cycle starts once more.

Is gametophyte dependent on sporophyte in pteridophytes?

They derive their nourishment from the parent gametophyte even after they have grown straight from the fertilized egg that is located in the archegonia neck (which later develops into the calyptra). Therefore, choice C is the one to go with.

Which group gametophyte is depend on sporophyte?

In bryophytes, the sporophyte must have the gametophyte in order to survive.

Is sporophyte dependent on gametophyte in bryophytes?

On the other hand, the gametophyte of the vast majority of vascular plants is dependent on the sporophyte. The gametophyte of bryophytes is the generation that lives the longest and is most noticeable, but the sporophyte of vascular plants is the generation that holds this distinction.

Is gametophyte dependent on sporophyte in seed plants?

The development of gametophytes in plants that produce seeds In plants that produce seeds, such as angiosperms and gymnosperms, the creation of microscopic gametophytes is wholly dependent on the generation of sporophytes. The sporophyte generation of flowering plants is responsible for the production of both male and female spores.

Is gametophyte dependent on sporophyte in angiosperms?

The sporophyte of seed plants (gymnosperms and angiosperms) is green and photosynthetic, whereas the gametophyte is dependent on the sporophyte for food.

Is sporophyte dependent on gametophyte in mosses?

The stages of a moss’s life cycle (genus Polytrichum). The nutritional needs of the sporophyte generation are provided by the gametophyte generation, which is responsible for photosynthesis. Meiosis is carried out in the cells that are contained within the sporangium of the sporophyte in order to create male and female spores, respectively.

Which plant has dependent sporophyte?

Mosses, liverworts, and hornworts are all examples of bryophytes, which are plants that have a dominating gametophyte phase, which the adult sporophyte depends on for their sustenance.

In which group gametophyte is depend on sporophyte a algae b bryophyta C moss D Gymnosperm?

(E) Within the sporangia that are found on the sporophyte of gymnosperms, both male and female gametophytes can be found.

Which has independent gametophyte and sporophyte?

The answer that you are looking for is pteridophytes.

Is sporophyte free living in pteridophytes?

In bryophytes such as Marchantia and Funaria, the primary plant body is an independent gametophyte, whereas the sporophyte is either completely or partially dependent on gametophytic reproduction. The gametophyte phase of the life cycle is often autonomous in pteridophytes (like Pteris), but the sporophyte phase is the more dominant of the two.

Do pteridophytes have independent gametophyte?

Whereas in pteridophytes, the primary plant body is a sporophyte that is differentiated into genuine root, stem, and leaves, and the gametophyte is typically tiny or inconspicuous, it is still an autonomous structure.

In which of the bryophyte sporophyte is partially dependent on gametophyte?

It is possible that the bryophyte’s sporophyte is wholly or partially reliant on the gametophyte for its own survival. The sporophyte of the bryophyte relies on the gametophyte for either all of its anchoring or some of its sustenance. This dependence can be either complete or partial.

Is gametophyte dependent on sporophyte in gymnosperms?

In gymnosperms and angiosperms, the gametophytes are dependent on the sporophytes in order to reproduce. Gymnosperms are plants that do not produce flowers but instead generate cones and seeds. Angiosperms are vascular plants. They are composed of a stem, a root system, and leaves.

Are gymnosperms gametophyte or sporophyte dominant?

In gymnosperms, the sporophyte generation predominates throughout the life cycle. On the sporophyte parent plant, the gametophytes and the future sporophytes that will be produced by the following generation develop.

Why sporophyte is dominant in pteridophytes?

The fertilized egg, also known as the zygote, goes through the process of mitosis to divide and form the various parts of the plant, such as the stems, roots, and sporophyte. Subsequently, spores are produced once more through the process of meiosis and are dispersed by the process of dispersion. Since the life cycle continues, the sporophyte is the dominant phase of the pteridophyte.

Do pteridophytes have independent gametophyte?

Whereas in pteridophytes, the primary plant body is a sporophyte that is differentiated into genuine root, stem, and leaves, and the gametophyte is typically tiny or inconspicuous, it is still an autonomous structure.

What is true for gametophyte of pteridophytes?

In this stage, meiosis is responsible for the production of spores, whereas mitosis is responsible for the formation of gametes in the free-living gametophyte generation. A thallus is the name given to the gametophyte that is generated. It contains male and female genitalia as well as other sexual organs.

Do pteridophytes have free living gametophyte?

The gametophyte is the generation that is free to live and reproduce in bryophytes and pteridophytes alike. The gametophyte is the generation that is free to live and reproduce in bryophytes and pteridophytes alike.

Which has independent gametophyte and sporophyte?

The answer that you are looking for is pteridophytes.
