Gametophyte dependent on sporophyte
Websporophyte generation The term for the body of a bryophyte such as Marchantia is thallus Botanically, a seed is a structure developed from a (n) ovule The small heart-shaped gametophyte called a prothallus is part of the life cycle of the ferns The vascular tissue by which nutrients are transported throughout ferns is called phloem WebThe short, blue-green gametophyte is the dominant phase of the lifecycle of a hornwort. The narrow, pipe-like sporophyte is the defining characteristic of the group. The sporophytes emerge from the parent gametophyte and continue to grow throughout the life of the plant (Figure 4). Stomata appear in the hornworts and are abundant on the …

WebThe sporophyte is attached to and dependent on the gametophyte. (By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid … The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a … See more A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase.

WebThe gametophyte is typically upright with dichotomous branching and small leaf-like appendages, or in liverworts it may be flattened and thalloid. The unbranched sporophyte is born on the gametophyte and produces a single terminal sporangium. Bryophytes mostly inhabit shady and humid environments.
