When do sac fungi form dikaryotic hyphae?
Sac fungi form dikaryotic hyphae during the sexual stage of their life cycle, which occurs after the fusion of two compatible mating types. This leads to the formation of dikaryotic mycelium, where each hyphal compartment contains two genetically distinct nuclei in separate but synchronized compartments.
Is the gametophyte stage the dominant stage in a gymnosperms life cycle?
No, the sporophyte stage is the dominant stage in the gymnosperm life cycle. The gametophyte stage is reduced and dependent on the sporophyte for nutrition and support.
Which stage is not part of the four stage life cycle?
The four-stage life cycle typically includes the stages of introduction, growth, maturity, and decline. A stage that is not part of this life cycle is "stagnation," which refers to a period where growth halts but is not officially recognized as a distinct stage in this model. Instead, stagnation may occur during the decline phase or as a characteristic of the maturity stage.
What is the dominant stage of the life cycle in primitive plants?
The dominant stage of the life cycle in primitive plants, such as mosses and liverworts, is the gametophyte stage. This is where the plant produces gametes for sexual reproduction. The sporophyte stage is smaller and dependent on the gametophyte for nutrition.
What are produced in the sporophyte stage of a plant life cycle?
spores

What is the dikaryotic stage?
The dikaryotic stage is a phase in the life cycle of certain fungi, particularly within the phylum Basidiomycota and Ascomycota. During this stage, two genetically distinct nuclei coexist in a single cell, resulting from the fusion of compatible hyphae without immediate karyogamy (nuclear fusion). This stage is important for the development of the fruiting bodies, where the nuclei will eventually fuse to form a diploid zygote, leading to spore production. The dikaryotic phase allows for genetic variation and the adaptation of fungal populations.
Does a moth have 3 - stage life cycle or 4 - stage life cycle?
A moth has a four-stage life cycle: egg, larva (caterpillar), pupa (chrysalis), and adult. This is known as complete metamorphosis and is characteristic of many insects, including butterflies.
What is the difference between dikaryotic and diploid?
Dikaryotic refers to a stage in the life cycle of fungi where two genetically different nuclei coexist within the same hyphal cell, while diploid refers to cells with two sets of chromosomes, commonly found in organisms with sexual reproduction. Dikaryotic cells have a unique genetic arrangement that allows for genetic diversity and adaptation, while diploid cells are formed by the fusion of two haploid cells during fertilization.

Is the gametophyte stage the dominant stage in a gymnosperms life cycle?
No, the sporophyte stage is the dominant stage in the gymnosperm life cycle. The gametophyte stage is reduced and dependent on the sporophyte for nutrition and support.
What is the life cycle of fungus gnats?
A 28- to 36-day life cycle during which there is progression through four (4) life stages is what characterizes the life cycle of fungus gnats (Bradysia spp).Specifically, the adult female deposits as many as 120 eggs in batches of no more than 30 at a time 8-10 days after mating. Within 4-6 days, the eggs hatch into slender, legless larvae with white bodies and black heads. In 12-14 days, the larvae move into the pupa stage. The fourth and final stage is the adult.
What stage of product life cycle is the smartphone?
Growth stage
Which life cycle stage is found in plants but not animals?
The alternation of generations is a life cycle stage found in plants but not in animals. This stage involves a switch between a multicellular haploid stage (gametophyte) and a multicellular diploid stage (sporophyte) in the plant life cycle.
What is a three-stage life cycle?
it is basically an insect that has 3 stages of life cycle.
