In the life cycle of mold when hyphae of different mating types meet each hypha forms a?
When hyphae of different mating types meet, each hypha forms a specialized structure called a gametangium. Within the gametangium, specialized cells called gametes are produced. These gametes eventually fuse to form a zygote, which then develops into a new mold organism.
What is the role of gametangium in plants?
A gametopyte has haploid set of chromosomes whereas a sporophyte has diploid set of chromosomes. A gametophyte produces the gamets ( male & female) and a sporophyte produces spores in the sporangium. Germination of these spores results in the formation of gametophyte plants.
How does reproduction in ferns differ from that in mosses?
Ferns reproduce through spores, which are produced in sporangia located on the underside of fronds. Mosses reproduce through spores as well, but they also have a gametophyte stage where male and female gametes are produced in separate structures called antheridia and archegonia. Ferns do not have a distinct gametophyte stage like mosses do.
Where do zygote of a moss form?
In mosses, the zygote forms within the female gametangium, specifically in the archegonium, after fertilization occurs. The zygote develops into a sporophyte, which remains attached to the gametophyte. This sporophyte eventually produces spores through meiosis, completing the moss life cycle.
Is gametangium present in all land plants?
O yes !

What occurs inside the gametangium?
Meiosis
What are the characteristics of a gymnosperms?
Characteristics of Gymnosperms sporophyte dominant: gametophyte very reduced multicellular female gametangium (archegonium) but no male gametangium (male gametophyte reduced to a few cells and a pollen tube) ovules (modified megasporangium) contain the female gametophyte; after fertilization and formation of zygote, then embryo becomes a seed. no external water required for fertilization vascular cambium leads to secondary growth (wood)

What is the juvenile phase of mosses called?
The juvenile phase of mosses is called the protonema. It is a thread-like structure that develops from a germinating spore and eventually gives rise to the leafy gametophyte of the moss plant.
What are people called who study moss?
Muscology is the study of mosses. Muscologists are people who study mosses.
Mosses that reproduce with gametes are?
haploid. They produce male and female gametes through mitosis in specialized structures called antheridia (male) and archegonia (female). When these gametes fuse, they form a diploid zygote that develops into a sporophyte.
What have structures called rhizoids?
the answer to this question is mosses
Structures in plants that produce the gametes are called?
Structures in plants that produce gametes are called gametangia. In ferns and mosses, the male gametangia are called antheridia, while the female gametangia are called archegonia. In flowering plants, the male gametangia are the pollen grains produced in the anthers, and the female gametangia are the ovules contained in the ovary.
What are the spore bearing structures and club mosses and horse tails in the cones of Gymnosperms called?
The spore bearing structures in club mosses and horsetails and the cones of gymnosperms called strobili.
