Does Funaria show protonema stage?
Hint: A protonema is a thread-like chain of cells that forms the earliest stage of the life cycle of mosses. Complete answer: Protonema can be seen in Funaria as it is a type of moss.
In which plant is protonema present?
mosses
The protonema, which grows directly from the germinating spore, is in most mosses an extensive, branched system of multicellular filaments that are rich in chlorophyll. This stage initiates the accumulation of hormones that influence the further growth of newly formed cells.
Is protonema found in Pteridophytes?
haploid and is found in pteridophytes. The predominant stage of the life cycle of a moss (bryophyte) is the gametophyte which consist of two stages. The first stage is the protonema stage, which develops directly from a spore….Protonema is.

What is protonema stage of mosses?
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.
Which of the following stage of Funaria is haploid?
Gametophyte stage
The Gametophyte stage of Funaria is haploid.
Is leafy stage present in Funaria?
The leafy gametophyte is the dominant phase of Funaria as the vegetative body of itself is represented by these leafy gametophores. It has two distinct growth stages, a prostrate filamentous alga-like protonema and an upright gametophore.
What is the meaning of Funaria?
Funaria is a genus of approximately 210 species of moss. Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. The name is derived from the Latin word “funis”, meaning a rope.
What is common in all the three Funaria Dryopteris and ginkgo?
Presence of archegonia is common in all the three, Funria (bryophyte), Dryopteris (pteridophyte) and Ginkgo (gymnosperm).
What is predominant stage?
The predominant stage of the life cycle of a moss is the gametophyte which in turn comprises 2 stages – protonema stage and leafy stage.
Which part of Funaria Sporophyte is haploid?
The main plant body is a gametophyte which is independent and the sporophyte is partially or fully dependent on gametophytic generation. Funaria is a type of Moss commonly called Rope moss or Cord moss. The embryo is haploid.
Which of the following one belongs to gametophytic phase in Funaria?
In Funaria the main plant body is free-living gametophyte (n) which exist in 2 forms i.e. protonema (juvenile gametophyte) and leafy gametophore (adult gametophyte). The leafy gametophyte is the dominant phase of Funaria as the vegetative body of itself is represented by these leafy gametophores.
What is the structure of protonema in Funaria?
In Funaria, spores on germination form a branched, filamentous, multicellular structure. It’s called primary protonema. In it certain colourless separation cells are formed by intercalary divisions. These cells die out and break up the protonema into single cell or many celled fragments.
Can protonema Funaria hygrometrica be used as a lead adsorbent?
Protonema of the moss Funaria hygrometrica can function as a lead (Pb) adsorbent Water contamination by heavy metals from industrial activities is a serious environmental concern.
What is the main plant body of Funaria?
* The main plant body of Funaria is gametophyte and is of two forms. (1) Juvenile form (creeping protonema). (2) Adult form (leafy gametophore). * Protonema is the branched filamentous portion which is produced by germination of spores.
What is the scientific name of Funaria?
Funaria * Funaria is known as common moss or green moss or cord moss. * The main plant body of Funaria is gametophyte and is of two forms. (1) Juvenile form (creeping protonema). (2) Adult form (leafy gametophore). * Protonema is the branched filamentous portion which is produced by germination of spores. It is ephemeral or short lived.
