Answer:
Vegetative duplicate is common in Bryophytes. It occurs in the course of favourable growing season. Vegetative duplicate happens only within the gametophytic stage. It takes region via the elements of the vegetative plant or by means of the production of special vegetative propagules.
Science Interview Questions
Question: 25. Describe Alternation Of Generation?
Answer:
Regular heteromorphic alternation of generation takes place in bryophytes. The gametophyte produces haploid gametes. After fertilization the oospore gives upward thrust to diplopod sporophyte.
The sporophyte produces the spores through meiosis. The spores deliver upward thrust to the gametophyte. Thus each sporophyte and gametophyte generations trade with every different frequently.

Answer:
Fic rootless sporophyte of Psilopsida resembles sporangium of Iryophytes. Both have terminal sporangia.
Question: 29. Give Two Differences Between Bryophytes And Pteridophytes ?
Answer:
The sporophyte of Pteridophytes is unbiased. It has root, stem and rentals. But the sporophytes of bryophytes are depending on gametophyte. Vascular tissues are present in Pteridophytes however absent in Bryophytes.
Question: 30. What Is Homologous Theory About Evolution Of Bryophytes?
Answer:
According to this theory, the sporophyte isn’t a brand new shape. It is produced due to the direct change of the gametophyte. Thus sporophyte was part of gametophyte.
Question: 31. Give Occurrence Of Anthoceros. Name Its Different Species?
Answer:
Anthoceros grows on wet soil. They are present in shady locations or in the crevices of rocks. Anthocero.S. Erecrus, A. Himahrvensis, and A. Chumbensis are usually determined in Western Himalayas.
Question: 32. How Does Growth Occur In Bryophytes?
Answer:
The growth happens by means of unmarried apical cell in initial degrees. But mature vegetation have several scattered apical cells at the margin. So boom takes vicinity at many points. It forms rosette like thallus.
Question: 33. What Are Gemmae? Give Their Function?
Answer:
Gemmae are also produced on brief stalks on the upper surface of the thallus. These are also act as vegetative reproductive bodies.
Gravitational Interview Questions
Question: 34. What Structure Are Produced By The Division Of Endothelium And Amphithecium ?
Answer:
The cells of the endothecium divide to shape columella. The cells of the columella are arranged in a square inside the transverse phase. Cells of the amphithecium divide to provide an outer layer of jacket initials and an inner layer of sporogenous tissue or archesporium.
Question: 35. What Is Apospory? In Which Plant Does It Occur?
Answer:
Certain cells of the sporophyte can grow to be gametophytes immediately under certain conditions. This phenomenon is known as apospory. It produces diploid gametophyte. Apospory occur in Anthoceros.
Question: 36. What Are Paraphylls?
Answer:
The superficial cells of the stem supply upward push to paraphylls. Paraphylls are filamentous outgrowths. They supplement the photosynthetic activities of leaves.
Light Interview Questions
Question: 37. What Are Tubers? Give Their Function?
Answer:
These are changed special underground branches. These are formed at the give up of developing season. They remain dormant all through the damaging conditions.
Question: 38. How Is Fertilization Occurred In Poreila?
Answer:
The neck canal cells and the venter canal cells of mature archegonia degenerate. They shape mucilage-like substance. It exerts pressure and burst the cover cells.
The mucilaginous fluid oozes out of ruptured neck and attracts the sperms. A massive quantity of sperms gather close to the neck. But only one of them passes down and fuses with the egg to shape the oospore.
Question: 39. What Is Rhizome? Give Its Function ?
Answer:
It is horizontal portion and grows underground. It bears 3 rows of small brown or colourless leaves. It also bears rhizoids. The cells are rich in protoplasm and oil globules.
Question: 40. Give Structure Of Leaf Of Polytrichum ?
Answer:
Leaves have vast bases. Leaves in the higher component are inexperienced. But the lower ones are brown. Each leaf has a wide, colourless sheathing leaf base and slim distal limb. The mid-rib bureaucracy the foremost part of the leaf. These leaves own extra photosynthetic tissue inside the form of closely set vertical plates of inexperienced cells.
These are referred to as lamellae. Green lamellae act as additional photosynthetic tissue.
Bacteria Interview Questions
Question: forty one. What Is Archognial Head?
Answer:
The flask-fashioned archegonia are borne on the apices of leafy stems. Archegonium is surrounded by way of perichaerial leaves. These leaves overlap to form a closed bud-like shape. The archegonia occur in cluster of three to six.
Question: 42. What Is Peristome? Give Its Function ?
Answer:
Peristome is gift in the form of a thick rim. It bears a number of inflexible teeth. The epiphragm fills the distance within the ring of peristome teeth and is connected to their hints. Peristome enamel stand up from the rim or diaphragm.
Asia Interview Questions
Question: forty three. How Are Spores Dispersed In Polytrichum?
Answer:
Cells of the epiphragm dry up at some point of dry conditions. It separates the operculum. The calyptra falls. Epiphragm additionally dries up between the peristome pores. The crucial tissue of theca vicinity except the spores degenerates. Thus the spores lie unfastened in the centre of the capsule at adulthood. Spores pop out via pores. They are dispersed with the aid of wind.
Question: forty four. What Are The Main Characteristics Of Bryophytes?
Answer:
Bryophytes are nonvascular plant life, that means that they do not have accomplishing tissues and carry out the shipping of water and nutrients thru diffusion. They are cryptogamic, or instead, they do not present plant life or seeds; they are small in length; they gift water-dependent fertilization; in their existence cycle, the lasting form is haploid (the gametophyte) and the sporophyte depends on the gametophyte to survive.
Question: forty five. What Are The Main Groups Of Bryophytes?
Answer:
The important agencies of bryophytes are mosses, liverworts and hornworts.
Question: forty six. How Is The Transport Of Substances Carried Out Across Bryophyte Tissues? How Is This Feature Related To The General Size Of These Plants?
Answer:
In bryophytes, there aren’t any water-accomplishing or nutrient-engaging in systems and the shipping of those substances is achieved via cell to mobile diffusion. The small length of bryophytes relates to this feature due to the fact if there are not any undertaking vessels, it isn’t always viable for cells to be too some distance other than every different (the emergence of carrying out tissues in tracheophytes allowed their increase in size).
Question: 47. What Is The Life Cycle Type Of Bryophytes?
Answer:
As in all vegetation, the existence cycle of bryophytes is diplobiontic (the alternation of generations). In bryophytes, the lasting form is the haploid one.
Question: 48. In General, Where Is The Sporophyte Located In Relation To The Gametophyte In Bryophytes? How Does The Sporophyte Obtain Nutrients?
Answer:
In standard, the bryophyte sporophyte is a long, tiny stem that grows at the pinnacle of the gametophyte. The sporophyte depends complelety at the gametophyte to reap vitamins.
Question: 49. Why Can Bryophytes Be Considered The “amphibians Of The Plant World”?
Answer:
Like adult amphibians, bryophytes live within the terrestrial environment however depend on water to reproduce. For this cause, the nickname is justified.
