Noctiluca is a marine, colourless dinoflagellate. It is a voracious predator and has a long, motile tentacle, near the base of which, its single short flagellum emerges. Monocystis is a microscopic, unicellular endoparasitic protozoan found in the coelom and seminal vesicles of earthworm. As it is an endoparasite, it does not possess any special structure for locomotion.

What is common between vegetative reproduction and apomixis?

Options:
A Both are applicable to only dicot plants
B Both bypass the flowering phase
C Both occur round the year
D Both produce progeny identical to the parent

The correct answer is:
Both produce progeny identical to the parent

Solution:
Apomixis is a reproductive process in plants that superficially resembles normal sexual reproduction, but in which there is no fusion of gametes. The embryos develop simply by division of a diploid cell, the ovule. Hence, the progenies produced are identical to the parent. In vegetative reproduction also, progenies produced are identical to the parent.

Topic: Biology, Reproduction in Organisms, NEET
What is common between vegetative reproduction and apomixis?

Options:
A Both are a sexual method of reproduction
B Both produce progeny identical to the parent
C Both are applicable to only dicot plants
D Both bypass the flowering plant

Both produce progeny identical to the parent

Solution:
Vegetative reproduction and apomixis seem to be the same (both involve getting a "clone" of the parent plant) one is limited to the production of seeds/plantlets from the reproductive structures without the need for fertilization to occur, the other is simply dividing a plant into two or more parts or generating a new plant from something other than the seed/reproductive structure.

What is common in all the three, Funaria, Dryopteris and Ginkgo?

Options:
A Presence of archegonia
B Well developed vascular tissues
C Independent gametophyte
D Independent sporophyte

The correct answer is:
Presence of archegonia

Solution:
In Funaria (bryophyte), Dryopteris (Pteridophyte) and Gingko] (Gymnosperm), female sex organ archegonium is formed. Funaria and Dryopteris lacks vascular bundle and have independent sporophyte, while Gingko have independent gametophyte.
Related Theory
Bryophytes are also called amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. The male sex organ is called antheridium, which produce biflagellate antherozoids and the female sex organ called archegonium is flask-shaped, produces a single egg. The antherozoids are released into water where they come in contact with archegonium and fuses with the egg to produce the zygote. Zygotes produce a multicellular body called a sporophyte, which is not free-living but attached to the photosynthetic gametophyte and derives nourishment from it.
