Option A Blue green algae: Blue green algae or Cyanophyceae reproduce through simple division or fragmentation or non-motile spores. Also, they do not reveal any motile phase during the life cycle. … So, the gametes are non-motile.
Which algae do not have motile gametes in their life cycle?
Rhodophyta or the red algae have no motile flagellated cells during any stages of their life cycle.
Which of the following group do not have any motile gametes in their life cycle?
Red Algae and brown Algae.
In which organisms gametes are non-motile?
Angiosperms produce non-motile gametes.
What are non-motile gametes?
Non motile gametes are produced during sexual reproduction in oogamy process. Oogamy is a form of sexual reproduction. It is a form of anisogamy in which the female gamete is larger than the male gamete and is non-motile.
Are chlorophyceae gametes non-motile?
Option D Green algae: Green algae or Chlorophyceae reproduce by zoospores, which are motile asexual spores with two identical anterior flagella. So, their gametes are not non-motile.
When both gametes are non-motile?
In flowering plants, the gametes are non-motile cells within gametophytes. The form of anisogamy that occurs in animals, including humans, is oogamy, where a large, non-motile egg (ovum) is fertilized by a small, motile sperm (spermatozoon).
What are motile and non-motile gametes?
motile- that have cilia like structures and can move…… non-motile- do not show any movement.
Are male gametes non-motile in bryophytes?
As angiosperms and gymnosperm have non motile male gamete while algae, bryo do have motile..
Which plants produce non-motile male gametes?
The male and female gametes are produced by flowers. Flowers mainly have petals, sepals, stamen, and pistil. Stamen is the male reproductive part and has anther and filament. The anther produces and stores the pollen which is the male gamete and is non-motile.
Are all plants non motile?
Most plants have been considered as non-motile organisms. However, plants move in response to environmental changes for survival. In addition, some species drive dynamic motions in a short period of time.
In which plants non motile male gametes are carried by pollen tubes?
Reproduction in all other gymnosperms and in flowering plants is siphonogamous. Here fertilisation occurs through a pollen tube which conveys the non-motile male gamete to the egg.
In which organisms both types of gametes are motile?
b. Gamete Transfer – in majority of organisms, male gametes are motile and females gametes are non-motile, except in fungi and algae in which both gametes are motile. In simple plants like algae, fungi, bryophytes and pteridophytes water is the medium through which male and female gametes moves.
