What is Turions in biology?
What is Turions in biology?
Turions or winter/overwintering buds are vegetative, dormant storage organs formed by perennial aquatic plants. They are formed in subtropical to polar zones in response to unfavourable ecological conditions, usually at the beginning of autumn. In this way, fragile shoots of aquatic plants avoid freezing and damage.
What is the meaning of Turions?
: a scaly shoot (as of asparagus and some duckweeds) developed from a bud on a subterranean or submerged rootstock.
What does Antherozoid mean?
Definitions of antherozoid. a motile male gamete of a plant such as an alga or fern or gymnosperm. synonyms: spermatozoid. type of: gamete. a mature sexual reproductive cell having a single set of unpaired chromosomes.
Is turion used for vegetative propagation?
Another important vegetative propagule in aquatic plants is the turion. These morphological variations are found among temperate aquatic macrophytes that overwinter by the formation of winter buds (turions). Many submersed plants persist for years by this means, without a sexual cycle.
What is Perennation in plants?
The process of living through a number of years (as a perennial plant).The ability to survive past the four seasons of a year, usually where there is reduced activity in the organism over the colder months.perennation. survival of a plant for a number of years.
What are bulbils give one example?
define bulbils:- A condensed auxiliary bud (vegetative) is called bulbil. It helps in vegetative reproduction. e.g., Dioscorea, Glabba, Agave, Oxalis. a small bulblike organ of vegetative reproduction growing in leaf axils or on flower stalks of plants such as the onion and tiger lily.

How do you do air layering?
Air layering is pretty simple. You need moist sphagnum moss to wrap around a wounded section of the stem. Wound an area in the middle of a branch by peeling the bark away, then wrap the moss around the cut and secure it with floral ties or plant twine. Cover the entire thing with plastic wrap to conserve the moisture.
What is called perennation?
The process of living through a number of years (as a perennial plant).The ability to survive past the four seasons of a year, usually where there is reduced activity in the organism over the colder months.perennation.
What is the function of petiole?
A petiole attaches the leaf to the stem and contains vascular tissue that provides a connection from the stem to permit sap to enter the leaf and the products of photosynthesis (carbohydrates) to be transported from the leaf to the rest of the plant.
