Hence, the correct answer is ‘Vexillary‘.
What is aestivation short answer?
Hibernation or “winter sleep” is the state of inactivity or low metabolic process performed by the animals during winters. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summers.
What is aestivation with example?
Aestivation is the mode of arrangement of sepals or petals in the floral bud with respect to the other members of the same whorl. It is divided into five main types:- A)Valvate Aestivation:-when sepals or petals are arranged in a whorl and just touch margin of one another as seen in Calotropis.
What is meant by aestivation in flowers?
Aestivation (in botanical terms) is the arrangement of sepals and petals in floral buds with respect to other members of the whorl. It is often confused with vernation, which is the arrangement of scales and new leaves in a leaf bud before it opens. The sepals and petals are collectively known as a perianth.
What are the 4 types of aestivation?
The five different types of aestivation are: Valvate Aestivation. Twisted Aestivation. Imbricate Aestivation.
What is aestivation give its types?
Aestivation is defined as the mode of arrangement of either sepals or petals in a floral bud. The following are the various types of aestivation found in petals: Valvate aestivation. Twisted aestivation.
What is aestivation class 12th?
Aestivation is the arrangement of accessory floral organs, that is sepals and petals in relation to one another in the bud condition. It is of four types- open, valvate, twisted and imbricate.
What is hibernation and aestivation?
Aestivation and Hibernation is one of them. Hibernation is winter sleep whereas aestivation denotes summer sleep. This sleep is different from the normal sleep on other days. During both periods of sleep, the animals chose to have low metabolic activity to restore their body temperature and their energy as well.
Who discovered aestivation?
The aestivation hypothesis is a hypothesized solution to the Fermi paradox conceived in 2017 by Anders Sandberg, Stuart Armstrong and Milan M. Ćirković.
What is aestivation Mcq?
Solution(By Examveda Team)
Aestivation is summer sleep and during aestivation, animals usually tend to rest in a shady and cool place. They take sleep during the hot hours of daytime. Hibernation is a winter sleep and in this sleep, an organism tend to pass the time in dormant conditions.
What is aestivation explain with diagram?
Aestivation means arrangement of accessory floral organs(sepals or petals) in relation to one another in a flower. Some types of Aestivation: Open: Margins of adjacent petals are not overlapping / touching others.
What is aestivation adaptation?
Aestivation is generally defined as a type of dormancy, which is a survival strategy used to sustain lack of food and other extreme conditions (Pinder et al., 1992; Abe, 1995; Storey, 2002). Animals that aestivate become inactive and stop feeding in response to warm temperatures.
What animals use aestivation?
The animals that undergo aestivation include earthworms, frogs, bees, snails, salamanders, tortoises, and crocodiles. Hibernation aids in regulating the body temperature and helps in avoiding any damage to the body due to the low temperature.
What is aestivation how many types of aestivation are there?
Aestivation is the mode of arrangement of sepals or petals in a floral bud with respect to the other members of the same whorl. There are four main types of aestivation.
What is aestivation class4?
Aestivation is summer sleep and during aestivation, animals usually tend to rest in a shady and cool place. They take sleep during the hot hours of daytime. Among many animals who perform aestivation are, frogs, earthworms, snails, crocodiles, lizards, tortoise and many more.
What is twisted aestivation?
In Twisted Aestivation, one edge of a petal covers the adjacent petal, while the other border is covered by another petal. The margins of one petal overlap those of the next, and the margins of the next overlap those of the next. Example: Ladyfinger, Hibiscus, Cotton, and China rose.
What is aestivation Class 11 zoology?
In zoology, although hibernation relates to dormancy and during winter months, aestivation refers to a situation in which some animals during the humid, arid season go into dormancy or lack of movement.
In which type aestivation is twisted?
Malvaceae
Twisted aestivation is found in Malvaceae and has flowers like Hibiscus, Malva, or in china rose. Aestivation also helps in detecting the sex of the plant.
What is Placentation Class 11?
Placentation is defined as the arrangement of the placenta in the ovary of a flower. The placenta connects the ovules with the wall of the ovary.
What is hibernation give example?
Hibernation is a type of deep sleep some animals (like bears) go into during winter. Hibernation is like a long nap. Have you ever wanted to skip from fall to spring? Some animals do just that by hibernating, which is a sleep-like state during which their metabolism slows and they conserve energy.
What is the difference between hibernation and aestivation and diapause?

Difference Between Diapause and Hibernation.
| Difference Between Hibernation and Diapause | |
|---|---|
| Diapause | Hibernation |
| Diapause is commonly observed in insects. | Hibernation is common among higher animals as well as invertebrates such as arthropods. |
