Elaiosomes contain chemicals that attract ants and stimulate them to carry the seeds back to the nest where the elaiosome is consumed leaving the seed to germinate in the environmentally nutritious and safe surroundings of the ant nest.

What seeds have Elaiosomes?
Elaiosome
- Afzelia africana seeds bearing orange elaiosomes.
- Trillium recurvatum seeds.
- Caruncle.
- Carunculate seeds of Ricinus communis (Castor beans)
Why do seeds need to be dispersed?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
What is Caruncle in seed?
The caruncle is the spongy outgrowth of the integument near micropyle. The main function of caruncle is to absorb water which is necessary for germination. The example of seed which contains caruncle is castor seeds. So, the correct answer is 'Outgrowth of integument near micropyle'.
What is the function of the Elaiosome?
The main elaiosome function in seeds is to aid dispersal. For a seed to have the best chance of germinating, sprouting, and surviving into a mature plant, it needs to travel a good distance from the mother plant. Ants are great at dispersing seeds, and the elaiosome serves to entice them.
What is the function of Caruncle in plants?
The caruncle is a structure present in the micropylar region of Euphorbiaceae seeds. This structure has the ecological function of promoting seed dispersal by ants (myrmecochory), but it is debated whether it also has an agronomical importance influencing seed germination.
What are the four ways that seeds can be dispersed?
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
What are the disadvantages of seed dispersal?
New plants to grow, seeds need to be distributed to different areas away from the parent plant avoid!, you 're actually allergic to plant sperm plants because seed dispersal • this encourages aforestation because plants grow other. Spines to cling onto the fur of animals as they brush past the plant, water, animals.
What is the best strategy for seed dispersal?
Strategies for seed dispersal: Animal
Making their seeds food. a. Seeds can be embedded in fruits. Fruits have bright colors and nutrient rich flesh that attract animals like birds and mammals to eat them. The animals then disperse the seeds when they defecate or spit them out.
What is a Caruncle in medical terms?
Medical Definition of caruncle
: a small fleshy growth specifically : a reddish growth situated at the urethral meatus in women and causing pain and bleeding — see lacrimal caruncle.
What is the meaning of Caruncle?
Caruncle (from Latin: caruncula, 'wart') may refer to: Caruncle (bird anatomy), a small, fleshy excrescence that is a normal part of an animal's anatomy. Caruncle, an elaiosome (fleshy structure attached to the seed), especially in the plant family Euphorbiaceae.
Which are the example of Perispermic seeds?
The perisperm is the nutritive tissue of a seed derived from the nucellus and deposited external to the embryo sac —distinguished from endosperm. Some examples of perispermic seeds are Sugar beet, coffee, and black pepper.
