For example, jacarandas generate a large number of wingless, flat seeds that are dispersed in all directions from the parent plant. The grain pattern of mahogany is more complex. The pod, which is originally closed, opens up to reveal the seeds, which have the appearance and behavior of helicopter rotors as they go through the air in a spiral pattern.
Answer. Pinus, the solution you’re looking for is choice (b). Winged seeds are present in Pinus. In the case of Pinus, a few of the tissues that are located at the surface of the ovuliferous scale remain, and these tissues form a membraneous wing that becomes connected to the seed.
What kind of seeds have wings on them?
Winged Tree Seeds.Some types of plants develop seeds that are attached to papery wings with a variety of different structural configurations to give aerodynamic lift.In their journey to their new homes, seeds twirl, float, and spin in the air as they travel across plains, canyons, and mountain slopes.The pine, the maple, the jacaranda, and the catalpa are all examples of trees that may produce seeds with wings.
Where are winged seeds found in Cycas?
Biology Cycas species A and B both produce seeds with wings. A species of Pinus C A species of Papaver D The answer is none of the above. In Pinus, a portion of the surface tissue of the ovuliferous scale dies off but is replaced by a membrane that forms a wing and remains connected to the seed. The winged seeds are released from the cone when these ovuliferous scales split and fall off.
Why are they called winged seeds?
The name of the phenomenon was inspired by the path taken by the seeds as they traveled through the air after falling from the tree. Spinning jenny, whirligig, whirlybird, and wing-nut are some of the other names that have been given to these flying seeds.
Where do winged beans come from?
New Guinea is the country of origin for the tropical legume plant known as the winged bean (Psophocarpus tetragonolobus), which is also known as the Goa bean, four-angled bean, four-cornered bean, Manila bean, and Mauritius bean. It thrives in places with warm temperatures and high levels of humidity, from the Philippines and Indonesia through India, Burma, Thailand, and Sri Lanka.
Where are winged seeds found?
In Pinus, a portion of the surface tissue of the ovuliferous scale dies off but is replaced by a membrane that forms a wing and remains connected to the seed. The winged seeds are released from the cone when these ovuliferous scales split and fall off. The seeds are carried by wind currents to locations that are quite a distance from the parent plant.
Are Cycas winged seeds?
Option D: Cycas is subject to wind pollination; however, this does not result in the creation of pollen with wings.
Is drumstick an example of winged seed?
The solution you’re looking for is a drumstick. With wing-like extensions that encircle the seed, or extend from one end of the seed, are two sides of the side, and all of which aid wind distribution, the winged seeds are classified as such. The drumstick is an example of a plant that has seeds with winged germination.
What is a winged seed?
Referring to seeds that have extensions that resemble wings that either encircle the seed, are on two sides of the seed, or extend from one end of the seed, all of which help the seed to be dispersed by the wind.
Does Pinus have winged pollen grains?
The right response is option (B), which is Pinus. In Pinus, the pollen grains have wings, whereas in mustard and mango, the pollen grains do not have wings. Winged pollen grains are only found in Pinus. The wind is responsible for pollinating the grains of winged pollen. The wings are extensions of pollen grains that have been spread out.
What plants have wings?
Maple and ash are two types of trees that can produce samaras, which are seeds that only have a wing on one side of the fruit. The tulip tree, the elm, and the birch are all examples of trees that have samaras that develop the wing on both sides of the seed.
How many wings are present in Pinus pollen grains?
It is the expanded outer exine that forms the wings of the pollen, and it is located on two lateral sides. It is a trait that is unique to Pinus and no other species.

In which plants both pollen grains and seeds are winged?
There are pollen grains with winged structures present in Pinus. It is the expanded outer exine that forms the wings of the pollen, and it is located on two lateral sides. It is a trait that is unique to Pinus and no other species.
What is drumstick seed?
It is possible to harvest moringa seeds from the pods of the drumstick tree (Moringa Oleifera) or the moringa plant, both of which are indigenous to Northern India. When moringa seeds are fresh and unprocessed, they have a texture similar to that of delicate beans. However, once the seeds have been dried, they turn tough and begin to resemble little beans.
What type of seeds do drumstick has?
Answer. For instance: (a) the seeds of the drumstick plant have wings so that they may be blown away by the wind to far away regions where they can be disseminated. As a result, the seeds of the drumstick plant have wings.
Why do seeds have wings?
The movement of Seeds Caused by the Wind. Some tall trees bear fruit that contains seeds equipped with rigid wings that enclose the seed and allow the fruit to travel great distances. The wings are twisted and balanced in such a way that when the seed is transported by the wind, it rotates continuously as it travels.
