Sticky secretion on the scales of seed cones traps?
A sticky secretion on the scales of seed cones traps pollen grains. Structure is produced by a pollen grain that lands near an ovule is pollen tubes.
Does the wind often carry pollen from male cones to female cones in gymnosperms?
Yes, the wind can often carry pollen from male cones to female cones in gymnosperms.
Where are the reproductive parts of an angiosperms located?
flowers
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
A conifer that has both male and female cones will produce many more pollen grains than ovules How does that help the conifer reproduce?
The wind usually scatters the pollen grains of conifers. The likelihood of pollen reaching female cones is increased when there are large amounts of pollen.
Conifers produce what in cones?
Seed are produced in the cones. The female cone contains ovules which, when fertilized by pollen, become seeds.
Sticky secretion on the scales of seed cones traps?
A sticky secretion on the scales of seed cones traps pollen grains. Structure is produced by a pollen grain that lands near an ovule is pollen tubes.
How are pollen cones and seed cones are different?
Seed cones (female cones) are much larger than pollen cones (male cones).
What is difference between seed cones and pollen cones?
Pollen cones are the male pollen-producing cones, and seed cones are the female seed-producing cones in conifer trees.Seed cones are gymnosperms, which means the seeds are not enclosed within an ovary (in Greek, gymno is naked).
Does the wind often carry pollen from male cones to female cones in gymnosperms?
Yes, the wind can often carry pollen from male cones to female cones in gymnosperms.
Is there pollen cones and seed cones on the same trees?
Yes, in case of Pinus pollen producing cones (male cones) and seed producing cones (female cones) are present on the same plant. Such plants are called monoecious.
Where do gymnosperm seeds develop?
Gymnosperms do not produce spore, they produce pollen and seeds. The seeds and pollen are both produced in cones and the seed is "naked", it is not enclosed in an ovary.
What do cones do?
Male pine cones produce pollen that contains sperm cells. Female cones produce 2 seeds per scale after they are pollinated and then fertilized by the pollen grains.
Which cones produces pollen grains?
male
What type of plant produce the cones?
Conifers produce cones. The cone is like a flower. There are male cones and female cones, The male flowers open first and are usually open higher on the plant than the female cones. Wind takes the pollen where it needs to go.
How does a conifers reproduce?
The Conifer has both male and female cones on the same plant. The plant reproduces when the male cones provide pollen, and the pollen blows over to the female cones during windy days.
Where are the reproductive parts of an angiosperms located?
flowers
