What produces pollen grains?
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
Pollen is produced by what type of cones?
Pollen is produced by male cones, also known as strobili, in gymnosperms, such as conifers and cycads. These cones shed pollen grains that contain male gametes for fertilizing the ovules in female cones.
What are the reproductive structures of genosperms?
Most Gymnosperms are diecious with the male and female reproductive organs on different plants. The male "flower" produces pollen and the female "flower" contains the ovary. Many female gymnosperms produce cones that house the fertilized eggs until the seeds are mature.
What is a male cone?
A male cone is a reproductive structure found in gymnosperms, such as pine trees. It produces pollen grains that are spread by the wind to fertilize female cones, resulting in seed production. In comparison to female cones, male cones are usually smaller and produce pollen.
in which part of a pine pollen grain produced?
Pine pollen grains are produced in the male cones of pine trees. These cones undergo a process called microsporogenesis, where microspores develop into pollen grains. The pollen grains contain the male gametes necessary for fertilization and are released into the air during the pollination season.
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.
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.
Which is the reproductive event in conifers where pollen grains from male cones are transferred to female cones called?
pollination
What do male cones produce?
Male cones produce many pollen grains to enhance its reproductive rate & hence its evolutionary success
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.
What is the flower part that produces and stores pollen grains?
The flower part that produces and stores pollen grains is called the anther. It is the swollen tip of the stamen, which is the male reproductive organ of a flower. The anther contains pollen sacs where pollen grains are developed and stored until they are released for pollination.
What develops on the male cone?
the zygote Edited answer: Pollen grains develop on the male cone.
