What is difference between ungerminated pollen grain and germinated pollen grain?
Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
Why can pollen move?
Pollen can move through various mechanisms such as wind, water, animals, or self-pollination. This movement is essential for the fertilization of plants and contributes to genetic diversity within plant populations. Each method of pollen movement has evolved to maximize successful pollination in different environments.
What receives the pollen during fertilization?
During fertilization in flowering plants, the stigma of the pistil receives the pollen. The stigma is the sticky top part of the pistil, which captures and holds the pollen grains. Once the pollen lands on the stigma, it germinates and forms a pollen tube that travels down the style to reach the ovary, where fertilization occurs.
What contains pollen sacs and produces pollen that's for fertilization in the flower?
Anthers.
When a pollen grain joins with an ovam what is called?
Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.
When pollen joins with the ovum what it is called?
fertilization
Why used the mature pollen grain in pollen germination experiment?
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for fertilization
What is difference between ungerminated pollen grain and germinated pollen grain?
Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
What is fertilization of egg cells by pollen from a different plant?
Cross-Fertilization!
What the fertilization?
the seeds and embryos and pollen

Define fertilization of flowers?
fertilization is the process of producing a an offspring. in flowers the process stars when the pollen from the male sex cell/male gamete lands on the stigma the female gamete then the pollen feeds on the sticks stuff and then creates a pollen tube through the style. then the pollen fertilization the egg/ova. DEFINITION IS: fertilization is what happens when a plant is polinated
What contains pollen sacs and produces pollen that's for fertilization in the flower?
Anthers.
What is the structure that allows sperm cells to move through the style of a flower?
The structure that allows sperm cells to move through the style of a flower is the pollen tube. Pollen tubes carry the sperm cells from the pollen grains on the stigma, through the style, and into the ovary where fertilization can occur. This process is crucial for sexual reproduction in plants.
When a pollen grain joins with an ovam what is called?
Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.
When the pollen lands on an egg is this pollination or fertilisation?
When pollen lands on an egg, it is the beginning of the fertilization process. Pollination is the process of moving pollen from the male part of a flower to the female part, while fertilization occurs when the sperm from the pollen reaches and fertilizes the egg.
