What else can I help you with?
Pollination can be best described as?
the transfer of the male pollen grain to the female organ.
What does a pollen grain look like?
The pollen for each kind of tree or flower is distinctive to that species, so there is no definite description for what pollen in general looks like - the grains aren't even all round; the size also varies: for instance, a grain of pollen from an elm tree (which is round) is about 20 micrometers in diameter, whereas a pollen grain from a Scots pine tree is kinda kidney shaped, & measures about 40 x 60 micrometers
Describe how Mendel cross pollinated pea plants?
Gregor Mendel cross-pollinated pea plants by manually transferring pollen from the stamen of one pea plant to the pistil of another pea plant. He carefully removed the anthers from the first plant to prevent self-pollination and then applied the pollen to the stigma of the second plant. This process allowed Mendel to control the genetic makeup of the offspring and study the inheritance patterns of specific traits in pea plants.
Name the 2 things which join to make a seed?
There are two things that must join to make a seed. The zygote, or embryo, must join with the ovule.
What are the five steps of pollination?
Step 1: A grain of pollen falls onto stigma. Step 2: animal enters flowers and brushes against anther and then is coated in pollen. Step 3: Some pollen can fall onto stigma as animal leaves flower Step 4: pollen falls onto the stigma of the next flower. Step 5: a small seed forms in the ovary in the plant. This then starts the process all over again
Does pollination occur before fertilisation?
Yes, pollination is the process of transferring pollen grains from the male reproductive organs of a flower to the female reproductive organs. Fertilization occurs after pollination, when a pollen grain meets the ovule of a flower and forms a seed.
How do you think pollen grain reach pistil?
The pollen grain reach the pistil either by self-pollination or by cross pollination by pollinators.
What do we call a joining of a pollen grain with an ovule?
Of course, it's called 'Pollination'
What do we call the joining of the pollen grain with the ovule?
Pollination.
Is pollination in animals a form of asexual reproduction?
Pollination only occurs in flowering plants. It is part of the process of sexual reproduction. The pollen grain contains the male gamete.
How does a pollen grain get to the stigma of a pistil?
It could be done by animal pollination , wind pollination or even self pollination.
What happens between pollination and fertilisation?
After pollination, the pollen grain germinates and forms a pollen tube that grows down the style of the pistil to reach the ovule. Fertilisation occurs when the sperm cell from the pollen grain fuses with the egg cell in the ovule, resulting in the formation of a zygote.
What is the part of the flower that receives the pollen grain from the anther?
The stigma recieves the pollen grain from the anther. It then travels down the pollen tube inside the style and goes to the ovary.
What do you call the transfer of pollen from one plant to another?
The transfer of pollen from one plant to another is called pollination. It is a crucial step in the reproduction of flowering plants as it enables fertilization and seed production. There are different methods of pollination, including wind, insects, birds, and other animals.
What name is given to the fertilization of plants by animals?
When a pollen grain comes into contact with the stigma, or top of the pistil, it sends a pollen tube down into the ovary at the pistil's base. Fertilization of plants by animals is called pollination.
What is the male sex cell from a pollen grain called?
The male sex cell from a pollen grain is called a sperm cell. It is responsible for fertilizing the female sex cell (ovule) in plants during the process of pollination.
What is needed for pollination to take place?
In order for pollination to occur, what must happen to the pollen grains is that they have to be transferred to the stigma in a flower of the same species. The stigma is the female part of the flower.
