Why dont the sperm nuclei of the male gametophyte of flowering plants have flagella?
During pollination, the sperm of the male gametophyte are not flagellated because they generally do not move. They rely on the growth of a pollen tube to deliver them to the egg cell.
Can you move your shoulder that move your hips move?
ummm i think you are asking, "Can you move your shoulder that move your hips?" So, yes, you could...
What is thirty four thousand in scientific notation?
Note that the term is the same as 34000.0. Then, move 4 decimal places to the left and write out: 3.4 x 104.
Why does Birling start to 'move restlessly'?
hes too fat to move
How have scientists figured out that the pacific plate is moving at about nine centimeters per year?
All of the tectonic plates move, but they move at different speeds depending on which plates are involved. The Pacific plate moves slightly more than four centimeters annually.
How does pollination take place in flowering plants?
Pollination is the process of transferring male pollen grains to the stigma of the plant (either the same plant = self-pollination, or another related plant close by = cross-pollination). The pollen grains germinate and grow down the style of the plant where the fuse with the female ovules, this results in an embryo being formed, which then becomes the seed of the plant. Pollination is aided by various (so called) "agents" or "vectors", these are things that assist in moving the pollen grains from the anther to the stigma. Vectors/ agents include: wind, insects (bees, butterflies, ants, moths etc.) water in some cases, animals (cats, dogs, sheep, cows, humans etc.)
How do you use the word anther in a sentence?
The anther is the part of a flower that produces pollen.Bees are crucial in the reproduction of many plants, as they move the pollen from the anther to another flower.
What plant structure allows pollen to move through the style?
the stigma
Which flower part are involved in pollination?
Think about the phrase, "pistol packing mama." Carpels fuse together to form the pistol which contains the style, ovary and stigma. They get pollen from the anther which is on the stamen. Bees or other pollinators move the pollen to the pistol and it travels down into the ovules and becomes seeds.
How do the sperm cells get from the stigma to the ovules?
Sperm cells move from the stigma to the ovules through a structure called the pollen tube, which grows down the style of the flower towards the ovary. This process is facilitated by the germination of pollen on the stigma, followed by the growth of the pollen tube to deliver the sperm cells to the ovules for fertilization.
Which flower part is are involved in pollination?
Think about the phrase, "pistol packing mama." Carpels fuse together to form the pistol which contains the style, ovary and stigma. They get pollen from the anther which is on the stamen. Bees or other pollinators move the pollen to the pistol and it travels down into the ovules and becomes seeds.
How to pollinate plants yourself?
For flowers i recommend that you can take the part of the animal and move the pollen into the stigma of another flower
What is the male part of the flower that produces the sperm cells?
The anther produces the sperm. It sits on top of the filament. Together these are called the stamen. To find the anther, look for the oval shaped structures that can move or wobble when touched and they most often have pollen on them.
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.
As the animals move around the flower they cause the..of pollen what do they cause?
they cause the spread of pollen to other plants, because it gets stuck in their fur and so transfered. the pollen sticks to the stigma of other plants when the animal brushes past, and fertilises the ova in other flowers of the same species.
Hat is the Reproductive structure of a calla lily?
The life cycle of a calla lily starts with a seed, which contains genetic material that, under the right conditions, including sufficient water, soil and light, will germinate and grow to form a calla lily plant. Calla lily seeds are coated seed.For a coated seed The higher weight also provides for a better and more secure ground contact and therefore provides a higher growth rate than normal seed. Coated seeds can be distinguished visually from naked seeds, because of their higher weight and different colour, the shape of the seeds does not change. A perfect flower is one that contains both male and female reproductive organs in the same flower specimen. Lilies contain both male and female parts. The male reproductive organs of a flower are known as the filament and the anther. The anther is a sac that contains the pollen of the flower. The anther is attached to a string-like structure known as the filament. Lilies contain several anther and filament combinations, known as stamens, per blossom. The female reproductive organs are typically located in the center of a lily bloom. The female organs consist of the stigma, style and ovary. All together, these pieces form the pistil. The ovary, located at the bottom of the pistil contains the egg cell. The style is the long stalk in the middle of the pistil structure. At the opposite end of the style, the stigma tops the ovary Lilies are fertilized through a process known as pollination. Pollen granules from the anther land on the stigma. The pollen then merges with the egg to complete fertilization. Generally, bees and insects help pollen move from the anther to the stigma. The pollen is extruded through the anther pores it can be spread in many ways, the most popular way for the plant to spread pollen is to attach it to the smooth hard back of many insects most commonly the beetle. The pollen is actually extruded in long very fine strands. The stigma secretes a sticky secretion that allows it to attach. After the beetle has had pollen attached to it from one plant the idea is that the beetle will use the spathe of another calla lily for shelter or for a place to trap food and by doing so they accidentally participate in an act of pollination.
How are plants involved in pollination?
Not too sure if its correct but I think its because plants are unable to move on their own in order to get the pollen grains from their anthers to the stigma of another flower for pollination, therefore the rely on external factors.
