How do pollen tubes grow?
In angiosperms the pollen tube germinates from the pollen grain and grows the entire length through the Stigma_(botany), Style_(botany), Ovary_(botany) and Ovulesto reach the eggs. In Maize, this single cell can grow longer than 12 inches to traverse the length of the pistil. The sperm cells by themselves are not motile and are carried within the tube. As the tip of the tube reaches a synergid, it bursts and releases two sperm cells leading to a double fertilization. One sperm unites with the egg cell to produce the embryo of a new plant, while a second sperm unites with the central cell(polar nuclei) to produce the Endospermof the seed. The endosperm is rich in starch, proteins and oils and is a major source of human food (e.g., wheat, barley, rye, oats, corn)
A process in which cells can copy themselves?
Mitosis for normal cells, meiosis to make gametes (eggs, sperm, pollen)
How does fertilisation occur in flowers?
Have you ever wondered what are all those bees and hummingbirds looking for inside the flowers. Well it is a sweet substance that the plant provides for them called nectar. The nectar is advertized by the petals. When the animal goes for the nectar, the flower passes on the pollen to it. That is why if you look carefully you´ll see a yellow dust all over them. That is the pollen. Since they will need to get more nectar, the animals go searching for another flower and during that process they transfer the pollen from flower to flower. The pollen is collected by the flower´s stigma and flows down the style and into the ovary were it will fertilize the ovule. Amazing!
What would happen to human sperm inside a female dog Does it die immediately or does the sperm try to mate with the females eggs?
The sperm is incompatible with the female eggs, and would not interact with it.
When pollen hooks up with eggs in the same flower then it makes a?
dsd
Where sperm cell are found?
sperm cells are found in the soil to fertilize the eggs
What iz pollen?
Pollen is the reproductive gametes for plants (similar to eggs and sperm for humans), when pollen comes into contact with the stigma of a plant, the reproduction process for the plant begins

What are the first stages of fertilization?
Eggs released sperm attacks the egg egg and sperm are now together then your egg is fertilized !!
Suggest one use of a stigma to a flowering plant?
A Stigma can help in collecting/catching the pollen (sperm) of another plant, and holds the eggs to be fertilized by the pollen.
What is it called when the sperm from one plant fertilized the eggs of the same plant?
Plants do not have sperm. The male gamete is found in the pollen grain. The egg is usually called an ovule. When the pollen from the same plant is used, we speak of self pollination, and when the gametes fuse it is self fertilization.

What is a external fertalisation?
External fertilization occurs when the egg is fertilized by the sperm outside of the female's body. As when a female fish deposits her eggs on the ground and the male fish ejaculates his sperm over the eggs. Internal fertilisation occurs when the sperm fertilizes the egg inside the female's body. Which is what mammals do, including human beings.
How does a coral fertilise its eggs?
During spawning the coral releases both eggs and sperm into the water at the same time. Fertilization occurs in the water.
When does your body undergo meiosis?
Only sex cells such as sperm and eggs undergo meiosis. This occurs at puberty.
A process in which cells can copy themselves?
Mitosis for normal cells, meiosis to make gametes (eggs, sperm, pollen)
