What else can I help you with?
What structure are you likely able to see in the pollen tube and when would you be able to see it?
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
What features of a pollen grain makes it suited for being brushed off an insect?
A pollen grain's surface is often rough and sticky, allowing it to adhere to an insect's body as it moves from flower to flower. Additionally, the shape and size of pollen grains match well with insect hairs, making them easy to brush off as the insect travels. Lastly, the lightweight nature of pollen grains makes them easily dispersed by the movement of insects.
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.)
What is the process by which organisms change over time called?
The process by which organisms change over time is called evolution. This process involves genetic changes in populations that lead to differences in traits among individuals, with some traits being favored based on their impact on survival and reproduction.
How is pollen cell adaped for its function?
Pollen cells are adapted for their function of reproduction in plants by being lightweight and easily dispersible through the air or by animals. They have a tough outer coating to protect the genetic material inside. This allows pollen to reach female reproductive structures and facilitate the fertilization process.
What is the process that had taken place resulting in the stigma being covered with pollen grains?
Pollination
What is the process of a liquid being boiled into a gas?
This process is called vaporization.
What structure are you likely able to see in the pollen tube and when would you be able to see it?
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
The process of being alive is called..?
living
What is that process called when a fraction is being multiplied by a variable?
It is called multiplication!
What is the process of excess water being evaporated from plants?
This process is called transpiration.
What is a solid becoming a liquid?
The process ofa liquid being converted into a solid is called freezing.
What is the structure that develops into a pollen grain?
First pollen falls from a male cone onto a female cone. In time a sperm cell and an egg cell join together in an ovule on the female cone
The process of solid materials being shaped and reformed due to heat of pressure is called?
The process of solid materials being shaped and reformed due to heat or pressure is called
What is a process of reasoning called?
being married too long
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
What is the process of light being sent back from an object called?
reflection
