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
Does all pollen germinate indiscriminately on all stigmas?
No, pollen does not germinate indiscriminately on all stigmas. Each species of plant has specific mechanisms for pollen recognition, and there are compatibility factors and biochemical signaling involved in successful germination on a stigma. Pollen that is incompatible with a stigma may fail to germinate.
What are the types of germination?
There are three main types of germination. These main types of germination are dicot, monocot, and precocious germination. Spore and pollen germination are also common for some flowers and fungi.
What is the fusion of pollen and ovule called?
The fusion of pollen and ovule is called fertilization. This process involves the union of the sperm cell from the pollen with the egg cell in the ovule, resulting in the formation of a zygote, which eventually develops into a seed.
How many chromosomes in a pollen cell?
This is an impossible question to answer the way it is phrased. One needs to know what plant species is being discussed before the question can be answered. Each species will have a unique number of chromosomes and its pollen will have half as many as the parent species.
Why germination of cms pollen is low?
The low germination of CMS (Cytoplasmic Male Sterility) pollen can be due to various reasons such as genetic factors, environmental conditions, or improper development of the pollen grains. It can also be influenced by factors like temperature, humidity, nutrient availability, and the age of the pollen grains. Additionally, disruptions in mitochondrial function or cytoplasmic genes can also contribute to low germination rates in CMS pollen.
What does pollen filter do?
pollentube helps in germination
What does a plant needs for germination?
A Stamen- to release pollen A Stigma- to receive pollen
What does a pollen tube do?
pollentube helps in germination
How might pollen germination and growth be controlled?
Pollen germination and growth can be controlled by manipulating environmental factors such as temperature, humidity, and light. Chemical treatments, such as hormones or inhibitors, can also be used to regulate pollen germination and growth. Additionally, genetic manipulation can be employed to develop transgenic plants with desired pollen germination and growth characteristics.
What happens to pollen grains immediately after pollination?
Pollen germination starts on compatible stigma
What is the job for stigma?
It allows landing of pollen grains and germination of compatible pollen grains only.
Where does germination of the pollen grain occur in flowering plants?
Germination of the pollen grain typically occurs on the stigma of the carpel (female reproductive organ) in flowering plants. The pollen grain produces a pollen tube through which the male gametes travel to fertilize the ovule.
How can pollen germination and growth be controlled?
Pollen germination and growth can be controlled through manipulating environmental factors such as temperature and humidity, as well as providing specific nutrients and growth hormones. Techniques like in vitro culture and genetic modification can also be used to control pollen germination and growth for research or breeding purposes. Additionally, using chemical inhibitors or pesticides can help regulate pollen germination and prevent unwanted fertilization in agriculture.
What is the function and parts of the stamen?
The stamen provides pollen grains and male gametes are released from pollen grains during pollen germination and fertilization
Why do plants rely on bumblebees?
because they have pollen and flowers need pollen and pollination, germination and respiration its a part of their life
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
