Triploid endosperm nucleus is a result of?
Triploid endosperm nucleus is a result of double fertilization in angiosperms, where one sperm fertilizes the egg cell to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. The endosperm serves as a nutrient source for the developing embryo.
Why do endosperm formation does not occur until fertilization take place?
Endosperm formation is triggered by fertilization because it involves the fusion of the two sperm cells with different nuclei in the embryo sac, leading to the triploid (3n) condition necessary for endosperm development. Without fertilization, the endosperm would not receive the necessary genetic contribution to develop properly and support the growing embryo.
What is the starchy food that feeds a developing seed?
The starchy food that feeds a developing seed is endosperm. Endosperm is a tissue found in seeds that provides nutrients to the developing embryo, enabling it to grow and develop into a new plant.
What is the reaction of iodine on the endosperm of a maize seed?
Iodine reacts with starch to form a blue-black color. In maize seeds, the endosperm contains starch, so when treated with iodine, the endosperm will turn blue-black if starch is present. This reaction is commonly used to test for the presence of starch in plant tissues.
What are the three parts of a seed and what is the purpose of each part?
Seed coat, micropyle, endosperm and embryo are major parts of a seed. The seed coat protects, micropyle allows water to move in, endosperm nourishes the embryo and on germination a new plant emerges from the embryo.
What is a xenognosin?
A xenognosin is an organic compound which stimulates the formation of a haustorium.
Name an example of a seed that has liquid endosperm?
An example of a seed that has liquid endosperm would be a coconut. While it does contain cellular endosperm, the coconut milk would be considered liquid endosperm.
Once fertilized the central cell becomes?
the endosperm
What is a food-rich tissue that nourishes the seedling as it grows called?
endosperm
What do the result of the iodine test indicate about the composition of the endosperm?
The result of the iodine test indicates the presence of starch in the endosperm. When the endosperm is stained blue-black by iodine, it suggests a high starch content. Conversely, if there is little to no staining, it indicates a low starch content in the endosperm.
Is there is endosperm present in gymnosperm?
No, triploid endosperm is in angiosperms only. Gymnosperm means "Naked Seed."
What is the 3n nutritive tissue in the seed of angiosperms called?
the triploid The endosperm is a nutritive tissue which nourishes the developing embryo. The endosperm in angiosperm is triploid (3n) and it is a post - fertilization structure.
What are the uses of the endosperm portion of the wheat kernel?
White flour is made only with the endosperm portion of the wheat kernel. Farina is also made from the endosperm, but it is ground to produce a granular product.
What part of the grain that remains after being refined?
The part of the grain that remains after being refined is the endosperm.
What feeds the plant embryo?
The plant embryo is nourished by the endosperm, which is a tissue rich in nutrients that surrounds and supports the embryo during seed development. The endosperm provides essential carbohydrates, proteins, and lipids for the growing embryo until it can establish its own root system and begin photosynthesis.
Seedling is nourished by what?
the endosperm
What is ploidy of the endosperm?
3n
