Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

Explanation:
That's the main difference between mushrooms and truffles.
This isn't always the case and there is no reason it should be .Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive. Let's take eye color as an example.
Answer:
Los plasmodesmos forman una ruta importante para la comunicación entre las células vegetales. Regulan la comunicación de célula a célula, permitiendo así la diferenciación de órganos y tejidos vegetales.
Los plasmodesmos facilitan el movimiento de moléculas entre las células, desde pequeños productos fotosintéticos hasta grandes proteínas y ARNm. En el tejido vascular, los plasmodesmos son cruciales para el movimiento de nutrientes. También son cruciales durante el desarrollo porque, a diferencia de las células animales, las células vegetales no se mueven. Por tanto, la expresión correcta de genes tanto temporal como espacialmente es importante. Mientras que las células vegetales, como las células animales, son capaces de interactuar receptor-ligando para enviar señales a otras células, los plasmodesmos ofrecen contacto directo. Además, el tamaño de la manga difiere en diferentes tipos de células y tejidos vegetales. Por tanto, los plasmodesmos son un componente celular activo en el transporte intercelular, durante el desarrollo y en el tejido maduro.
