Question

Are megaspores haploid or diploid? What process do megaspores undergo to form the egg or ovule? Is the tissue surrounding the egg haploid or diploid? Once the egg is fertilized what structure will form? Are pine seeds haploid or diploid? How are pine seeds be dispersed through the environment? What cell division process do pine seeds undergo to create a new pine tree? Angiosperms Collectively, the male flower parts are called the Collectively, the female flower parts are called the Use the table below to describe the function of each flower part and if it is male, female, or neither.

Explanation / Answer

1) Megaspores are gametes which are haploid produced by megaspores mother cells by meosis division.

2) megasporoporogenesis is the process which produces Megaspores to form egg or ovule.

3) the tissue surrounding the egg is diploid in nature inside it undergoes mitosis division to form egg cells or ova cells.

4 ) after egg is fetilized with sperm it produces zygote, which I'd diploid in nature.

5) Pine seeds are diploid in nature.

6)pine seeds have wing like structures which dispersed by the wind.

7) Pine seeds undergoes mitosis division and produces into whole tree as diploid vegetative structures.

8)male flowers are called androecium , contains stamens, anthers, pollen.

Female flowers is called gynoecium contains stigma, style and ovary parts and ova cells.

Anther, filaments is male called stamens.

Pistal, style, stigma is female.

Sepals, petals are neither, these are vegetative parts
