Answer:

Neogene period is almost 31% of Cenozoic area.

Explanation:

Cenozoic era exists between 66 mya and zero mya. However, Neogene period existed between 23 mya to 2.6 mya. The difference is 20.4 mya.

To calculate the percent of neogene,

= (20.4/66) x 100

= 30.9%

Therefore, Neogene was approximately 31% of total Cenozoic era.

<u>(B) ability to produce the most cells during </u><u>mitotic growth</u><u> of the pollen tube.</u>

  • In seed flora, the female reproductive organ consists of the ovule. it's far in which female reproductive cells are produced and housed. After fertilization, those cells sooner or later become a seed, which then ripens to form a complete-grown adult plant. Ovules are housed in ovaries at the base of a vase-like shape referred to as a carpel, which has an opening on the pinnacle referred to as a stigma and a neck known as a style.
  • Following fertilization, the ovule starts offevolved to swell and its wall begins to thicken so that you can transform right into a seed, while the ovary begins to make bigger round it and change into the fruit. take into account that even as some plants, just like the kiwifruit, have many ovules that grow to be numerous seeds in the fruit, different flora, just like the avocado, handiest have one ovule in their ovary.
  • The place of the ovules is any other manner that plants differ from one another in regard to them. Ovules are particularly discovered on the scales of lady cones in gymnosperms, consisting of conifers, whereas they're discovered in the ovary inside the carpel in angiosperms, or flowering vegetation.
