They evolved after the seedless vascular plants.
Explanation:
- The gymnosperms were the first seed plants to have evolved some about 382.7 million to 358.9 million years ago in the Devonian period.
- They were the ancestor of the seed plants like the heterosporous, earlier gymnosperms were pteridosperms or seed ferns. The vascular plant's particular ferns consist of tissues that don't make flowers or seeds but have unicellular pores.
Answer:
The answer of part A is asexual reproduction and the answer is part B is meiosis.
Explanation:
A kind of reproduction by which emergence of offspring takes place from a solitary parent, and receive the genes of that parent only is known as asexual reproduction. In the process, the combination of gametes does not take place, and at the same time the chromosomes number almost never changes, that is, it remains the same.
Gametes are produced by a kind of cell division known as meiosis. This two-step division procedure generates four daughter cells, which are haploid. The haploid cells comprise only one set of chromosomes. When the fusion of male and female gamete takes place the process is known as fertilization, which further gives rise to a zygote.
