Answer 1

Explanation:

Mosses and ferns reproduce by spore formation.

Spirueggera species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.

Fungi reproduce asexually by fragmentation, budding, or producing spores.The most common mode of asexual reproduction is through the formation of asexual spores, which are produced by one parent only (through mitosis) and are genetically identical to that parent.

The most common mode of vegetative growth in yeast is asexual reproduction by budding, where a small bud (also known as a bleb or daughter cell) is formed on the parent cell. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell.

Hydra reproduce asexually by budding. The buds form from the body wall, grow into miniature adults and break away when mature. When a hydra is well fed, a new bud can form every two days.

In Bryophylum, reproduction occurs through asexual means, specifically, through vegetative propagation of leaves. The leaves of Bryophylum are broad possessing notches at its margins, these are the locations from which buds(notches) arise.

Rose culture occurs via four methods: seed, cuttings, layering and grafting. Seeding is the only means of propagation through sexualreproduction and allows more genetic diversity. Asexual reproduction via the other methods produces plants that are true to the parents

Potatoes are mainly propagated by vegetative methods (cloning). Potato tubers have nodes or eyes from which the new growth begins. The new stems growing from each eye are called sprouts which giver rise to the new plant. Vegetative seed can be either a whole tuber or a cut tuber.
