Generally, seeds are used for reproduction and belong to sexual reproduction.

apple tree

The natural state is that seed reproduction belongs to sexual reproduction.

However, in the process of artificial fruit tree cultivation, grafting propagation is generally used, which belongs to asexual propagation (vegetative propagation)

carrot

Generally, seeds are used for reproduction and belong to sexual reproduction.

In the section of "Cell Engineering" in high school textbooks, carrot plants are obtained by tissue culture with carrot root cells, which belongs to asexual propagation (vegetative propagation).

Chinese yam

The first kind: yam is a seed reproduction, not a sexual reproduction.

The second species: "yam bean" is planted between the axils of yam leaves. After the stems and leaves withered in autumn and winter, "yam bean" fell to the ground and germinated in the following spring, which is asexual reproduction (vegetative reproduction).

Chinese rose

In the natural state, offspring from seeds are sexual reproduction.

When artificially cultivating new varieties, different varieties of Chinese rose are planted together, cross-breeding is carried out, and offspring are propagated through seeds, which is sexual reproduction.

Artificial planting, cutting propagation, branching propagation, layering propagation, grafting propagation, etc. Most of them are used, that is, asexual reproduction (vegetative reproduction).
