siemenkasveissa
Siemenkasvit, also known as Spermatophytes, represent a major division of the plant kingdom characterized by the production of seeds. This is their defining feature, distinguishing them from seedless vascular plants like ferns and mosses. Seeds are crucial for reproduction, as they contain an embryo, a stored food supply, and a protective outer coat. This structure allows for dispersal and survival in various environmental conditions.
The life cycle of seed plants involves alternation of generations, with a dominant sporophyte stage. Within
Siemenkasvit are further divided into two major groups: gymnosperms and angiosperms. Gymnosperms, meaning "naked seeds," produce
