Question

in which structures would reproduction occur in some non - flowering land plants?
cones
leaves
roots
stems

Explanation:

Non - flowering land plants like conifers (gymnosperms) reproduce using cones. Cones are the reproductive structures in these plants. Male cones produce pollen (male gametophytes) and female cones contain ovules (which develop into seeds after fertilization). Leaves are mainly for photosynthesis, roots for anchorage and absorption of water and minerals, and stems for support and transport of substances.

Answer:

cones
