How do seedless plants reproduce?. How do seed plants reproduce?. How can you identify fruits?. ACTIVITY. Chapter 8 Section 3. What is a Seed Plant?. Seed plants outnumber seedless plants. Produce much of the oxygen we breathe. All seed plants have roots, stems, and leaves. The plants that you see are the sporophytes, the gametophytes are microscopic. Seed Plants. Recall that seedless plants were either nonvascular or vascular… either way they did . NOT. produce seeds. Seeds can be found . everywhere. …acorns, dandelion seeds, kernels of corn, even peanuts!.
