Introduction to Seed Plants
0 Views •
2026
Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms. Gymnosperms—cycads, ginkgo biloba, gnetophytes, and conifers—typically form cones. The pollen cones contain male gametophytes. The ovulate cones contain female gametophytes and form exposed seeds when fertilized. Angiosperms, the most diverse and ubiquitous group of land plants, form flowers, and fruit. Like the cones of gymnosperms, the flowers and fruit of...

We report an efficient and simple method to isolate embryos at early stages of development from Arabidopsis thaliana seeds. Up to 40 embryos can be isolated in 1 hr to 4 hr, depending on the downstream application. The procedure is suitable for transcriptome, DNA methylation, reporter gene expression, immunostaining and fluorescence in situ hybridization analyses.

This protocol aims to provide detailed procedures for collecting, fixing, and maintaining mycoheterotrophic plant samples, applying different microscopy techniques such as scanning and transmission electron microscopy, light, confocal, and fluorescence microscopy to study fungal colonization in plants tissues and seeds germinated with mycorrhizal fungi.
FAQs
Water uptake allows the seed to absorb moisture and resume biological activity. This process activates metabolic enzymes that support the embryo’s growth, while adequate oxygen enables the ongoing cellular processes needed for development. If these conditions are suitable, the radicle can emerge first, marking the transition from a dormant seed to a developing seedling.
Temperature influences whether germination-related metabolic activity can proceed, while light conditions matter for many species. Planting depth also affects the seed’s access to moisture, oxygen, and light. Depth that is unsuitable for a particular seed can therefore reduce germination success or interfere with the emergence and early development of the shoot.
Radicle emergence is an early visible sign that the embryo has resumed growth. The radicle, which becomes the embryonic root, generally appears before the shoot and establishes the first phase of seedling development. Observing this sequence helps biologists examine germination timing, early plant life-cycle stages, and responses to environmental conditions.
Begin with viable seeds and place them in a suitable growing medium at an appropriate depth and spacing. Provide adequate moisture, oxygen, and temperature, while considering whether the species requires particular light conditions. Continued observation can reveal whether germination occurs and whether the emerging radicle and shoot develop into established seedlings.
Planting depth and spacing shape the conditions surrounding each seed and emerging seedling. Appropriate depth supports access to the moisture, oxygen, temperature, and light conditions required by the species, while suitable spacing supports establishment and later development. Researchers and growers adjust these variables when evaluating germination success or encouraging uniform plant growth.
Seed planting supports several biological and practical objectives, including studying plant life cycles, propagating plants, producing crops, and restoring habitats. In research, it provides a way to examine how environmental conditions affect germination and establishment. In ecological restoration, the resulting seedlings can contribute to recovery of plant communities in suitable habitats.
