When a dry seed makes touch with moist soil or growth medium, it begins to absorb water via its seed coat. As the seed absorbs more water, it swells and the seed coat splits open. The embryo within the seed consists of a little stalk and root. The first structure to develop from the seed is the root.
- It attaches the plant to the soil as it grows and begins to absorb water through the root.
- After the root absorbs water, the seedling shoot begins to develop.
- The majority of the vegetable plants we cultivate are “dicots.” Dicots have two seed leaves that arise from the sprouting seed on the shoot.
- Dicots include tomatoes, peppers, cabbage, beets, lettuce, beans, cucumbers, and squash.
A few vegetables, including sweet corn, onions, and asparagus, are monocots. Monocots have a single seed leaf on their young shoots. Once the branch emerges from the soil or growth medium with its one or two seed leaves, we refer to the plant as a seedling.
What causes germination?
The seeds stay inactive or latent until the conditions are optimal for germination. All seeds need water, oxygen, and suitable temperature in order to germinate. Some seeds also require enough lighting. Some germinate more well in broad light, while others require darkness.
When a seed is exposed to the correct circumstances, the seed coat absorbs water and oxygen. The cells of the embryo begin to expand. The seed coat then splits apart, and a root or radicle develops, followed by a shoot or plumule containing the leaves and stem. Numerous factors can inhibit germination.
Overwatering deprives the plant of sufficient oxygen. When seeds are planted too deeply, their stored energy is depleted before they reach the soil surface. Dry circumstances indicate that the plant lacks sufficient moisture to initiate and sustain germination.
- Some seed coats are so impermeable to water and oxygen that the seed cannot germinate until the seed coat breaks down.
- Soaking or rubbing the seeds will assist in removing the seed covering.
- Examples include morning glories and locust seeds.
- Other seeds require exposure to the correct temperatures.
- Apple seeds will not germinate unless they are chilled for an extended length of time.

How does a seed grow into a flower?
Procreation – The wind or a pollinator, such as a honeybee or moth, transport pollen from the stamens to the pistil. When a pollen grain settles on the pistil’s tip, it releases sperm that move down within the pistil to fertilize the ovary at the pistil’s base.
- After pollination and fertilization, the ovary begins to produce seeds.
- In the meantime, the flower wilts as the ovary grows and the seeds within it mature until they are ready to be dispersed.
- With annuals, the plant dies after producing mature seeds.
- Once the mature seeds are dispersed by perennials, the plant stores nourishment in its roots for use the following year, and then enters dormancy until environmental factors start a fresh cycle of growth, blooming, and seeding.

Plant Life Cycles – As living organisms, plants develop and reproduce as do all other living things. They follow a cyclical pattern of beginning a new life, expanding, and then returning to the beginning (reproducing). There are five phases in the life cycle of a plant.
