Seed plants are spermatophytes, and they are also known as phaenogams or phanerogams. They are called seed plants because they can produce seeds. Seed plants are most times described as a subgroup of vascular plants. Although they are vascular plants, they differ from other vascular plants. In seed plants, there are three important organs. The three organs are leaves, roots, and stems.
Leaves are what developed into flowers, and some parts of the flower are modified to produce the fruit. Inside this fruit, there could be more than seeds. The various importance of seed plants in human life can never be overemphasized.
Human beings depend greatly on seed plants, especially for most of our nutritional needs. Aside from the fact that we get most of our nutritional needs from seed plants, they are also important sources of materials used in making medicine. Manufacturers of most drugs today use different kinds of seed plants for this purpose.
One of the things that you should know about seed plants is that they are obviously a group of plants that would bear seeds. There are gymnosperms and angiosperms that are part of the group. The seed plants will come with three different parts namely the embryo, the supply of nutrients that would need to go to the embryo, and the seed coat.
There are some people who call seed plants by their other names. They are sometimes called spermatophytes. Others would call them phanerogams. Take note that angiosperms are known to cause flowers while gymnosperms will not be able to produce flowers.
There are many statements about seed plants that are true because there are many facts and characteristics that make up seed plants. One statement true about seed plants is that they are only produced by angiosperms, which are flowering plants.
Another fact about seed plants is in regards to the sporophyte generation. This generation tends to be more reduced than the ferns that are in seed plants. Along with that, the sporophytes are independent of gametophytes.
The seeds in these flowering plants will grow in the ovary, which is the female reproductive system of the plant. The seeds then ripen into a fruit.
Seed plant are defined as a group of plants. The group is comprised of angiosperms and Gymnosperms. The seeds from these groups have three parts. The first part of the seed plant is the embryo. Then, there is the nutrient supply that is for the embryo.
Lastly, there is the seed coat. Seed plants can be found in every environment. Angiosperms are known as the flowering plants. This is a large group and it has many different and widely known plants that are in many different habitats. One of the oldest seed plants that were first discovered were the fossil seed ferns
True to seed, or growing true, refers to plants whose seed will yield same type of plant as the original plant. Open-pollinated plants, which include inheritances, will typically grow true to seed if another type does not cross-pollinate them.
For example, saving a specific type of tomato should result in another tomato plant. If cross-pollination occurs, the resulting seed will be natural hybrid, and many have some features of each parent or could look different than either.
If a specific type of tomato plant cross-pollinates, you will see a new and more complex plant grow as a result. Many of these seeds commonly sold are called intentional hybrids, crosses made between two different plants for a certain benefit, such as disease resistance or improved flavor. These seeds will never grow true.
