Seeds offer the embryo protection, nourishment, and a mechanism to maintain dormancy for tens or even thousands of years, ensuring that germination can occur when growth conditions are optimal. Plants can be dispersed through both natural and man-made means with the help of seeds. Seed dispersal is the process by which seeds are transported from one location to another, usually by wind or water.
In the case of seeds, this is accomplished by the movement of the seeds through the air, which is why they are often referred to as “airborne” seeds. However, seeds can also be transported by other means, such as the wind, water, or animals. For example, a seed can be carried by a bird or a mammal, as well as by insects and other animals that are attracted to the scent of a particular plant or animal. These animals are known as pollinators.

Why are seeds in advantage for seed plants?
The seeds protect the embryo from harsh environmental conditions. They provide sustenance to the embryo. Seeds are also important for pollination. Pollination is the transfer of pollen from one plant to another.
What are 3 advantages to seeds?
Seeds offer the following advantages to angiosperms: <br> i) They provide nourishment and parental care to the developing embryo, <br> ii) They protect the embryo from harsh environmental conditions. <br> iii) The seeds can be stored for long periods of time without the need for refrigeration.
Seeds can also be used as a food source for insects, birds, reptiles, amphibians, fish, and other invertebrates. Seeds are also used in the manufacture of fertilizers, pesticides, herbicides, insecticides and insect repellents.
What is an evolutionary advantage of seed dormancy?
Dormancy enables seeds to avoid germination during periods that are only ephemerally favorable. Plants can distribute their offspring across time and bet-hedge against unpredictably variable environments by having seeds with different degrees of dormancy. The ability of a seed to survive in an environment that is not optimal for its survival is a key feature of the seed dispersal process.
In the case of seeds, the ability to disperse is dependent on several factors, including: (1) the environment in which the seeds germinate; (2) how long it takes for the weather to change; and (3) whether or not the climate is conducive to the growth of seedlings (e.g., temperature, humidity, light, etc.).
For example, some seeds are more likely to be dispersed than others, depending on the type of environment they are found in. The most important of these factors is the presence or absence of predators, such as insects, birds, and other animals. Other factors include the amount of light available to seeds during the growing season, as well as the availability of water and nutrients.
Why are seed plants an evolutionary advantage quizlet?
Why are seed plants an evolutionary advantage? Seeds protect and nourish young, growing plants. Orchids have a novel feature called seed dispersal, which allows them to spread seeds from one plant to another. Orchid seeds are small, about the size of a grain of rice, and they can be carried by wind, rain, or water.
They can also be picked up from the ground or dropped from a height of up to 30 feet (9 meters). Orchid seedlings can survive for several years in the wild without water or food, but they will die if they do not receive enough water and nutrients to survive.
The seeds of the orchid plant are very nutritious containing high levels of vitamins A – (See list below)
- As well as minerals such as calcium
- Iron
- Magnesium
- Phosphorus
- Potassium
- Zinc
- Copper
- Manganese
- Chromium
- C
- K
- Selenium
- Thiamine (vitamin b1)
They are also rich in essential fatty acids, vitamins B6, B12, folate, pantothenic acid, riboflavin, niacin and pyridoxine, all of which are essential for good health.
Why do seed plants have an advantage over seedless plants?
Plants with seeds have advantages over plants without seeds. The young plant uses the food stored in the seed when it begins to grow. The seeds of seedless plants don’t have food to help them grow. It is possible to spread seeds from one plant to another. Seeds can also be stored for long periods of time.
Seeds are made up of DNA, which is the genetic material that makes up all living things. Plants, on the other hand, are composed of many different kinds of cells, each of which has its own DNA. These cells are called leaves, stems, roots, flowers, fruits, seeds, and so on.
Each type of cell has a unique set of genes that make it unique from all other cells in its type. This means that plants and seeds are very different from each other, even though they are both made of the same basic material.
Why seeds are more advanced than spores?
Because of how they sustain plant life, seeds are considered to be more advanced than spores. The inner workings of a seed reveal a multicellular environment that is capable of nurturing the plant and preparing it for the next stage of growth and development. Seed germination is the process by which the seed germinates into a new plant.
It is a complex process that involves a variety of factors, including temperature, humidity, light, nutrients, water, and the presence or absence of other organisms. The process is also dependent on the type of seed that is being used, as well as the environment in which it is grown.
For example, if a plant is growing in a hot, dry environment, it may not be able to grow as fast as it would if it were growing under a cooler, wetter, more humid environment. Seeds can also be affected by other factors that affect the growth of plants.
What adaptation makes seed plants suitable for land?
The presence of a broad root system for anchorage and absorption, as well as the development of mechanical tissues for support and vascular tissue for long-distance transfer of sap and food, are all characteristics of seed-bearing plants. Seedlings are immature plants that have not yet developed all of their leaves and flowers.
Adult plants, on the other hand, have fully developed leaves, flowers, and stems and are capable of producing seeds. The difference is that seedlings do not have the ability to take in water and nutrients from the soil, while adult plants do. It is important to note that the presence or absence of seeds does not necessarily indicate the age of the plant.
In fact, it is not uncommon for plants to be in the process of germination for as little as one day.
