Why doesn't a potato plant grow from the seeds?
534940
Potato can and does grow from seeds.\n\nCommercially cultivated potato for market is grown from the 'eyes' or 'bud' because of the following reasons...\n\n1) It is a much quicker method to cultivate.\n\n2) The quality is constant and as expected, it does not change.\n\nIn the experimental institutions , on the other hand, potato is grown from the seeds . Hybrids are created to bring the desired qualities of two different potatoes together and their seeds are collected to be given to the farmers.\n\nIn short, all the methods are adopted depending upon the need of the hour.

Plants which reproduce without seeds appeared first in the history of the Earth.  Plants with seeds appeared much later.

Commercial processing of seeds is designed to ensure maximal germination, not to stop them germinating.\n\n\nThe simple fact is that not all seeds are viable, just as not all pregnacies result in children.\n\n\nFor various reasons seeds can fail. Sometimes that is because of genetic flaws within the seeds. Sometimes the seeds get infected with diseases or mites that eat them before they germinate.\n\n\nMostly seeds fail simply because theye weren't treated right. Sometimes the seeds are too old and have died. Sometimes they are buried too deep, or have been watered too much, or not watered enough, or let get to hot, or too cold or a million other environmental factors that prevent germination.

there are tons of factors affecting plant growth. one of them is the kind of soil for the plant to grow. some plants need a specific type of soil in order to grow properly. another factor is the sunlight and food it gets. it needs the propwer nourishment for the palnt to fluorish. next is the nutrients that a plant need. some may need medicines to help them grow better.

One of the main challenges was reproducing with out the water. This was eventually made possible with spores. However the spoors still needed to be close to the water other wise they would die. Seeds came around later and solved the problem. The seeds provide the nutrients that the plant needs untill it can support itself.

so it can produce fruit, therefore seeds, and multiply. Without fertilisation a plant cannot do that, and would die out.

To answer this question one must get to the 'root' of the problem. We could 'branch' off in any direction from there and ascertain why they refuse to 'leaf' it be. Could it be that at the 'core' level, there are 'seeds' of discension? Or is it on a more 'cellular' level. It presents a strange 'dicot'omy at best.

B...ferns do not produce seeds, they produce spores so E cannot be it.

Some plants are notorious self seeders.  Their seeds drop very easily and grow even easier.  Others depend on insects and birds to pick up their seeds and spread them.

Several reasons.\n\n1) Our crop plants have been bred for the traits of being tasty and having large amounts of energy rich material in their bodies. The wild ancestors of our food crops were almost all much smaller plants and contained large amounts poisons to discourage animals from eating them. We bred them to be larger and to have no toxins so that we could eat them easily. That also makes it easy for insect pests to eat them. However things like carrotweed and onionweed for example still retain the properties of the wild forms of carrots and onions and they are very good (or bad) weeds.\n\n2) Wild plants, even weeds, don't grow in large concentrations. You might only get a patch of wild plants a few metres across, or else the plants will be scattered with only one growing every few metres. That dispersal makes it much harder for insects to find wild plants they want to eat. We plant our crops in high density and high concentration which attracts the attention of insect pests and makes them all the more damaging.\n\n3) We alter the environment of our crop plants by keeping them watered and fertilised, removing competing plants etc. That makes garden beds an ideal growing habitat for ALL plants. In contrast the shady, compacted, dry deficient environments of th natural world will only support a limited number of plant species. What that means is that there are potentially millions of species that will grow in a garden bed if they can get their seeds there. IN contrast very few species will grow in any wild habitat. Simple probability means that we are going to have more weeds in a garden bed.\n\n4) The same act of preparing favourable growing beds for crops means that the crops are healthy and lush. That makes them prime targets for insects.\n\n5) Many food and flower species are also weeds. Olive trees for example are serious weeds in Australia and blackberries are a serious weed in New Zealand. Even more flower species have become weeds. Lantana and tea tree, grown originally for their flowers, have become a serious weeds in Hawaii and Florida respectively. So it's simply not true to say that the plants we want to grow require a lot of care. Many thousands of plants that people wanted to grow have become weeds around the world.

This is a chicken-or-egg question....but not all plants make seeds...so the fact is that some plants reproduce by other means..aka no seed was needed, even at the beginning.\n \nDepending on your beliefs:\n\n1. All plants were instantly created as they are now. Seeded plants from seeds or "original" plants, and non-seeding plants from "orginal plants". Just created and unchanging.\n\n2. A few types of master plants families were created and subsequent diversification created sub types. Created, then evolved.\n\n3. Plants come from ancient photosynthetic ancestors and continue to develop today. Prior to the Cretacious period, no plants were flowering, and thus there were no seeds. Classic evolution scenario.\n\nContrary to popular opinion, evolution and creationism don't inherently contradict each other - all life could have been designed to come from proto-organisms into the great variety of life we have today, or diversity has been there all along, but ongoing evolution allows for environmental adaption. One does not prevent/prove/deny the existence of the other.\n\nIf life did not have any abiltity to adapt, it would quickly die. If all plants died from freezing temperatures, vast parts of the world would become barren because of minor climactic variations. Even breeding plants is a kind of evolution...big, fast growing wheat is likely to make us want to grow it more. We are the key environmental factor in that scenario. Most life on Earth has the ability to adapt and change in response the environment, up to a certain point.\n\nSo if someone says that God pre-engineered all life to be able to adapt for its own survival, it is an opinion that is supported by some facts. (medicinal plants, frost hardy plants, creatures with perfect camouflage, interdependency of all species, seeds that only open after a fire, etc)\n\nIf someone else says that life just randomly evolves without any outside guidance, it is also an opinion that is supported by some facts. (useless/harmful biological mutations, randomly mutating diseases, vestigial organs, cancer, etc)\n\nLike all things, in the end it is a matter of faith and your personal beliefs.\n\nI prefer to look at the amazing variety of life that we have in today's world and not worry too much about their extinct ancestors...the laws and properties of life and the universe are what they are.

Because light is needed for photosynthesis which makes energy..since the seeds have no leaves and hence no photosyntheisis they get around by having enough energy material provided within the seed to allow for growth until plant is above ground and has the leaves needed for photosynthesis

what exactly is your question? \nYour potato is growing in the dark because it is what potatoes do if you give them time and water/moisture. If potatoes wouldn't do that there wouldn't be any potatoes around, they would have long ago gone extinct. \nIt is albino because light is needed to induce the syntesis of chlorophyll. It will also grow taller and only have tiny leaf-like structures because under normal circumstances a growing potato experiences permanent darkness is under the ground in the soil. It's only way to develop into a normal potato plant is grow like crazy upwards so it gets out of the ground and gets some sunlight. It is pointless to put energy at this stage in developing leaves. \nIf you never give it light it will grow until all the energy stored in the potato is used up and then it dies.

The genes are still present in the seed even if the seed is damged. The seed wuill contuinue to germinate a long as the right conditions are apparent for growth.

There is a reason why plants only grow so high in nature.  They have to be able to still pump nutrients from the roots to the farthest limb.\n\nBesides, you would be providing a home for rats.

The vegetable itself does not have seeds.\nThe plants they come from go to seed.\nIf you let a carrot, or cucumber, or radish grow too\nlong, it 'goes to seed' as they say on the farm.\nA cluster of seeds usually sprout out of the top\nof the plant for the next set of crops.

Stems and roots have very different structures.\nUnderground stems have structures which you would expect to see in stems growing above ground, e.g. buds. These stems might also turn green when exposed to light as they generate chlorophyll. A good example of an underground stem is the part of the potato plant you eat. The 'eyes' are buds which will sprout. Leave a potao out in the light and it will go green. Several plants use underground stems as storage organs, many (especially grasses) use them to spread, for example couch grass; new plantlets emerge from the buds.\nStems are not specialised for water absorption as roots are and root structures reflect this. There are no buds on roots and they do not go green when exposed to light. Many plants do use roots as storage organs, e.g. carrot, dandelion, etc.
