Why do seeds differ?
Seeds come in different sizes and shapes across plant species. Depending on geographical location and the prevailing biotic and abiotic factors, seed size and shape can vary even within a species. Even within same species, for example corn, the size, shape, and shininess of the seeds vary.
Are seeds from the same plant genetically identical?
Seed Grown Plants Are Genetically Diverse Each each ova is also genetically different from the others on the plant, too. Just like human siblings are not genetically identical, seeds do not grow into genetically identical plants.
Why are plants grown differently?
Sometimes, two plants of the same species will grow differently. Usually, this is because they are in different light and moisture conditions, but it may be just differences in individual plants. Just like some people are tall and some are short.
Why do different plants have different number of seeds in their fruits?
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilisation. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango.
Why do plants produce many seeds?
Why do plants produce seeds? Plants produce many seeds to ensure the continuation of the species. The seed contains the embryo that will later grow into a new plant.
Why do some plants produce more seeds than others?
The longstanding belief as to why some plants produce big seeds and others small seeds is that in this case bigger-is-better, since large seeds have a better chance of survival. In contrast, small-seeded species have an advantage at favorable sites, just because they’ve got more seeds in the game.”
Are all seeds in one fruit genetically identical?
No, the seeds are not genetically identical. Each seed come from the fertilization of an ovum with a sperm from a separate pollen grain. Since each pollen grain can come from a different plant, the seeds will generally differ from one another.
Why are different plants growing in different places?
Plants and animals are adapted to live in specific environments. They need certain temperatures to survive. Plants need the right amounts of rain and sunlight. This is a place where plants are grown and displayed.
Why do different plants grow at different rates?
Some plants grow faster than others due to the different adaptations they have. Plants have evolved to be well adapted to their environments.
Why do some fruits have one seed and others have many seeds?
