Does the weight of a seed affect how fast a plant grows? A seed is “the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.” (Dictionary.com) Seeds go through a process, called germination, to grow. The seed first has its roots break out and grab hold of the soil. After the roots have a hold of the soil a small plant will sprout from the ground. All plants go through the germination process. (How do Seeds Sprout?) The hypothesis is: If the weight of a seed affects the rate the plant grows, then a heavier seed will grow faster. Seeds are made up of only a few components. The outer layer of the seed is called the seed coat. Seed coats protect the seed from anything that can harm it. The inside of a seed includes the cotyledon and the embryo. The cotyledon stores all of the nutrients and food for the plant and is the part of the embryo and turns into the first leaves of the plant. These leaves are photosynthetic and collect sunlight which it uses to collect nutrients. (Cotyledon: Definition and Function) The food stored inside the cotyledons usually consists of starches and is called endosperm. (Parts of the Seed) So the amount of cotyledon in a seed …show more content…
This is why most plants and trees will produce a lot of seeds that can spread everywhere and even can travel hundreds of miles before they germinate. (Seed Dispersal: How do Plants Spread Their Seeds?) There are multiple kinds of seeds that come in all shapes and sizes. Seeds and plants can also adapt to the environment that they are in. Seeds can grow through periods where they do not germinate. When seeds do this it means they are dormant. Seeds can only germinate when the temperatures are just right for that specific seed. (Seed Germination) When seeds are planted in the wrong temperature they will fail to germinate or
