What signals the end of Germination?
The end of germination is signaled by the emergence of the radicle, the first root of the seedling, from the seed coat. At this stage, the seedling begins to obtain nutrients from the soil and photosynthesize to support its growth.
What is the function of scutellum?
The scutellum is a specialized structure in seeds that absorbs nutrients and transfers them to the growing embryo during germination. It acts as a nutrient reservoir to support early seedling growth.
Is germination between seed to sapling or seed to plant?
Germination refers specifically to the process that occurs from seed to seedling, not directly to a mature plant. During germination, a seed absorbs water, swells, and eventually breaks open, allowing a seedling to emerge. The seedling then develops further into a sapling and eventually matures into a full plant. Thus, germination marks the initial phase of growth from seed to seedling.
How does cotton affect the germination of seed?
Cotton can inhibit seed germination by creating a barrier that limits water absorption or by producing allelopathic compounds that inhibit seedling growth. Additionally, cotton fibers can physically impede seedling emergence, hindering the germination process.
Function of scutellum in a maize seed?
The scutellum in a maize seed is responsible for absorbing nutrients from the endosperm, providing nutrients to the growing embryo. It also helps in the mobilization of stored reserves during germination, supporting the initial growth of the seedling.
How does mold affect the germination process of seeds?
Mold can hinder the germination process of seeds by competing for nutrients and oxygen, leading to reduced seedling growth and potential seedling death.
What signals the end of Germination?
The end of germination is signaled by the emergence of the radicle, the first root of the seedling, from the seed coat. At this stage, the seedling begins to obtain nutrients from the soil and photosynthesize to support its growth.
How does mold affect the germination of seeds on a paper towel?
Mold can hinder the germination of seeds on a paper towel by competing for nutrients and oxygen, leading to reduced seed growth and potential seedling death.
At what point in the growth stage is the plant considered a seedling?
At point of germination
What part do they play in early development of the seedling?
The endosperm provides nutrients and energy for the developing seedling, while the cotyledons (seed leaves) help in the absorption of stored nutrients and provide energy for early growth. The seed coat protects the embryo from damage and desiccation during germination.

Is soil necssery for seed germination?
Soil is not always necessary for seed germination, as some seeds can germinate in alternative growing mediums like peat moss, vermiculite, or perlite. However, soil provides seeds with the essential nutrients, moisture, and support needed for successful germination and seedling growth.
Function of scutellum in a maize seed?
The scutellum in a maize seed is responsible for absorbing nutrients from the endosperm, providing nutrients to the growing embryo. It also helps in the mobilization of stored reserves during germination, supporting the initial growth of the seedling.
What energy required for a seedling to push up out of the ground comes from?
The energy required for a seedling to push up out of the ground mainly comes from stored reserves in the seed itself. As the seed absorbs water and nutrients from the soil, it uses this stored energy to fuel the initial growth and emergence of the seedling. This process is known as germination.
Why do you put seeds in soil?
Seeds are planted in soil because they require the nutrients, moisture, and stability that soil provides for germination and growth. Soil also offers support and protection to the developing seedling as it grows into a mature plant.
