Which tissues are present in the hard covering of the seed?
The hard covering of the seed, known as the seed coat, is primarily made up of two tissue layers: the outer layer called the testa and the inner layer called the tegmen. The testa provides protection to the seed while the tegmen helps regulate water uptake and protects the embryo inside.
What is the outer covering of a seed nut or fruit called?
The outer covering of a seed, nut, or fruit is called the pericarp. It typically consists of three layers: the exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer), which can vary in texture and thickness depending on the type of fruit. In the case of nuts, the hard shell enclosing the seed is often referred to as the shell or husk.
What happens to integument after fertilization?
After fertilization, the integument of the ovule undergoes significant changes. It typically develops into the seed coat, providing protection to the developing embryo and endosperm. The integument layers differentiate and harden, creating a barrier that helps prevent desiccation and microbial invasion while allowing for nutrient transfer from the parent plant during seed development. This transformation is crucial for the successful maturation and eventual germination of the seed.
The tough outer layer of a seed is called the?
the seed coat
What is bigger an apple seed or a dandelion seed?
A apple seed is much larger than a dandelion seed.
From what flower part did the seed coat develop?
The seed coat of a plant seed develops from the tissue originally surrounding the ovule. This is called the integument and may have any number of layers depending on the plant.
What is the functions the integument?
The ovule of an angiosperm, which will eventually become a seed, is surrounded by integuments. They are layers of protective sporophytic tissue that eventually develop into the seed coat.
What the meaning of seedling?
A plant reared from the seed, as distinguished from one propagated by layers, buds, or the like.
How are the layers of a coffee fruit similar to those of Earth?
The layers of a coffee fruit, or cherry, can be compared to the Earth's structure in that both consist of distinct, concentric layers. In a coffee cherry, the outer skin (exocarp) is akin to the Earth's crust, while the fleshy pulp (mesocarp) resembles the mantle, and the seed (endocarp) can be likened to the Earth's core. Each layer plays a crucial role in protecting and nurturing the inner seed, similar to how Earth's layers support and sustain life on its surface. Both structures exhibit complexity and interdependence among their layers.

What is present inside the ovule?
Inside the ovule, you will find the female gametophyte, which includes the egg cell. This is surrounded by protective layers such as the integuments, which eventually develop into the seed coat after fertilization. The ovule also contains the structures necessary for fertilization and seed development.
Which model of earth's layer is better orange or peach why?
Both the orange and peach models of Earth's layers have their strengths in visualizing the composition of the planet. The orange model, with distinct layers that mimic the different components of Earth, provides a clear representation for educational purposes. On the other hand, the peach model, with its gradual color transitions, can better illustrate the gradual changes in composition that occur within the layers of Earth. Ultimately, the choice between the two models depends on the specific educational goals and audience preferences.
How does a rosemary reproduce?
screw it look at:: There are three ways to reproduce. The first reproduction is by using 'seed', the second way of reproduction is 'division of roots', and the third way of reproduction is called 'cutting layers'. In warm and sunny time rosemary use ‘seed reproduction’.
Describe the steps of the making of a seed?
The process of seed formation, known as seed development, begins with pollination, where pollen is transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower. Once pollination occurs, fertilization takes place, resulting in the formation of a zygote. The zygote then undergoes multiple rounds of cell division and differentiation to develop into an embryo within the seed. Surrounding the embryo are protective layers, such as the seed coat, which provide protection and support for the developing plant embryo.

Why a soaked seed always germinate but not a dry one?
Soaking a seed will soften the outer layers of the seed and provide moisture to the seed. This triggers a growth response from the seed because it indicates the presence of water which the plant will need to grow. Without the moisture, if the seed germinated it would not have the moisture to grow.
