What divisions make up the seed plant portion of the above phylogeny?
The seed plant portion of the phylogeny includes the gymnosperms and angiosperms. Gymnosperms are a group of seed-producing plants with exposed seeds, such as conifers and cycads, while angiosperms are flowering plants that produce seeds enclosed within a fruit.
Which tissues are present in hard covering of seeds?
The hard covering of seeds is primarily composed of the seed coat, which is made up of specialized tissues like the testa and the tegmen. These tissues provide protection to the seed during dormancy and help regulate water intake when germination occurs. Additionally, the endosperm or cotyledons found within the seed also contribute to the overall structure of the seed coat.
Are seed plants multicellular?
Yes, seed plants are multicellular organisms. They are composed of multiple cells that form various tissues and organs, such as roots, stems, and leaves. This multicellularity allows them to perform complex biological functions necessary for growth, reproduction, and survival.
What is a vitreous seed?
A vitreous seed is a small, opaque structure found in the vitreous humor of the eye. It is usually composed of proteins and cells that have clumped together due to various reasons such as aging, inflammation, or trauma. Vitreous seeds can sometimes float around in the vitreous humor and may cause visual disturbances or floaters.
The tough outer layer of a seed is called the?
the seed coat
Did seed is it a living thing or non- living thing?
A seed IS a living thing. It is composed of a multicellular embryo plant with food (called the endosperm). It has a life expectancy and will eventually die, particularly if exposed to extreme temperatures.

What is the wor meaning of pistil?
An epistle., The seed-bearing organ of a flower. It consists of an ovary, containing the ovules or rudimentary seeds, and a stigma, which is commonly raised on an elongated portion called a style. When composed of one carpel a pistil is simple; when composed of several, it is compound. See Illust. of Flower, and Ovary.

Is a hazelnut a nut or a seed?
The seed is the part of the nut known as walnut (Juglans spp) that is eaten.Specifically, nuts are considered fruits. Within the category of fruits, there are hard-shelled and soft-skinned members. Walnuts represent an example of hard-shelled fruits (or nuts) and are composed of a hard outer fruit and an edible inner seed.A popular example of soft fruits are apples (Malusspp).
What is palm kernel seed?
Palm kernel seed is the seed of the oil palm tree (Elaeis guineensis), specifically the seed found within the fruit of the tree. It is primarily composed of oil-rich kernels and is a significant source of palm kernel oil, which is widely used in food products, cosmetics, and industrial applications. Additionally, palm kernel cake, a byproduct of oil extraction, is often used as animal feed due to its high protein content. The cultivation and processing of palm kernel seeds are integral to the palm oil industry.
What is a seed coat of a seed?
