Sclereid
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. The presence of numerous sclereids form the cores of apples and produce the gritty texture of pears.
Although sclereids are variable in shape, the cells are generally isodiametric, prosenchymatic, forked or elaborately branched. They can be grouped into bundles, can form complete tubes located at the periphery or can occur as single cells or small groups of cells within parenchyma tissues.
When compared with most fibres, sclereids are relatively short. Characteristic examples are brachysclereids or the stone cells (called stone cells because of their hardness) of pears (Pyrus communis) and quinces (Cydonia oblonga) and those of the shoot of the wax plant (Hoya carnosa). The cell walls fill nearly all the cell's volume. A layering of the walls and the existence of branched pits is clearly visible. Branched pits such as these are called ramiform pits. The shell of many seeds like those of nuts as well as the stones of drupes like cherries or plums are made up from sclereids.

what are plant cell ? - Sclerenchyma
Sclerenchyma Sclerenchyma is a dead tissue. The cells have lignified secondary walls. They lack protoplasts. On the basis of origin, structure and function, sclerenchyma is divided into two types -- sclereids and fibres. The sclereids are different from fibres in the following respects. Sclereids are shorter whereas fibres are longer. Sclereids possess numerous pits as compared to the fibres. www.edufine.net

SCLEREIDS - Pronunciation, Meaning, and How to Use It in 2023
Sclereids are a type of plant cell that provide mechanical support and protection to various plant tissues.
They are characterized by their thick, lignified cell walls and small, irregular shapes.
Sclereids can be found in the ground tissue of plants, such as the seed coats, fruit walls, and nutshells, as well as in the vascular tissue, such as the xylem and phloem.
They play a crucial role in enhancing the strength and rigidity of plant structures, helping them withstand mechanical stress and prevent water loss.
The diverse shapes and arrangements of sclereids contribute to the unique textures and hardness of different plant parts.
Pronunciation:
To correctly pronounce 'sclereids', you can say [skli-ree-ids], [skleer-ee-ids], or [sklair-ee-ids].
Test yourself by speaking the following examples:
1. Sclereids provide mechanical support to the seed coats
2. The fruit walls contain sclereids for protection
3. Nutshells have sclereids that contribute to their hardness and strength
4. The xylem tissue contains sclereids that add rigidity to the plant structure
5. Sclereids play a role in preventing water loss in plants

Sclerenchyma
Sclerenchyma is a dead tissue. The cells have lignified secondary walls. They lack protoplasts. On the basis of origin, structure and function, sclerenchyma is divided into two types -- sclereids and fibres. The sclereids are different from fibres in the following respects. Sclereids are shorter whereas fibres are longer. Sclereids possess numerous pits as compared to the fibres.

Sclerenchyma are dead mechanical Tissue.
Based on Origin and Structure, Sclerenchyma are of 2 types :
Sclerenchymatous Fibre and Sclereids.
Sclerenchymatous Fibres are group of elongated, pointed cells, which usually occur in group. Based on source and Economic importance, Sclerenchymatous Fibres are of 3 types : Surface Fibres, Bast Fibres and Wood Fibre or Xylary Fibre.
Xylary Fibres are of 2 types : Libriform Fibres and Fibre Tracheids.
Sclereids or Stone cells are also Lignified cells which may occur singly or in group. Based on shape, they are mainly of 2 types : Monomorphic and Polymorphic
Based on shape, Sclereids are of different types like Brachysclereids or Grit cells, Macrosclereids or Rod Cells, Osteosclereids, Astrosclereids or Stellate Sclereids, Trichosclereids, Filiform Sclereids or H shaped Sclereids.

SCLEREIDS - Pronunciation, Meaning, and How to Use It in 2023
Sclereids are a type of plant cell that provide mechanical support and protection to various plant tissues.
They are characterized by their thick, lignified cell walls and small, irregular shapes.
Sclereids can be found in the ground tissue of plants, such as the seed coats, fruit walls, and nutshells, as well as in the vascular tissue, such as the xylem and phloem.
They play a crucial role in enhancing the strength and rigidity of plant structures, helping them withstand mechanical stress and prevent water loss.
The diverse shapes and arrangements of sclereids contribute to the unique textures and hardness of different plant parts.
Pronunciation:
To correctly pronounce 'sclereids', you can say [skli-ree-ids], [skleer-ee-ids], or [sklair-ee-ids].
Test yourself by speaking the following examples:
1. Sclereids provide mechanical support to the seed coats
2. The fruit walls contain sclereids for protection
3. Nutshells have sclereids that contribute to their hardness and strength
4. The xylem tissue contains sclereids that add rigidity to the plant structure
5. Sclereids play a role in preventing water loss in plants

Sclereid
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. The presence of numerous sclereids form the cores of apples and produce the gritty texture of pears.
Although sclereids are variable in shape, the cells are generally isodiametric, prosenchymatic, forked or elaborately branched. They can be grouped into bundles, can form complete tubes located at the periphery or can occur as single cells or small groups of cells within parenchyma tissues.
When compared with most fibres, sclereids are relatively short. Characteristic examples are brachysclereids or the stone cells (called stone cells because of their hardness) of pears (Pyrus communis) and quinces (Cydonia oblonga) and those of the shoot of the wax plant (Hoya carnosa). The cell walls fill nearly all the cell's volume. A layering of the walls and the existence of branched pits is clearly visible. Branched pits such as these are called ramiform pits. The shell of many seeds like those of nuts as well as the stones of drupes like cherries or plums are made up from sclereids.

1968
by: SecretMarching down the road I look back to see who is lost
Forget about the past, I will leave my name behind my back, behind me, forsaken
Head against the walls I will burn every fucking flag in front of everyone, betrayed.
To hear their screams louder
Blood all over the ground, fertilizer for the disease
It grows high, it grows lonely
Another riot is born right now, another widow cry in front of me betrayed
Isolated from this tragedy. Fated for a deeper void.
There's no light to see outside just a dark night filled with all your fears
Today's ending and there's no light to see anymore, everything is gone
