HEY!

Sclerenchyma:

• The cells of the Sclerenchyma tissue are dead.
• Air filled cavities are absent.
• The cell wall is very thick due to the deposition of lignin.
• The cells of this tissue can be in different shapes and sizes.
• They are generally located in the leaf veins, hard coverings of the seeds and can also be found surrounding the vascular bundle.

Aerenchyma:

• Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants.
• It allows exchange of gases between the shoot and the root.
• It has large air-filled cavities.
• Aerenchyma is also widespread in aquatic and wetland plants.
