Ground tissue
Ground Tissue
Ground tissue (/graʊnd ˈtɪʃuː/) is one of the three types of plant tissue systems, the others being vascular tissue and dermal tissue. The term "ground tissue" is derived from the Latin "grundus", meaning "base" or "foundation", reflecting its role as the bulk of the non-dermal, non-vascular tissues in plants.
Definition
Ground tissue is a type of tissue found in plants that makes up the majority of the plant's body. It is responsible for carrying out most of the plant's metabolic functions, including photosynthesis, storage, and support. Ground tissue can be further divided into three types: parenchyma, collenchyma, and sclerenchyma.
Function
The primary function of ground tissue is to fill space in the plant body and provide support. It also plays a crucial role in photosynthesis, storage, and regeneration. The different types of ground tissue (parenchyma, collenchyma, and sclerenchyma) each have unique functions and characteristics.
Parenchyma
Parenchyma (/pəˈrɛŋkɪmə/) is the most common type of ground tissue. It is involved in many functions, including photosynthesis, storage, and tissue repair.
Collenchyma
Collenchyma (/kɒlɛnˈkaɪmə/) provides support for the plant, particularly in regions of growth. It is flexible and can stretch as the plant grows.
Sclerenchyma
Sclerenchyma (/sklɪrɛnˈkaɪmə/) provides the main structural support to the plant. It is composed of cells with thick, lignified walls, making it the strongest of the three types of ground tissue.
