Ground tissue
Answers
The three types of ground tissue, parenchyma, collenchyma, and sclerenchyma, function in photosynthesis, storage, regeneration, support, and protection.
It forms, for example, the cortex and pith of stems, the photosynthetic tissue layer within the epidermis of the leaves (mesophyll), the cortex of roots, the pulp of fruits, and the endosperm of seeds. Parenchyma is composed of relatively simple, undifferentiated parenchyma cells.
It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
The major cells of the ground tissue are parenchyma cells, which function in photosynthesis and nutrient storage. They have thin walls, many chloroplasts, and large central vacuoles, and they form the mass of most leaves, stems, and roots. Another cell of the ground substance is the sclerenchyma cell.
Answer:
The three types of ground tissue, parenchyma, collenchyma, and sclerenchyma, function in photosynthesis, storage, regeneration, support, and protection.
The ground tissue of plants includes all tissues that are neither dermal nor vascular. It can be divided into three types based on the nature of the cell walls.
Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root.
Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.
Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant.[1]
