Hint: Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.
Complete Answer:
- Parenchyma is simple ground tissue with Unspecialized and living cells. The cells are thin-walled polyhedral, isodiametric living cells with sufficient cytoplasm. There are various shapes of the cells, but generally, they are isodiametric. These cells can be uninucleated or multinucleated. The cell wall is made up of cellulose.
- These tissues play a role in storage, photosynthesis, gaseous exchange, and much more but do not provide mechanical support to the plant as they lack cell wall thickening or lignin deposition.
- They have cellulose cell walls without any thickening or lignin deposition. Well developed intercellular spaces are a characteristic feature of parenchymatous cells. Aerenchyma is an example of parenchymatous tissues with intercellular space.
So, is ‘Intercellular spaces’ is the correct answer.
Additional information:
1) Parenchyma cells have thin primary walls and usually remain alive after they become mature. These cells are usually found in the cortex, pericycle, pith, and medullary rays in primary stem and root.
2) 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.
3) Sclerenchyma cells have thick lignified secondary walls, this is why these are called non-living tissues or dead tissues. Sclerenchyma provides the main structural support to a plant.
Note: The ground tissue of plants includes all tissues except dermal or vascular tissues such as xylem and phloem, which can be divided into three types based on the nature of the cell walls.
