Can anyone give me 5 examples of spme specialised plant cells, describe what it is and its function?
1. Parenchyma Cells. These cells are the most general of plant cells. They consist of thin flexible cell walls. They contain a large central vacuole and can carry out most of the metabolic functions of the plant. Mesophyll cells of the leaf are parenchyma cells. The fleshy tissue of most fruits also contain much parenchyma. 2. Collenchyma Cells. These cells have a much thicker primary wall than the parenchyma cell. Grouped in strands or cylinders they support young plants. 3. Sclerenchyma Cells. Function in support of the plant. They contain a thick secondary wall containing lignin. For all intent and purpose these cells function best when dead. 4. Tracheids. These are water conducting elements. These cells are dead and are found along with vessel elements making up the plants xylem. 5. Sieve-tubes. These function in carrying food throughout the plant. They are kept alive and nourished by companion cells. These are found in the plants phloem.
