Write the function of each type of cell in the plant.
1. Tracheids
2. Xylem vessels
3. Xylem parenchyma cells
4. Xylem sclerenchyma cells
5. Sieve elements
6. Companion cells
7. Phloem parenchyma cells
8. Phloem sclerenchyma cells
Answers
Answer:
xylem helps in water condition because parts of xylem are dead except the xylem parenchyma rest all are dead whereas all the parts of phloem helps in conduction of mineral and organic acids except the sieve elements because sieve elements are dead all the functions of sieve elements are done by companion cells also the function of sclerencha is to provide mechanical strength to the plant

Answer:
1. Wood cell walls. Tracheids are the water-conducting and mechanical supporting cells of gymnosperms; water is transported longitudinally through endplates and laterally through pits. Angiosperm vessels function primarily to transport water and are individually shorter than tracheids.
2. Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential 'supporting' role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.
3. Xylem parenchyma is an element of complex tissue called “Xylem”. Parenchyma cells of xylem are mainly involved in the storage of carbohydrate, fats and water conduction. Plant tissues can be categorised based on their structure and functions performed.
4. Sclerenchyma cells are strong, thick cells that provide most of the support in a plant. They are known to have extremely thick cell walls and do not participate in many of the other activities of the developing plant, such as photosynthesis, because their focus is strictly on support and structure.
5. Sieve Elements (of Phloem) Sieve elements are specialized cells that function in the conduction of sugars. They are typically associated with parenchyma and often some sclerenchyma in a common tissue known as phloem.
6. any of a number of specialized parenchymal cells adjacent to a sieve tube in the phloem of flowering plants, believed to regulate the flow of nutrients through the tube.
7. Phloem parenchyma cells, called transfer cells and border parenchyma cells, are located near the finest branches and terminations of sieve tubes in leaf veinlets, where they also function in the transport of foods.
8. The phloem sclerenchyma is comprised of sclerenchyma cells that are rather associated with providing mechanical support than conducting materials. It includes the phloem fibers and the sclereids. The phloem fibers are one of the supportive cells of the phloem tissue; the others are sclereids.
