Both plant and animal cells have the following organelles: mitochondrion, golgi apparatus, ribosomes, nucleus, cell membrane, rough and smooth ER and cytoplasm.
In animal cells, cell wall is absent unlike in plant cells. The plant cell has a regular shape whilst the animal cell has an irregular shape. Animal cells do not have chloroplasts whilst the plant cells do. In animal cells, small or no vacuole is present whilst the plant cells have a large vacuole
Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.
The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).
Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.

If this is a true or false question then the answer is true.
Answer:
The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. Approximately 3.5 percent of seawater is composed of dissolved compounds, while the other 96.5 percent is pure water. The chemical composition of seawater reflects such processes as erosion of rock and sediments, volcanic activity, gas exchange with the atmosphere, the metabolic and breakdown products of organisms, and rain.
Explanation:
Answer: Xylem fibers and xylem parenchyma are the elements of the xylem which is a vascular tissue in plants.
Explanation:
Xylem fibers are dead cells whereas the xylem parenchyma are living cells.
Xylem fibers are responsible for providing structural support to the entire structure of xylem whereas the xylem parenchyma is involved in conducting of water and minerals.
In xylem fibers the lignin is present whereas it is absent in xylem parenchyma.
