Answer:
Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
Absorb more thermal energy, and the rough surface will prevent it to reflect efficiently.
Drive less, accelerate slowly, drive until your tank is empty, avoid excessive idling, eliminate wind resistance.
Lysosomes are organelles that float on the cytoplasm and their main function is to secrete waste out of the cell and digest.
Lysosomes are found in eukaryotic cells and yes, they are present in plant cells.
Hope it helped.
