Answer:
The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure. The cell wall is so rigid and covered by the cell that protects it that provides shape and support to it. The plant cell also made up of molecules and these are called cellulose. These cellulose structured into the fibers that are called micro-fibrils
Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
