Matter can recycle through the biosphere because: a) matter is passed out of the body as waste. b) matter is assembled into chemical compounds. c) biological systems do not use up matter, they transform it. d) biological systems use only carbon, oxygen, hydrogen and nitrogen

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
