Which of the following statement about conifers is correct?
Correct answer: D. Excrete some of the waste materials directly into soil, occasionally using them as a chemical weapon against other competing plants.
- A. Stored excretory products in vacuoles, at a concentration that leads to crystal formation.
- B. Accumulate waste in leaves, which fall in autumn.
- C. Production of black wood in the center.
- D. Excrete some of the waste materials directly into soil, occasionally using them as a chemical weapon against other competing plants.
Explanation
Conifers can release certain chemical wastes into the soil through their roots, and some of these substances may inhibit competing plants, a form of chemical defence. The likely distractor is black wood at the centre, but that describes heartwood formation and is not the characteristic excretory process stated here.
