Worked practice questions

Along with climate, the major determinant of plant distribution and growth is:

  1. Soil quality
  2. Soil colour
  3. Soil weight
  4. Soil noise
Show answer and solution

Correct answer: A. Soil quality

1. Plants draw water and minerals from the ground. 2. What the ground offers sets what can grow. 3. So it is soil quality. _Source: OpenStax Biology 2e, Chapter 31, Soil and Plant Nutrition._

Plant roots take up water from the soil through their:

  1. Root scars
  2. Root hairs
  3. Root caps
  4. Root nodes
Show answer and solution

Correct answer: B. Root hairs

1. Fine extensions greatly increase the absorbing surface. 2. Water then moves up through the xylem. 3. Those extensions are root hairs. _Source: OpenStax Biology 2e, Chapter 31, Soil and Plant Nutrition._

The essential elements a plant needs are divided into how many groups?

  1. 2
  2. 3
  3. 4
  4. 5
Show answer and solution

Correct answer: A. 2

1. Some are needed in large amounts and some in traces. 2. That gives macronutrients and micronutrients. 3. So there are 2 groups. _Source: OpenStax Biology 2e, Chapter 31, Soil and Plant Nutrition._
