What is the role of cytokinins in plant development?
Correct Answer: Cytokinins are hormones that stimulate cell division and promote shoot development.
  • Step 1: Understand that cytokinins are a type of plant hormone.
  • Step 2: Learn that hormones are substances that help control and regulate various processes in plants.
  • Step 3: Know that cytokinins specifically help stimulate cell division, which is the process where one cell splits into two.
  • Step 4: Recognize that by promoting cell division, cytokinins help in the growth of new shoots, which are the parts of the plant that grow upwards and develop leaves.
  • Step 5: Conclude that cytokinins play a crucial role in helping plants grow and develop by encouraging new growth and cell multiplication.
