Karen, a famous botanist, propagates thousands of spider plants in her greenhouses. She uses a small cluster of plant cells and grows them first in a nutrient base. Just a few cells eventually grow into a new plant. Which explanation BEST describes how this type of asexual reproduction can occur in many plants? A) Plants can grow in a nutrient medium and animal cells cannot. B) Plant cells go through the cell cycle a a much faster rate than any other types of cells. C) Plant cells are undifferentiated and under certain conditions, can differentiate into all three plants tissues. D) Plant cells differentiate immediately after fertilization; a small clump will contain all the cell types needed to grow a new plant.
