Questions and Answers

What is a key difference between sclerenchyma cells and columnar cells?

  • Sclerenchyma cells are involved in photosynthesis, while columnar cells are involved in transport and secretion.
  • Sclerenchyma cells are tall and column-like, while columnar cells are long and narrow.
  • Sclerenchyma cells are short and irregularly shaped, while columnar cells are long and narrow.
  • Sclerenchyma cells are primarily found in mature plants, while columnar cells are found throughout the plant. (correct)

    • Why is understanding the differences between sclerenchyma and columnar cells essential for agricultural practices?
