A botanist examines a cross-section of a young stem. She observes a layer of cells just beneath the epidermis that provides flexible support during primary growth, and scattered bundles containing tissues responsible for long-distance transport. Which tissue types are most likely being described?

  • A: Epidermis and Parenchyma.
  • B: Collenchyma and Vascular tissue.
  • C: Sclerenchyma and Dermal tissue.
  • D: Pith and Cortex.

Explanation

The text states that 'collenchyma cells just beneath the epidermis strengthen many stems during primary growth' flexible support . It also states that 'Vascular tissue runs the length of a stem in vascular bundles' long-distance transport . Therefore, collenchyma and vascular tissue are the most likely descriptions.
