Question:

What are all of the organelles in a palisade parenchyma cell?

Mesophyll Cells:

Plant leaves are made of cells called mesophyll cells. These cells are organized into two layers, the palisade parenchyma, and the spongy mesophyll. The cells of the palisade parenchyma are organized into neat layers with the primary job of performing photosynthesis for the plant.

Answer and Explanation:

The organelles inside a palisade parenchyma cell are:

  • Nucleus
  • Cytoplasm
  • Ribosomes
  • Smooth endoplasmic reticulum
  • Rough endoplasmic reticulum
  • Golgi apparatus
  • Vesicles
  • Vacuole
  • Mitochondria
  • Chloroplast

Palisade parenchyma cells have especially high numbers of chloroplasts. When viewed under the microscope these cells appear to be packed with small green spheres. These spheres are the chloroplasts. The reason palisade parenchyma cells have so many chloroplasts is that they are the main site of photosynthesis for the plant. Photosynthesis occurs inside the chloroplast, so these cells are filled with them.
