The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The polar ice cap is an area of very low temperature and the surface is mostly covered by ice.

  • The vast polar ice caps the earth's northern and southern limits.
  • This is the region of the Arctic and Antarctic circle.
  • This region receives diffused solar radiation from the sun.
  • This is why they rarely warm up.
  • The region of the equator has no ice because they receive direct sunlight.
  • The soil here is frozen.
