Plants consist of organs such as roots, stems, and leaves. These organs work together to form organ systems. These can perform a variety of functions that plants require to survive and grow, such as transporting substances around the plant. Plant tissues are the building blocks of organs.

  • The epidermis covers the entire plant.
  • Palisade mesophyll is the leaf part most responsible for photosynthesis.
  • A spongy mesophyll tissue that is also in the leaf and contains air big spaces for gases to diffuse in and out of cells.
  • Water, minerals, and food are transported through roots, stems, and leaves by xylem and phloem.

Several different types of tissue make up a leaf. The leaves are made up of epidermal tissue, mesophyll, xylem, and phloem tissues.
