• Transpiration is the carrying of water from the roots to the leafs and released out of pores in the leaf. Its function is to give off excess water taken up for plant growth and photosynthesis.
  • Turgor pressure is the pressure pushed up against the cell wall.
  • Vascular tissue is made up by the xylem and phloem. By means of vascular tissue, nutrients and water are transported throughout the plant. 
  • Soil contributes to plant growth immensely. Soil contains the nutrients and moisture that plants need to grow and survive. Photosynthesis allows for plants to grow and is obtained through the soil.
  •  The casparian strip is like the guard cell of the vascular tissue. It blocks solutes and water from entering the vascular tissue and thus into being transported throughout the plant.
  • The xylem is one of the two vascular tissues and serves the main purpose of transporting water and dissolved ions upwards throughout the plant. It's structure looks like this. Composed off a membrane and tracheids which are cells that transport water through the xylem tubes.

  • Gas exchange is through the stomata and guard cells. The stomata are holes in the leaf epidermis that allows gas exchange while the guard cells protects the stomata by closing and opening by swelling. There are two guard cells to every stoma. So the stomata is the hole and the guard cells allow for things to enter or leave the stomata.
