Date of Test:______

Please study the following concepts for the upcoming test on plants. I would encourage you to make flashcards or your own study sheet with this material.

  • Plants have a cell wall made of cellulose, a tough fibrous material.
  • The stem is responsible for the transportation of nutrients.
  • The leaves are responsible for photosynthesis, or making food for the plant.
  • The roots collect water and minerals from the soil.
  • The stomata helps prevent water loss from a plant. It is found in the epidermal tissue.
  • Guard cellsregulate the opening and closing of the stomata.
  • The epidermis of a plant is similar to the skin of an animal (derm = skin)
  • The two types of vascular plant tissue are xylem and phloem.
  • Sugars (made by photosynthesis) are transported throughout the plant by the phloem. (remember that PHLOEM FLOWS DOWN)
  • Water is transported from the roots through the rest of the plant by the xylem.
  • The leaf is the broad, flat organ that traps light energy for photosynthesis.
  • The cuticleis the protective, waxy layer covering most fruit, leaves and stems.
  • The seed is the structure that contains an embryo along with a food supply and is covered by a protective coat.
  • The stemprovides structural support for upright growth.
  • A vascular plantcontains tissues of tubelike, elongated cells through which water and food are transported.
  • The root absorbs water and minerals from the soil.
  • There are 4 main types of plant tissue:

-Epidermal – the outermost layer of the plant; contains stomata.

-Ground – used for transport, storage and photosynthesis (think of a carrot- this is mostly cortex, which is a type of ground tissue- used for storage of sugars)

-Vascular – consists of xylem and phloem for transport of water and sugars.

-Meristematic – found in rapidly growing areas of the plant (the budding parts of trees or the tips of roots)
