PLANT TISSUES

• This refers to cells that work together to perform a specific function.

  Tissue
• What are the three basic tissue systems?

  1. Dermal
  2. Ground
  3. Vascular
• What is the growing tissues at the tips of roots and stems, responsible for the increase in length (elongation) of the stems and roots?

  Apical Meristems
• This is a specific growing region where plant growth only occurs.

  Meristems
• It refers to the increase in length of the shoot and root.

  Primary Growth
• It refers to the increase in diameter or girth of the shoot and root.

  Secondary Growth
• It is a form of meristematic tissue that controls the growth of plants in terms of length.

  Primary Meristem
• It is responsible for the increase in stem girth and thickness.

  Secondary Meristem
• This carries out long-distance transport of materials between roots and shoots.

  Vascular Tissue System
• What are the two vascular tissues?

  1. Xylem
  2. Phloem
• This vascular tissue conveys water and dissolved minerals upward from roots into the shoots.

  Xylem
• This vascular tissue transports organic nutrients from where they are made to where they are needed.

  Phloem
• These are tissues that are neither dermal nor vascular.

  Ground Tissue System
• Ground tissue internal to the vascular tissue is pith; while ground tissue external to the vascular tissue is cortex.
• This tissue covers and protects the plant.

  Dermal Tissue
• This tissue transport water, minerals, and sugars.

  Vascular Tissue
• This tissue serves as a site for photosynthesis, supports vascular tissue, and stores nutrients.

  Ground Tissue
• It forms the outside covering of a plant. It covers all parts of the plant roots, stems, and leaves.

  Dermal Tissue
• What kind of tissue is the Epidermis?

  Dermal Tissue
• It is a waxy substance that forms a layer.

  Cuticle
• It is formed by epidermis and are responsible for the absorption of water and other nutrients needed by the plant.

  Root Hair
• This tissue is either undifferentiated or incompletely differentiated; they continue to divide and contribute to the growth of the plant.

  Meristematic Tissue
• Apical meristem is an example of...

  Meristematic Tissue
• This tissue consists of plant cells that are no longer actively dividing.

  Permanent Tissue
• The meristematic tissues divide and differentiate to form the permanent tissues.

  True
• It is a type of meristem in woody plants which allow stems and roots to increase in diameter. These are located near the outside of stems and roots, which replaces the epidermis, and add vascular tissue.

  Lateral Meristems
• It is a type of lateral meristem that is located between the Xylem and Phloem; responsible for the production of additional vascular tissues.

  Vascular Cambium
• It is a type of lateral meristem that is lcoated outside the Phloem; responsible for the production of cork for the protection of the plant.

  Cork Cambium
• These cells are dead cells providing protection and preventing rapid loss of water.

  Cork cells
• What are the main tissue types of Ground Tissue?

  1. Parenchyma
  2. Collenchyma
  3. Sclerenchyma
• It is a type of ground tissue making up most of the non-woody parts of a plant.It has thin walls of cellulose. 


  Parenchyma
• This ground tissue is the most abundant and least structurally specialized tissues. They are usually elongated having a large vacuole with thin and flexible cells walls. Its cells can divide and become more specialized tissues for several functions.

  Parenchyma
• This ground tissue are cells responsible in supporting the growing parts of the plants. The cell walls of Collenchyma cells are irregular in shape and thicker (due to additional cellulose) compared to those of Parenchyma cells. The thick walls are composed of stretchable cells, which provide flexible support.

  Collenchyma
• This ground tissue are cells which provide support for the non-growing parts of the plants. They have very thick and rigid/lignified (non-stretchable) cell walls.

  Sclerenchyma
