Plant Tissue Systems. Plants do have a higher level of structure called plant tissue systems. A plant tissue system can be defined as a functional unit, which connects all organs of a plant. Like animal tissue system, plant tissue system is also grouped into various tissues based on their functions.
MONOCOTS do not have lateral meristems. Lateral meristems come in two basic types: Vascular cambium; meristematic tissue located between the xylem and phloem. The vascular cambium makes new xylem and phloem cells. Cork cambium; meristematic tissue located just below the bark in woody dicot stems.
parenchyma cells, and sometimes fibers). Tissues are organized into three tissue systems: the dermal, vascular, and ground systems. All three tissue systems occur in leaves, stems, and roots. The various kinds of cells that compose plant tissues and their characteristics, location, and function are summarized in the handout
Xylem is composed of cells of four different types:tracheids;vessels or tracheae; xylem parenchyma; xylem sclerenchyma.Except xylem parenchyma,all other xylem elements are dead & bounded by thick lignified walls.Of these four types of cells of xylem,most important cells are vessels.Vessels are very long tube-like
Some tissues are blood (Fluid connective tissue), xylem and phloem. (conductive tissue) etc. Plants and animals have different types of tissues. Plant Tissues. Plants body is composed of different types of tissues to perform different functions. Various types of plants tissue are discussed under:- A) Meristematic Tissue:-.
PLANT TISSUES. Definition of tissue. Tissues are group of similar cells, having the same origin and performing a specific function. Definition of organ. A group of tissues that Depending on the location, Meristematic tissue can be grouped into three types- apical meristem, The two types of complex permanent tissue are:.
113. Tissues and Other Levels of Organization. BIOLOGY. Notes. A group of cells with similar origin, structure and function is called tissue. e.g. bone, muscle in animals and meristem in tips of root and shoot in plants. 5.2 THE PLANT TISSUES. The plant tissues are mainly of two types: 1. Meristematic (Gk. meristos : dividing).
Plant tissue types ground tissue - thin walled parenchyma cells in interior of root and shoot - which function in storage, photosynthesis, and secretion often capable of giving rise to other tissue types dermal tissue - covers entire plant body (more detail later) vascular tissue - xylem - for conducting water and dissolved
