Plant Tissues Meristematic tissues actively dividing by mitosis
Plant Tissues Meristematic tissues – actively dividing by mitosis to form new cells. They DO NOT differentiate to perform any other specific function. Permanent tissues – arise from cells formed by mitosis from the meristematic tissue that have differentiated so that they have a particular structure suited for the role that they would play in the plant.
Meristematic Tissues Tissue Type Location Function Apical Meristem Tips of roots and stems. Through cell division they produce new cells for growth, repair and replacement of damaged or wornout tissues. Lateral Meristem Found between xylem and phloem in the vascular bundles of stems. Through cell division the produce new cells for growth, repair and replacement of damaged or wornout tissues. Appearance
Permanent Tissues Tissue Type Location Function Epidermis Lines the surface of -They protect plant roots, stems and organs. leaves. - May be modified to form guard cells or root hair cells. Collenchyma Found in stems and Provides strength leaves. and support to the aerial parts of the plants. Appearance
Permanent Tissues Tissue type Location Function Parenchyma Fills up large spaces between other tissues in roots and stems. -Serves as packaging tissue. -Stores food in the form of starch and other sugars. -Allows for movement of water and gases through their intercellular spaces. Chlorenchyma Found in leaves. -Contains chlorophyll for manufacture of organic compounds (e. g. glucose) Schlerenchyma Found in leaves, stems, roots and fruit of plants. Provides mechanical support to plant. Appearance
Permanent Tissues Tissue Type Location Function Xylem Found in roots, stems and leaves. -Transports water and minerals through the plant. -Provides support and strength to the plant. Phloem Found in roots, stems and leaves. -Transports manufactured food from leaves to all parts of the plant. Appearance
