PLANT TISSUES
Two Major Categories of Plant Tissues
1. Meristematic Tissue. A. Apical Meristems B. Lateral Meristems
2. Permanent Tissue A. Dermal (Surface Tissue) B. Fundamental Tissue (Ground Tissue) C. Vascular Tissue
MERISTEMATIC TISSUE
Composed of immature cells and are regions of active cell division. small, thin walls and rich in cytoplasm. Found in the growing tips of the roots and stem.
A. Apical Meristems * Responsible for increase in length of the plant body.Found on root tips and apical buds
B. Lateral Meristems * Responsible for increase in girth or diameter * Ex: Cambium present in woody plants and produce the cork
PERMANENT TISSUE
A. Dermal (Surface Tissue) * Forms the protective outer covering of the plant body
A.1. Epidermis * Produce cutin to protect plants against loss of water * Produce root hairs for absorption of water and minerals
A.2. Periderm * Replaces the epidermis * Constitutes the corky outer bark of old trees.
PERMANENT TISSUE
B. Fundamental (Ground Tissue) * Used in the production and storage of food and in the support of plant.
B.1. Parenchyma * Parenchyma on leaves function for photosynthesis * Mechanical strength by maintaining turgidity and also store waste products.
B.2. Collenchyma * Support of stems and adapt themselves to the rapid elongation of leaves.
B.3. Sclerenchyma * Provides elasticity, flexibility, and rigidity to the plant body forming support.
PERMANENT TISSUE
C. Vascular Tissue C.1. Xylem Primarily functions for the transport of water and dissolved substances upward in the plant body. C.2. Phloem Primary functions in the transport of organic materials such as carbohydrates and amino acids.
ANIMAL TISSUES
Animal Tissues
Developed from the primary germ layers of the embryo:
Ectoderm Mesoderm Endoderm There are 4 types of
