Exercise No. 4
Plant and Animal Tissues I. Objectives:
Plant Tissues a. Illustrate, describe, and differentiate the various types of tissues characteristic of vascular plants b. Illustrate and describe how tissues are organized in the regions of the plant organ c. Recognize variations of each of the different tissues in different organs
Animal Tissues a. Illustrate, describe, and differentiate the different types of animal tissues b. Illustrate and describe the organization of different tissues in an animal organ c. Identify the tissues that compromise the anatomical plan of animals in cross section
II. Materials:
Plant Tissues
· Laboratory knife · Distilled water · Microscope · Slide of the longitudinal section of the root tip of Zea mays · Leaf of Rhoeo spathacea · Slide of a cross section of the leaf of Ixora sp. · Cross section of the stem of Cucurbita sp. · Cross section of the stem of Helianthus · Cross section of Zea mays stem Animal Tissues · A section of the ciliated epithelium (frog’s small intestine, frog’s ciliated epithelium, cheek cells · Blood smear · Slide of an adipose tissue · Slide containing a hyaline cartilage and elastic cartilage · Cross section of bone · Prepared slide of skeletal, smooth, and cardiac muscle · Nerve cell smear · Microscope
III. Procedure: Plant Tissues A. Meristematic Tissue 1. Obtain a slide of the longitudinal section of the root tip of Zea mays. 2. Focus the specimen under the scanner. 3. Draw the specimen. Include a brief description. B. Dermal Tissue 1. Obtain a leaf of Rhoeo spathacea. 2. Prepare an epidermal tissue wet mount by peeling off a portion of the upper epidermis. 3. Examine the tissue under the HPO. 4. Draw the epidermal cells. Include a brief
