BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists

used to stain structures containing starch which is indicated by the color change from brown to reddish-brown or blue-black. The stem‚ leaf‚ and root cross sections all contain starch. The roots stained the darkest meaning starch is stored more in them. Sudan IV dye stains lipids into pink to red color. All cells in a plant tissue contain lipids so the stem‚ leaf‚ and root cross sections are expected to stain red. However‚ only the stem cross section was able to produce a positive result.

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic
