Label each level indicated in the diagram below. LEVELS OF ORGANIZATION LEVELS OF ORGANIZATION Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. SCIENCE, TECHNOLOGY, ENGINEERING AND MATHEMATICS GENERAL BIOLOGY 1: ANIMAL AND PLANT TISSUES MR. EDGARDO JR. VIADOR  OBJECTIVES: 1. Classify different cell types (plant and animal tissues) and specify the function(s) of each; and 2. Describe some cell modifications that lead to adaptation to carry out specialized functions KEY POINTS! Tissues is an aggregation of cells that function together and have a similar function. Tissues are adapted by the structure of their cells to carry on a particular function. Single-celled organisms are different from single cells that are part of an organism. PICTURE ANALYSIS Classify the ff. pictures as animal or plant tissues.

Dermal Tissue epidermal cells formed from the outermost surface of the leaves mediates most of the interactions between a plant and its environment stomata perforates the epidermis at certain places. The stomata help in loss of water and gaseous exchange. Epidermal cells secrete a waxy substance called cuticle, which coats, waterproofs, and protects the above- ground parts of plants preventing water loss, abrasions, infections, and damage from toxins. 1.1. Dermal Tissue 1.2. Ground Tissue makes up much of the interior of a plant and carries out basic metabolic functions involved in producing nutrients by photosynthesis and preserve nutrients Ground tissue in stems provides support and may store food or water. Ground tissues in roots may also store food. 1.3. Vascular Tissues transport water and dissolved substances inside the plant a. The xylem carries water and dissolved ions from the roots to stems and leaves. b. The phloem carries dissolved sugars from the leaves to all other parts of the plant. 1.3.
