Types of tissues:. TYPES OF TISSUES:. 1. Epithelial, nervous, muscle, connective. 2. Connective tissue: . . a. Contains few cells- spaced apart. . b. Defensive (type)- defends the body. ex. WBC. SWBAT determine the correct order of the levels of organization for structure and function, including . cells.  . tissues .  . organs.  . organ systems.  . whole organisms.  . ecosystems. Baseline (Flightpath D): . To be able to recognize examples of plant organs, state their functions and use a light microscope to view a cross-section of a leaf. State the functions of different plant tissues. (C) Stem cells. (A) Somatic cells. (B) Differentiation in cells. (D) . Germline. cells. (E) Uses of stem cells. (F) Cancer Cells. Human Cells. Division and differentiation in human . cells . (a). State the 4 main tissue types. Tissues. Biozone. p88 – 89. Biozone. p91 - 92. Lesson intentions:. Revise size relationships of structures.. Revise reasons for and functions of specialised cells.. Revise levels of organisation.. How do cells, tissues, organs, and organ systems explain the complexity of living things?. Essential. Question:. Turn to a seat partner and discuss the characteristics of living things. .. Let’s Review. Connect body parts, widely distributed. Functions. Protect, Support, Bind. Characteristics. Varied blood supply. Contain an extracellular matrix. Extracellular Matrix. Produced by connective tissues. Tissues – groups of similar cells performing a similar function. Organs – multiple tissues working together to perform a function. Scientists are researching ways to regenerate more than 30 different tissues and organs. 4 MAJOR TISSUE TYPES. Epithelial . (protection). . Connective . (bind organs). . Muscle. (movement). . Nerve . (communication). EPITHELIAL TISSUE. Protective coverings. Secretion. Absorption. organs. Literally, histology means tissue or web. To study tissues, certain techniques an instruments are used to study tissues. Tissue Preparation. For conventional bright field light microscopy, we follow the following steps:. DR. AYSER HAMEED. LEC.5. Tissue repair is critically influenced by the intrinsic proliferative capacity of the constituent cells. Based on this criterion, the tissues of the body are divided into three groups:. Fitua. Al-. Saedi. The . human . body is composed of four main types . of . tissues . :. . 1. . Epithelial . tissues . 2. . Connective . tissues. 3. Muscular . tissues. 4. . Nervous . tissues. A.  . . Tissues have two interacting components:. Cells .. . Extracellular matrix (ECM).which is consist of many kinds of macromolecules.. The (ECM) function :. Supports the cells and the fluids that transports nutrients to the cells .. complex.. Primary . structure of dicot stem, root and . leaf.. Secondary . thickening in dicot stem.. Unit - III . (Plant Anatomy). . Plants are stationary or fixed – they don’t move. Most of the tissues they have are supportive, which provides them with structural strength..
