PPT-Chapter 3: Fundamental Cells and Tissues

Cells In the late 1600s British born Robert Hooke coined the term cell to describe the basic unit of life Where did the term cell come from In 1665 Robert Hooke inspected thin slices of cork and found that they consisted of millions of small irregular units. 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. Biology Department. Plant Tissues. Tissues can be classified into . :. Meristematic. tissues. . Permanent . tissues. I . . Meristematic. . tissues. They are usually called meristems. . They . are young tissues of the embryo or the mature plant which . Dr . Mahmood. S . Choudhery. , PhD. Assistant Professor. Advance Center of Research in Biomedical Sciences. Incharge.

The classification of tissue types is based on the structure of cells; the composition of noncellular substance surrounding cells (extracellular matrix) and the functions of the cells.. 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. 4-. 2. Tissue Level of Organization. The classification of tissue types is based on the structure of cells; the composition of noncellular substance surrounding cells (extracellular matrix) and the functions of the cells.. 4 MAJOR TISSUE TYPES. Epithelial . (protection). . Connective . (bind organs). . Muscle. (movement). . Nerve . (communication). EPITHELIAL TISSUE. Protective coverings. Secretion. Absorption. I. Introduction. . A. Introduction. A. Introduction. Cells . are organized into . layers or groups of similar cells with a common function called tissues. .. 2. Intercellular junctions connect . Cells are arranged in tissues that perform specialized structural and functional roles. Four Major Types of Tissue:. Epithelial. Connective. Muscle. Nervous. Introduction. General Characteristics.

By the process of photosynthesis, plants naturally remove carbon from the. a. tmosphere and incorporate it into their tissues. Carbon that is locked in . m. olecules of wood and other durable plant tissues can stay out of the. . 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 ..
