Come from the Greek term pro meaning "before" and karyon meaning "kernel" referring to the nucleus. - Prokaryotes, Have no nucleus, DNA is in the nucleoid. - Prokaryotes, Make up the most prokaryotes - Bacteria, Found in extreme environments such as hot springs or near volcanoes. - Archaea, Thicker cell wall - Archaea, Permeable cell wall - Bacteria, Bacteria and Archaea ad what kind of organisms? - Unicellular organism, Roles of prokaryote - 1. Decomposing dead organisms 2. Digestion of difficult to break down carbohydrates, Lacks a nucleus, or any membrane bound organelle - Prokaryotic cell, Eu meaning "true" and karyon meaning "kernel" - Eukaryotes, Little organ - Organelles, Has a membrane bound nucleus and other membrane bound compartments or sacs, called organelles. - Cell, Major organelles in a eukaryotic cell? - Cell membrane, cell wall, ribosomes, nucleus, mitochondria, endoplasmic reticulum, lysosomes, What kind of organism is a eukaryotic cell? - Unicellular and Multicellular, What are the four kingdoms of eukaryotic organisms> - 1. Kingdom Plantae 2. Animalia 3. Fungi 4. Protists, Photosynthetic organisms containing cell walls and specialized reproductive tissues. - Plants, Lack cell walls, capable of locomotion, have a digestive tract. - Animals, Digests their food externally and then absorb it though their cell walls. - Fungi, What kind of organism are plants, animals, and fungi? - Multicellular organism, What kind of organism is a protist? - single celled, photosynthetic or heterotrophic, Sessile means? - Non-mobile, Commonly seen outside as coverings or as lining of organs and cavities. - Epithelial tissue, For secretion - Cuboidal, Serves as barriers for pathogens, mechanical injuries, and fluid loss - Epithelial tissue, Brick shaped cells; secretion and active absoption - Simple columnar, Plate like cells; exchange of material through diffusion - Simple squamous, Multilayered and regenerates quickly for protection - Stratified squamous, Single layer of cells; varying height; lining of respiratory tract, usually lined with cilia. - Pseudo-stratified columnar, made up of plasma - Blood, Euthrocytes carry what? - Oxygen (RBC), Leukocytes carry what? - Defense (WBC), platelets function? - Blood clotting, made up of loose connective tissue that is found in the skin - Connective Tissue Proper, Connective tissue made up of collagenous fibers found in tendons and ligaments - Fibrous connective tissue, Tissue that stores fats to insulate the body and store energy - Adipose tissue, Characterized by collagenous fibers embedded in chondroitin sulfate - Cartilage, Functions as cushions between bones - Cartilage, Secretes collagen and chondroitin sulfate - Chondrocytes, Connective tissue made by osteoblasts - Bone, Composed of long cells that allow the body to move voluntary or involuntary  - Muscle tissue, What are muscle tissues composed of? - Muscle fibers, Embryonic development is a process called? - Myogenesis, Voluntary movements - Striated, Striated, attached to the skeleton - Skeletal, Striated with intercalated disk for synchronized heart contraction, located in the walls of the heart - Cardiac, not striated; located in walls of hollow visceral organs - Smooth, Composed of nerve cells called neurons and glial cells that function as support cells - Nervous tissue,
