Stem Cells-Intro
Cell Types and Cell Theory
Question | Answer |
---|---|
CELLS | THE MOST FUNDAMENTAL UNIT OF LIFE BECAUSE IT'S THE SMALLEST BIOLOGICAL ENTITY THAT CAN ACQUIRE AND PROCESS ENERGY, REPAIR, AND REPRODUCE INDEPENDENTLY |
THEORY | A MODEL OR EXPLANATION THAT IS CONSISTENT WITH ALL KNOWN RESULTS FROM REPLICATED EXPERIMENTS AND IS REFUTED BY NONE. |
THE CELL THEORY | CELLS ARE THE MOST FUNDAMENTAL UNIT OF LIFE. ALL SINGLE AND MULTI-CELLULAR SPECIES ARE COMPOSED OF CELLS. ALL CELLS ARE PRODUCED FROM PRE-EXISTING CELLS |
SINGLE CELL SPECIES | PROKARYOTES, EUKARYOTES, ALGAE |
MULTI-CELL SPECIES | CONSIST OF MANY CELL TYPES EACH PERFORMING A UNIQUE SET OF FUNCTIONS THAT MUST INTERACT IN ORDER TO GROW, DEVELOP, DEFEND, MAINTAIN, REPAIR, REPRODUCE A FULLY FUNCTIONAL ORGANISM |
TYPES OF CELLS | GLAND, REPRODUCTIVE, NERVE (GRN BBM) BONE, BLOOD, MUSCLE |
NUMBER OF CELL TYPES IN THE HUMAN BODY | 220 TYPES & 50 TRILLION TOTAL |
PROKARYOTES | CONTAIN PROTEIN SHELLED MICRO COMPARTMENTS OF A UNIQUE SET OF ENZYMES THAT PERFORMS A UNIQUE SPECIALIZED BIOLOGICAL FUNCTION. TYPES ARCHAEA & BACTERIA SHAPES: HELICAL, BACILLI, COCCI |
EUKARYOTES | EACH ORGANELL IS A MEMBRANE ENCLOSED COMPARTMENT THAT PERFORMS A SPECIALIZED BIOCHEMICAL FUNCTION. TYPES (F-PAP) FUNGI, PLANT, ANIMAL, PROTIST |
CYTOPLASM | PART OF THE EUKARYOTIC CELL BETWEEN THE PLASMA AND THE NUCLEUS |
CYTOSOL | SEMI-FLUID PART OF THE CYTOPLASM BETWEEN THE ORGANELLS IN A EUKARYOTIC CELL |
TISSUE | A GROUP OF CELL ORGANIZED INTO A FUNCTIONAL UNIT. TYPES; SIMPLE AND COMPLEX |
4 TYPES OF ANIMAL TISSUE | (C-MEN) CONNECTIVE, MUSCLE, EPITHELIAL, NERVOUS |
EPITHELIAL TISSUE | CELLS WITH LARGE CYTOPLASMIC VOLUMES FUNCTIONS OF SECRETION OR ABSORPTION -COVERS EXPOSED IN/EXTERNAL SURFACES -SENSORY FUNCTIONS -PATHOGEN DETECTION -GAS DIFFUSION -ABSORPTION/SECRETION -MOV'T OF TRAPPED PARTICLES IN RESP. TRACT |
CONNECTIVE TISSUE | TRANSPORTS, STORES, CUSHIONS, ORGANIZES TISSUE AND HOLD ORGANS IN PLACE. BINDS CELLS TOGETHER AND PROVIDES STRUCTURAL SUPPORT |
MUSCLE TISSUE | PROVIDES MOV'T SKELETAL, SMOOTH, CARDIAC |
NERVOUS TISSUE | SENSORY, COMMUNICATION, REGULATION AND COORDINATION, CAPTURES, INTEGRATES 7 PROCESS INFO, DECISION MAKING, COGNITION AND CREATIVITY. EX GLIAL CELLS |
3 PLANT TISSUE TYPES | DERMAL, GROUND, VASCULAR (dgv) |
DERMAL TISSUE | COVERS ALL OUTER PLANT SURFACES. -GAS EXCHANGE -SECRETION -WATER PROOFING -ABSORPTION -PHYSICAL BARRIER -SUPPORTS LEAVES |
GROUND TISSUE | THIS PLANT TISSUE TYPE PROVIDES STORAGE, PHOTOSYNTHESIS, STRUCTURAL SUPPORT |
VASCULAR TISSUE | THIS PLANT TISSUE PROVIDES STORAGE, TRANSPORT, AND STRUCTURAL SUPPORT |
