Protoplasm- | the basic substance of all life |
Cell- | the basic unit of structure and function in all living things |
Cell Membrane- | the outer protective covering of the cell |
Cytoplasm- | a semi-fluid inside the cell |
Organelles- | cell structure that may help a cell to function; located in the cytoplasm |
Nucleus- | a mass in the cytoplasm that may control many of the cells activities and is important in cell division |
Nucleolus- | located inside the nucleus and importatnt in cell reproduction |
Chromatin- | located in the cytoplasm and near the nucleus; contains two centrioles that seperate during mitosis |
Mitochondrain- | rod shaped or organelles located throughout the cytoplasm |
Golgi Apparcitus- | stack of membrane layers located in the cytoplasm |
Endoplasmic Reticulum- | a fine network of tubular structures located in the cytoplasm |
Lysosomes- | oval or round bodies found throughout the cytoplasm |
Pinotic Vesticles- | pocket-like folds in the cell membrane |
Mitosis- | a form of asexual reproduction |
Meisosis- | when sex cells divide by a process |
Tissue- | when cells of the same type join together for a common purpose |
Centrosome- | located in cytoplasm and near the nucleus; contains two centrioles that seperate during mitosis |
Dehydration- | an insufficient amount of tissue fluid |
Edema- | swelling of the tissue due to excess tissue fluids |
Epitheliol Tissue- | tissue that covers the surface of the body and is the main tissue of the skin |
Connective Tissue- | the supporting fabric of organs and other body parts; soft and hard |
Nerve Tissue- | controls and coordinates body activities by transmitting messages throughout the body |
Muscle Tissue- | produces power and movement by contraction of muscle fibers |
Organ- | two or more tissues joined together to perform a specific function |
System- | organs and other body parts joined together to perform a particular function |
Vacuole- | a membrane-boind cavity within a cell, often containing a watery liquid or secretion |
