Chapter 7 Cells Flashcards
Cell
The basic unit of structure and function in all living things
Anatomy
The study of the form and structure of an organism
Cell membrane
The outer , protective covering of cell
Centrosome
Organelle located in the cytoplasm; helps cell division by creating an even division of the chromosomes
Chromatin
Located inside the nucleus; made of DNA and protein.
Connective tissue
The supporting structure of organs and other body parts
Cytoplasm
A semi-fluid inside the cell but outside the nucleus; organelles are found in the cytoplasm
Dehydration
Insufficient amount of tissue fluid
Edema
An excessive amount of fluid; causes swelling of the tissues
Endoplasmic reticulum
A fine network of tubular structure located in the transport of materials in/out of the nucleus; aids storage/synthesis of materials
Epithelial tissue
Covers the surface of the body & the main tissue of the skin (largest organ)
Genes
Unit of heredity transfer from parents to offspring; determines some characteristics of the offspring
Genome
The total mass of genetic instruction that humans Inherit from parents.
Golgi apparatus
A sac of membrane layers located in the cytoplasm: produces,stores and packages secretions for discharge from the cell,
Lysosomes
The round bodies found throughout the cytoplasm that contain digestive enzymes “suicide sacs”
Meiosis
The process where sex cells divde
Mitochondria
Rod-shaped organelles located throughout the cytoplasm; break down carbohydrates, proteins and fats to produce ATP =energy source for the cell.
