1: Cell | Discovered by Robert Hooke in 1665 the cell is defined as,the smallest organizational unit of a centralized group or movement.
2: Animal Cells | Animal cells are all built to the same basic pattern. The nucleus is a membrane-bounded sac containing the genetic material of the cell. The genetic information is coded for in DNA (deoxyribonucleic acid). The nuclear membrane is perforated by pores that are important in controlling the exchange of substances between the nucleus and cytoplasm.
4: Plant Cells | The basic unit of structure and function in nearly all plants. Although plant cells are variously modified in structure and function, they have many common features. The most distinctive feature of all plant cells is the rigid cell wall, which is absent in animal cells.
6: Bacterial Cells | Extremely small, relatively simple prokaryotic microorganisms traditionally classified with the fungi as Schizomycetes.
8: Mitochondrion A spherical or elongated organelle in the cytoplasm of nearly all eukaryotic cells, containing genetic material and many enzymes important for cell metabolism, including those responsible for the conversion of food to usable energy. Also called chondriosome.
10: Nucleus A central or essential part around which other parts are gathered or grouped
12: DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms with the exception of some viruses.
14: Chromosomes | A circular strand of DNA in bacteria that contains the hereditary information necessary for cell life.
16: Cell membrane- The semipermeable membrane that encloses the cytoplasm of a cell.
18: Cell Wall- The definite boundary or wall that is part of the outer structure of certain cells.
20: Flagella- A long lashlike apendage serving as an organ of locomotion in protozoa
22: Cilia- Minute hairlike structure, identical in structure to flagella, that line the surfaces of certain cells and beat in rhythmic waves, providing locomotion.
24: chloroplast- An organelle that contains the green coloring matter of leaves and plants essential to photosynthesis.
26: Centriole- A small,cylindrical cell organelle, seen near the nucleus in the cytoplasm, that divides during mitosis and move to opposite poles of the cell.
28: Endoplasmic Reticulum- A network of tubular membranes within the cytoplasm that transports materials throughout the cell.
30: Vacuole- A membrane-bound cavity within a cell, often containing a watery liquid or secretion.
32: Cytoskeleton- A shifting lattice arrangement of structural and contractile components disturbed throughout the cytoplasm functioning as structural support and transportation.
34: Lysosomes- An organelle containing enzymes that digest particles and that disintegrate the cell after its death.
36: Golgi Apparattus- An organelle, consisting of layers of flattened sacs, that takes up and processes secretory and synthetic products from the endoplasmic reticulum that moves secretions where they need to be.
38: Ribosomes- An organelle occurring frequently in the cytoplasm in small clusters and manufactures protein.
