PLAY
cell (plasma)
composed of protein and phospholipid molecules,provides form to cell and controls passage of materials into and and out of cell.
cell wall
cellulose fibrilis, provides structure and reigidity to plant cell.
cytoplasm
fluid to jelly-like substance, suspending medium of organelles.
endoplasmic reticulum
interconnecting hollow channels, supporting framework of cell; cell transport.
ribosomes
granules of nucleic acid
mitocondria
double layered sacs with cristae, production of ATP
Golgi apparatus
Flattened sacs with vacuoles, synthesizes carbohydrates and packages molecules for secretion.
Lysosomes
membrane-surronded sacs of enzymes, digests foreign molecules and worn cells.
Centrosome
mass of two rod-like centrioles, organizes spindle fibers and assists mitosis.
Vacuoles
membrane sacs, stores and excretes substances with the cytoplasm.
Fibrils and microtubles
protein strands, supports cytoplam and transports materials.
Cilia and flagella
cytopasmic extensions form cell, movement of particles along cell surface or move cell.
Nucleus
Nuclear membrane, nucleolus, and chromatin (DNA), direct cell activity; form ribosomes.
Chloroplast
Inner (grans) membrane within outer membrane, photosynthesis.
