apologia plant cells
plant cell structure definitions
Term | Definition |
---|---|
cell wall | a structure that surrounds the cell membrane and provides support to the cell |
cytoplasm | the jelly-like fluid inside the cell - mostly water |
nucleus | a large organelle in a eukaryotic cell that contains the cell's DNA/chromosomes/genetic material |
ribosomes | non membrane-bounded organelles that are responsible for making proteins |
mitichondria | the organelles that break down food/sugar to release energy |
endoplasmic reticulum | rough ER transports proteins around the cell, and contains ribosomes; smooth ER acts as a pathway through the cell, and contains no ribosomes |
golgi bodies | the organelle that packages proteins and lipids before sending them through the cell; they also take part in secretion |
vacuole | the organelles that store waste, water and other materials |
chromoplasts | organelles that contain pigments (chlorophyll) used in photosynthesis |
centrioles | are involved in cellular reproduction/division |
middle lamella | thin film between cell walls of adjacent plant cells, made mostly of pectin |
lysosome | organelle in animal cells responsible for hydrolosis reactions that break down proteins, polysaccharides, disaccharides and some lipids |
leucoplasts | organelles that store the starches left over from photosynthesis |
cytoskeleton | network of fibers that holds the cell together and aids the cell in movement |
plasma membrane | semipermeable membrane between the cell's contents and either the cell wall or the cell's surroundings |
