Science Notes Cells

we have a test on our cell notes in Mr. Tyler's class.

QuestionAnswer
Cells basic unit of structure and function in living things
Structure what an organism is made of and how it is put together
Function processes that enable an organism to stay alive and reproduce
Cell Theory all living things are made of cells cells are the basic unit of structure and function in living things all cells are produced from other cells
Compound microscope two lenses, one lens magnifies the other lens’ magnification (convex lens)
Resolution sharpness of an image
Electrons microscope uses a beam of electrons instead of light to produce a magnified image
Organelles tiny cell structures that carry out specific functions
Cell Membrane controls what substances go in and out of the cells
Nucleus control center of the cell
Nuclear Envelope membrane that protects the nucleus
Chromatin made up of DNA, lives inside the nucleus, the “blueprint” for what the cells are doing. Strands that contain genetic materials that instructs the cell how to grow
Nucleolus making ribosomes and protein. Where ribosomes are made.
Cytoplasm clear, thick, gel-like substance between cell membrane and nucleus
Mitochondria converting energy in food molecules to energy the cell can use. Known as “powerhouses” of cells.
Endoplasmic Reticulum the passageways carry proteins and other materials from one part of the cell to another
Ribosomes small grain-like bodies that produce protein
vacuole a large water filler sac, stores food and other materials
Golgi body receives proteins and other materials and redistributes them to other parts of the cell
Chloroplasts captures energy and sunlight and use it to produce food in plant cells, NOT animal cells.
