Cell Structure Vocab
Term | Definition |
---|---|
Cell Theory (3 Concepts) | 1. All organisms are made up of cells 2. All existing cells are produced by other living cells 3. The cell is the most basic unit of life |
Cytoplasm | is a jellylike substance that contains dissolved molecular building blocks such as proteins, nucleic acids, minerals and ions |
Organelle | which are structures specialized to preform distinct processes within a cell |
Prokaryotic Cell | do not have a nucleus or other membrane-bound organelles |
Eukaryotic Cell | have a nucleus and other membrane-bound organelles |
Tell Three Ways in Which Prokaryotic Cells Differ From Eukaryotic Cells | 1. Smaller 2. Simple 3. Circular free dna |
Cytoskeleton | is a flexible network pf proteins that provide structural support for the cell |
Nucleus | is the storehouse for most of the genetic information or dna in your cells |
Endoplasmic Reticulum | or the ER, is an interconnected network of thin, folded membranes |
Ribosome | are tiny organelles that link amino acids together to form proteins |
Golgi Apparatus | consists of closely layered stacks of membrane-enclosed spaces that process, sort and deliver proteins |
Vesicle | membrane-bound sacs that divide some materials from the rest of the cytoplasm and transport these materials from place within a cell |
Mitochondrion | supply of energy to the cell |
Vacuole | is a fluid-filled sac used for the storage of materials needed by a cell |
Lysosome | are membrane-bound organelles that contain enzymes |
Centriole | are cylinder shaped organelles made o short microtubules arranged in a circle |
Cell Wall | which is rigid layer that gives protection, support and shape of the cell |
Chloroplast | organelles that carry out photosynthesis a series of complex chemical reactions that convert solar energy into energy-rich molecules the cell can use |
Cell Membrane | forms a boundary between a cell and the outside environment and controls the passage of materials into and out of a cell |
