Biology I-Cells Structure and Function Vocab: centriole cilia cell wall chloroplast cytoplasm endoplasmic reticulum flagella Golgi body Lysosome Mitochondria Nucleus plasma membrane Ribosome vacuoles 1. ___________________________ are membrane-bound spaces in the cytoplasm of cells used for the temporary storage of materials. 2. A ___________________________ in animal cells is a pair of small cylindrical structures composed of microtubules that only form during cell division and aid in the dividing of the cell. 3. The ___________________________ is an organelle in eukaryotic cells with a series of highly folded membranes surrounded in cytoplasm. 4. The ___________________________ in eukaryotic cells is the central membranebound organelle that manages cellular functions and contains DNA. 5. The ___________________________ is an organelle in eukaryotic cells with a system of flattened tubular membranes; sorts and packs proteins and sends them to their appropriate destinations. 6. A ___________________________ is a eukaryotic membrane-bound organelle that transforms energy stored in food molecules; has a highly folded inner membrane that produces energy-storing molecules. 7. ___________________________ are short, numerous, hair-like projections composed of pairs of microtubules; frequently aid in locomotion. 8. ___________________________ are long projections composed of microtubules; found on some cell surfaces they help propel cells and organisms by a whip-like motion. 9. A ___________________________ is a nonmembrane-bound organelle in the nucleus where proteins are assembled. 10. A ___________________________ is a chlorophyll-containing organelle found in the cells of green plants and some protists; capture light and convert it into chemical energy. 11. A ___________________________ is responsible for digesting cell parts and foreign substances 12. The ___________________________ is a phospholipid bilayer that separates the inside of the cell from its outer environment. 13. ___________________________ is a clear gelatinous fluid in cells that is the site of numerous chemical reactions; in eukaryotic it suspends the cell’s organelles. 14. The ___________________________ is a fairly rigid structure located outside the plasma membrane of plants, fungi, most bacteria, and some protists; provides support and protection. eukaryote Multicellular Organ organ system organelle organism prokaryote Tissue Unicellular 1. An ___________________________ is anything that possesses all the characteristics of life; has an orderly structure, produces offspring, grows, develops, and adjusts to changes in the environment. 2. A ___________________________ is a unicellular organism such as bacteria which is composed of a prokaryotic cell that lack internal membrane-bound structures. 3. ___________________________ means having or consisting of many cells. 4. ___________________________ means having or consisting of a single cell. 5. ___________________________ is a group of cells that work together to perform a specific function. 6. An ___________________________ is a group of two or more tissues organized to perform complex activities within an organism. 7. A ___________________________ is a unicellular or multicellular organism composed of eukaryotic cells which contain a true nucleus and membrane-bound organelles. 8. An ___________________________ is a membrane-bound structure with particular functions within eukaryotic cells. 9. An ___________________________ is made up of multiple organs that work together to perform a specific life function.
