| One part of the cell theory is... | all cells arise only from living cells |
| One part of the cell theory is... | cells are the units of structure of all living things |
| One part of the cell theory is... | cells are the units of function of all living things |
| The term cell was first used by | Hooke |
| Structures outside of the cell nucleus that contain genetic material are | mitochondria and chloroplasts |
| Most cell activities are controlled by the | nucleus |
| Which cell structure is considered to be nonliving? | glogi complex |
| Structures found in animal cells but not generally in plant cells are | centrioles |
| The enzymes of aerobic cellular respiration are mainly in | the mitochondria |
| The contents of a cell can be chemically different from the surrounding medium because | the cell membrane is semipermeable |
| Damaged or old cell parts are destroyed by digestive enzymes in the | lysosomes |
| The system of membrane-lined channels involved in the production and transport of materials in the cell is the | endoplasmic reticulum |
| The organelles whose main function is during cell division are | centrioles |
| Ribosomes are produced in | nucleoli |
| The membranes of the endoplasmic reticulum may be lined with | ribosomes |
| The packaging and secretion of cell products involves | the golgi complex |
| Which structure performs a similar function in both plant and animal cells? | ribosomes |
| The modern cell theory fails to account for | viruses |
| Which structue is a boundary between the living cell and its environment? | cell membrane |
| Which structure carries out a similar function in both pland and animal cells? | plasma membrane |
| Which are the main structural components of a cell membrane? | proteins and lipids |
| An organelle differs from an organ in that an organelle | is a substructure of a cell |
| Which is the site directly involved in protein synthesis | ribosome |
| Which cell structure is nonliving?endoplamic recticulum, chloroplast, cell wall, centrosome | cell wall |
| What is common to most plant and animal cells | cytoplasm and cell membrane |
| Which cellular structures are found in the epidermal cells of humans but not in the epidermal cells of leaves? | centrioles |
| The eribosome is an organelle that functions in the process of | protein synthesis |
| Which organelles can be ovsaerved only with the aid of an electrom microscope? | ribosomes |
| Intracellular transport of materials is most closely associated with which cell organelle? | endoplasmic reticulum |
| Some sicentintist disagree on whether or not viruses are alive. A major reason for this disagreement is that viruses | are not composed of units of structure known as cells |
| Enzyme synthesis in a living cell occurs at which cytoplasmic organelles? | ribosomes |
| Which cell organelle is involved most directly in the digestion of large particles brounge into a cell's vacuole? | lysosome |
| The nucleus includes... | nucleolus, chromosomes, genes |
| An organelle found in most plant cells, but absent from animal cells, is the | chloroplast |
| In which organelles are enzymes for intracellular digestion stored? | lysosomes |
| Most cellular respiration in plants takes place in organelles known as | mitochondria |
| Pathways for the transport of materials within a living cell are provided by the | endoplasmic reticulum |
| Which organelle contains hereditary factors and controls most cell activities? | nucleus |
| Centrioles are cell structures involved primarily in | cell division |
