Biology:cells
| Question | Answer |
|---|---|
| The region of the cell that is inside the cell membrane and includes fluid,the cytoskeleton,and all of the organelles except the nucleus | cytoplasm |
| The cells outer boundary | the cell membrane or plasma membrane |
| The membrane bound organelle control center for the cells DNA | nucleus |
| Most of the functions of a eukaryotic cell is controlled by | the cells nucleus |
| The shape of the nucleus is able to be maintained due to the help of a protein skeleton called | the nuclear matrix |
| Prokaryotes are different from eukaryotes because prokaryotes | lack a membrane bound nucleus and membrane bound organelles |
| Eukaryotes are different from prokaryotes because eukaryotes | have a nucleus and membrane-bound organelles |
| Well defined,intracellular bodies that perform specific functions for the cell are | organelles |
| A group of similar cells and their products that carry out a specific function is called | tissue |
| Groups of tissues that perform a particular job in an organism are called | organs |
| The first person to observe living cells was | dutch trader Anton Van Leeuwenhoek |
| The smallest unit that can carry life | cell |
| The man who studied nature using an early light microscope | Robert Hooke |
| The three parts of the cell theory are | all things are comprosed of one or more cells,cells are the basic unit and structure and function of an organism,cells come only from the reproduction of existing cells |
| Have a polar side and a non-polar side | phospholipids |
| Allows only certain molecules to enter and exit the cell | phospholipids |
| Structures in the nucleus made of DNA and protein | chromosomes |
| Organelles made of protein and RNA that direct protein synthesis in the cytoplasm | ribosomes |
| Transfers energy from organic molecules to ATP | mitochondria |
| Intracellular highway for molecules to move from one part of the cell to another | endoplasmic reticulum |
| Network of thin tubes and filaments | cytoskeleton |
