Cellular Vocab
Vocab for cells
| Question | Answer |
|---|---|
| What are cells? | The basic units of life |
| What are the parts of the cell theory? | -All living things are composed of cells -Cells are the basic units of structure and function in living things -New cells are produced from existing cells |
| What is the nucleus? | A large membrane enclosed structure that contains the cell's genetic material in the form of DNA |
| What are eukaryotes? | Cells that contain nuclei |
| What are prokaryotes? | Cells that do not contain nuclei |
| What are organelles? | Organs of a cell, "little organs" |
| What is the cytoplasm? | The portion of the cell outside the nucleus |
| What is the nuclear envelope? | Two membranes that enclose the nucleus, while allowing materials to move in and out |
| What are chromatin? | DNA bound to protein |
| What are chromosomes? | Condensed chromation that passes genetics |
| What is a nucleolus? | Where the assembly of ribosomes begin, inside the nucleus |
| What are ribosomes? | Small Particles of RNA and protein found throughout the cytoplasm |
| What is the endoplasmic reticulum? | The site where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell |
| What is the golgi apparatus? | Modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion out side the cell |
| What are lysosomes? | Small organelles filled with enzymes |
| What are vacuoles? | Organelles that store material such as water, salt, proteins, and carbohydrates |
| What are mitochondrias? | Organelles that convert the chemical energy stored in food into compounds that are more convenient for the cells use |
| What are chloroplasts? | Organelles that capture energy from sunlight and convert it into chemical energy in a process called photosysthesis |
| What is an exoskeleton? | Eukaryotic cells are given their shape and internal organization by this supporting structure |
| What are centrioles? | Organelles located near the nucleus that help organize cell division |
| What is cell membrane? | A thin, flexible barrier that surrounds all cells |
| What is the cell wall? | A strong supporting layer around the cell membrane |
| What is a lipid bilayer? | The composition of nearly all cell membranes, all double layered sheet |
| What is concentration? | The mass of the solute in a given volume of solution, or mass/volume |
| What is diffusion? | When particles tend to move from an area Where they are more concentrated to an area where they are less concentrated |
| What is the equilibrium? | When the concentration of the solute is the same throughout the system |
| What is osmosis? | The diffusion of water through a selectively permeable membrane |
| When is something isotonic? | When the concentration of something is equal on both sides |
| What does hypertonic mean? | The more concentrated solution |
| What does hypotonic mean? | The less concentrated solution |
| What is facilitated diffusion? | When the cell membrane channels are said to facilitate, or help, the diffusion of glucose across the membrane |
| What is active transport? | When something is moved against the concentration in the opposite direction |
| What is endocytosis? | The process of taking material into the cell by means of infoldings of the cell membrane |
| What is phagocytosis? | Extensions of cytoplasm surround a particle and package it within a food vacuole |
| What is pinocytosis? | Tiny pockets form along the cell membrane, fill with liquid, and pinch off to form vacuoles |
| What is exocytosis? | The membrane of the cauole surrounding the material fuses with the cell membrane, forcing the contents out of the cell |
| What is cell specialization? | When cells throughout an organism can develop in different ways to perform different tasks |
| What is tissue? | A group of similar cells to perform a specific function |
| What is an organ? | A group of tissue working together to complete a specific function |
| What is an organ system? | A group of organs working together to complete a specific function |
