| Where does photosynthesis take place? | chloroplast |
| Where does protein synthesis take place? | ribosomes |
| What is the storage area for pigments and nutrients called? | vacuoles |
| Where is the genetic material stored? | nucleus |
| Where does ATP synthesis occure? | Mitochondrion |
| This is only found in pants and bacteria. | cell wall |
| What is refered to as the interconnected membrane channels? | endoplasmic reticulum |
| What part of the cell sorts and packages material? | golgi apparatus |
| Where does the toxin neutralization take place? | peroxisome |
| What is Osmosis? | the movement of water across a membrane |
| Having a cell wall affects the process of | osmosis |
| Depending on the concentration of solute molecules, this will effect the process of _______ ? | osmosis |
| What can grow and reproduct on their own without a living host? | bateria |
| What are the reproducing phases for bacterium in the optimum (the best) conditions? | lag, log, stationary, death |
| How do molecules disperse? | in a random fashion and from a more concentrated area to a less consentrated area |
| Bacteria cell is a ____ ? | prokaryoke |
| The degree of disorder in a system is called _______ ? | Entrophy |
| A gradul decrease in permeability of a membrane is called the what? | concentration gradient |
| In the nucleus of eukaryotic cells the genetic material is organized into? | chromosomes |
| What is the main function of the plasma membrane ? | regulates passage of material in and out of the cell |
| The plasma membrane acts as the boundry or border for the _____? | cytoplasma |
| The plasma membrane functions in the recognition of ______? | self |
| What is the difference between active transport (AT) and Diffusion (D)? | active transport requires energy; Diffusion does not |
| Viruses are | unable to reproduct on their own |
| What are bigger viruses or bacteria? | bacteria |
| What has a protective coat, bacteria or virus? | viruses |
| What are made up of either DNA or RND, viruses or bacteria? | viruses |
| Whatis active transport? | moving materials in an opposite direction against a concentration |
| What is diffusion? | a process where molecules spread away from areas of high to low concentration |
| What is osmosis? | the diffusion of water across a membrane |
| Who has a protective coat, bacteria or virus? | viruses |
| Who invades cells, injects there DNA or RNA in to them so that they cells reproduce it? | viruses |
| What do they think were the 1st on Earth? | bacterium |
| Who has cirled shaped DNA ? | bacterium |
| Who has no membrane around its nucleus? | bacterium |
| What is the endosymbiotic theory? | one prokaryotic cell engulfed anothe on e and decided it could be useful and benificial so it used it and the tow became as one thus creating one cell with two parts |
| What does "iso" mean? | same |
| What does "hyper" mean? | more |
| What does "Hypo" mean? | less |
| What is isotonic solutins? | when the concentration of solute is equal on both sides and water moves back and forth |
| What is hypertonic solutions? | when there is more salt solute molecules outside the cell. it will cause water to be sucked in that direction |
| Whatis hypotonic solutions? | when there is less salt solute molecules outside the cell, water is moved inside the cell |
| What is doyou know about salt? | salt sucks |
