|
Definition
1. All organisms are composed of one or more cells.
2. the cell is the basic unit of structure and organization of all organisms.
3. All cells come from pre-existing cells. |

| Characteristics of Prokaryote cells? |
|
Definition
Mostly Unicellular
No true nucleus
Lack membrane-bound organelles
EX: Bacteria |
|
|
Term
| Characteristics of Eukaryote cells? |
|
Definition
Membrane-bound organelles
Usually Multicellular
(Very few are unicellular) |
|
|
Term
| What is a plasma membrane? |
|
Definition
It surrounds the cell
Gateway throug which materials enter and exit the cell.
Composed of 2 layers of lipids. |
|
|
Term
|
Definition
| Composed of 1 glycerol and 3 fatty acid chains. |
|
|
Term
|
Definition
Strands of genetic material
Contains directions for making protiens |
|
|
Term
|
Definition
Make ribosomes
found in the nucleus |
|
|
Term
|
Definition
Not membrane-bound
made or RNA and protein
The site where the protiens are made
leave the nucleus and enter the cytoplasm through pores in the nuclear envelope |
|
|
Term
|
Definition
| clear, gelatinous fluid inside a cell |
|
|
Term
|
Definition
1. Smooth- no ribosomes attatched
-production and storage of lipids
2. Rough- has ribosomes attatched
-site where chemical reactions occur in the cell
-After the proteins are made by the ribosomes, they are transferred to the Golgi Apparatus |
|
|
Term
|
Definition
1. Sorts proteins into "packages"
2. Packs the sorted proteins into vesicles in which they are sent to the appropriate location within the cell. |
|
|
Term
|
Definition
1. Membrane-bound compartment or sack a cell uses for temporary storage of food, enzymes, or other materials needed by the cell
2. usually just one large vacuole in plant cells.
3. Not usually present in animal cells
4. Sometimes used for waste storage. |
|
|
Term
|
Definition
1. Organelles containing digestive enzymes
2. Digest worn out organelles, food particles, engulfed viruses or bacteriai, or even the cell which contains them if no longer needed. |
|
|
Term
|
Definition
1. In plant cells
2. capture light energy and convert it to chemical energy
3. Double membraned |
|
|
Term
|
Definition
1. Inner membrane of chloroplasts
2.Energy from light is trapped here. |
|
|

|
Term
|
Definition
Traps light energy in plant cells
2. Gives leaves and stems their green color |
|
|
Term
|
Definition
in plant and animal cells
2. transform energy for the cell
3. Double membraned organelle |
|
|
Term
|
Definition
1. Inside cells in the cytoplasm
2. Act as a support structure
3. Not rigid ; can change shape, thus changing the cells shape
4. Composed of microtubules and microfilaments |
|
|
Term
| Microtubules and microfilaments |
|
Definition
Microtubules and microfilaments anchor and support many organelles inside the cell in addition to providing support and shape to the cell
2. "highway system through which materials move within the cell" |
|
|
Term
|
Definition
1. found in animal cells and most protist cells.
2. made up of microtubules
3. occur in pairs
4. play an important role in cell division |
|
|
Term
|
Definition
Many of them
2. made of microtubuels
3. aid cell in feeding and locomotion |
|
|
Term
|
Definition
1. Usually just 1 or 2, longer than cillia
2. made of microtubuels
3. aid cell in feeding and locomotion |
|
|
Term
| similarites between plant and animal cells |
|
Definition
| Similarities-Animal and plant cells aer both ekaryotic: that means tat they have proper nucleii. Every animal and plant cell has a nucleu which contains chromosones. The nuclear envelope surrounding the nucleus speparatesthe chromosomes from the cytoplasm. they booth have a cell membrane aroudn them. Cell membranes are very thin, nevertheless they are able to control what can get in or out of a cell. They both ahve a proper nucleus cytoplasm, and a cell membrane. |

| differences between plant and animal cells |
|
Definition
| Differences-Plant cells are surrounded by a cell wall made of cellulose...Plants cells aren't. WHEN PLANT CELLS ARE PUT IN DISTILLED WATER THEY START TO SWEEL UP, BUT dont burst. ANIMAL CELLS DO. PLANAT CELLS CONTAIN chloroplasts. Most of the space inside a plant cell is filled with cell sap in a large vaucuole. Animal cells never contain large vacuoles. Plant cells usually have a very regular shape, and animal cells have very irregular shapes. |

Term
| Differences between prokaryotic and eukaryotic cells? |
|
Definition
Eukaryotes= Animal & Plant Cells.
Both have single celled and multi cellular animals and plants calledeukaryotes. their cells contain proper nucleii with chromosones.
Prokaryotes-Their cells DO NOT have proper nuclei. They have a circular molecule of DNA which contains all their genetic info. |
