Who discovered the first cell |
Robert Hooke discovered the first cell in 1665 |
|
Theory of life |
"Every living thing is made of 1 or more cells" |
|
Semi-permeable |
Letting in good things, blocking other things (viruses) out. |
|
DNA |
Deoxi-ribo-nucleic-acid |
|
What kind of cells have a lot of mitochondria organelles |
Muscle cells or plant root cells |
|
Ribosome |
Ribosomes is a small organelle that attaches to the rough ER or floats around in the cytoplasm. Ribosomes help produce proteins |
|
What cells have a lot of ribosomes |
The liver cells or pancreas cells contain a lot of ribosomes. |
|
Endoplasmic Reticulum (ER) |
Highway inside cell. Transports proteins |
|
Golgi |
Packages proteins to use in cell or to transport out of cell |
|
Vesicles |
Sacs that arise from the golgi |
|
Lysosome |
Also known as 'suicide sacs', lysosomes have a kind of fluid that helps digest food and recycle old materials. When a cell wants to die these lysosomes break. |
|
Cilia |
Hairs alone single celled organisms used for transportation. |
|
Flagella |
Long tail used by single celled organisms for transportation |
|
Plastids |
Organs of colour found in plant cell |
|
Microtubules and microfiliments |
These form the cells skeleton and maintain the shape of the cell |
|
Chlorophyll |
Used for photosynthesis inside plant cells |
|
Cell wall |
Made of cellulose, the cell wall supports each individual cell, strengthening them. |
|
Cytoplasm |
Jelly-like substance in a cell that contains organelles |
|
Cell membrane |
Cell membrane is the outer layer of cells. The cell membrane is the boarder patrol, the membrane chooses what leaves and comes in |
|
10 characteristics to tell if something is alive |
-Made of cells. -Can reproduce asexually or sexually -Has a point of maturity. -Ability to lose living status. -Capable of movement. -Exhibited sensitivity to change in environment. -Able to adapt or evolve over time. -Capable of gaining energy. -Capable of transferring energy to suit organisms own needs. -Able to eliminate byproducts of energy transformations. - |
|
Sexual Reproduction |
-Sex cells fertilize and end up creating life. The offspring are not identical |
|
Asexual Reproduction |
Occurs without specialized cells. Offspring are identical in every way. There are 4 types of Asexual reproduction. |
|
Vegetative asexual reproduction |
Vegetative reproduction occurs when a plant is creates using segments of the same species of that plant. Example: Spider plants grow green flowers that you can plant to create an identical plant |
|
Fission asexual reproduction |
Fission reproduction occurs when a cell decides into two identical cells. This occurs frequently in our body while mitosis takes place. |
|
Spore formation asexual reproduction |
Spore formation asexual reproduction occurs when spores are spewed out of organisms like mold that latches onto other surfaces to create more, identical mold. |
|
Fragmentation |
Fragmentation occurs when an organisms limb is cut off and it grows the limb back while the limb grows an identical body. |
|
Muscle movement |
Has pairs, flexor and extensor. Generally depends on the integration of skeletal system. |
|
Locomotion VS motion |
Locomotion=Moving entirely Motion= part of you moves (hand and wrist move while writing) |
|
Cytoplasmic streaming |
Uses Circulation of cytoplasm to move around. Unicellular organisms like an Amoeba use this kind of movement. |
|
Growth movement |
Occurs primarily in plants. Very slow movement which occurs in response to stimuli. EX:"moving towards sun". -roots are a positive geotropism -stems are a positive phototropism |
|
Equation for photosynthesis |
CO2+H2O+light>O2+C6H12O6 Converts carbon dioxide and water to sugar and oxygen |
|
Mammal energy formula |
C6H12O6+O2>CO2+H2O+usable energy. Turns sugar and oxygen to carbon dioxide, water and usable energy. |
|
Synthesis |
Means building of a structure |
|
Nucleus |
Is control centre surrounded by a double membrane called the nuclear membrane, there is normally one per cell. DNA us found here |
|
Mitochondria |
Creates energy for the cell normally through cellular respiration. |
|
Chloroplast |
Contains chlorophyll that gives the plans its green pigment. Site of food production like glucose and sugar . made of cellulose |
|
Vacuoles |
Large central vacuoles are in plant cells, smaller ones are in us. Vacuoles store water and food |
|
Centriole |
Aids in cell division. Pulls the duplicated chromosomes apart creating daughter chromosomes (anaphase) |
