Life organized from smallest organism to biggest organism. |
Atom<Molecule<Cell<Organism |
|
|
How is a cell different than an atom? |
A cell is the base unit of life, and matter makes up all matter, even matter that isn't living. |
|
|
Characteristics of living things |
Made of cells Use energy Grow Develop Sense and respond to change Has DNA Reproduce |
|
|
Why is a cell considered the "smallest unit of life"? |
A cell has all 7 of the characteristics of life. Therefore, it is the smallest thing that is considered alive. |
|
|
Prokaryotic Cells vs. Eukaryotic Cells |
Prokaryotic: No nucleus, no membrane covered organisms, circular DNA, bacteria. Eukaryotic: Has nucleus, membrane covered organisms, linear DNA, all other cells. |
|
|
Why is a plant cell eukaryotic? |
A plant cell is eukaryotic because it has a nucleus. |
|
|
Why do plant leaves need cholorplasts? |
Chloroplasts are the organelle that conducts photosynthesis. Photosynthesis is needed in plants for energy. |
|
|
Why do chlorplasts need the pigment of chlorophyll? |
Chlorophyll is the pigment that absorbs the sunlight in the chloroplasts. The sunlight is then used for photosynthesis. |
|
|
Photosynthesis Equation |
C02 + H20 ---Sunlight------> C6H12O6 + O2 Reactants Products |
|
|
Where does the carbon molecule end up? |
The CO2 is broken up into Carbon and Oxygen. The oxygen then gets released into the air, but the carbon gets put in the glucose. |
|
|
Where does the energy from the sun go in the photosynthesis reaction? |
The energy from the sun goes into the proccess of photosynthesis to help create the molecules oxygen and glucose. |
|
|
Reactants and Products of photosynthesis. |
Reactants: CO2(air), H2O(water) Products: C6H12O6(glucose), O2(Oxygen) |
|
|
Why do we humans need photosynthesis in our world? |
Plants rely on sunlight to go through photosynthesis to make their own food. We can't use the sun's energy directly, so we have to eat the plants to recieve that energy. |
|
|
Why is the control plant living? |
The 7 characteristics of life: Has cells Grows Reproduce Develops Has DNA Use energy Sense and respond to change |
