How does primary growth happen? |
1)Cell division by mitosis 2)Cell enlargement as water fills the vacuole 3)cells become specialised |
|
|
Why does a plant need to undergo primary growth? |
Block out competitors Reach sunlight |
|
|
How does secondary growth happen? |
1)Cambium in vascular bundles grows by mitosis. 2)undifferentiated cells on the outside of the cambium become secondary phloem. The initial phloem gets crushed - these become cork cambium. 3)undifferentiated cells on the inside of the cambium become secondary xylem - these become growth rings |
|
|
What is tropism? |
A plant's growth response to an environmental stimulus |
|
|
How does positive photo tropism work? |
Auxin produced in the apical meristem, moves to the shaded side causing cells to elongate. As auxin will denature in direct sunlight only the cells on the shaded side will elongate meaning the plant is pushed toward the sun |
|
|
Name the 7 bits of the leaf |
Waxy cuticle, upper epidermis, palisade layer, spongey mesophyll layer, vascular tissue, stomata, guard cells |
|
|
What goes on the X and y axis |
X independent which is the change. Y dependent which is the results. |

|
|
What is a capillary? |
In between arteries and veins. They are one cell thick for quick diffusion. Because they are so thin, 02, hormones and nutrients can flow in, and waste like Co2 and urea can flow in. THEY CONTAIN BOTH OXYGENATED AND DE-OXYGENATED BLOOD |
