Write 4 things you know about plants

2. Plant system lab

3. Station 1 A- Chloroplast

4. Station 1B Exposure to sunlight is reduced in the winter
During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves

5. Station 2- Tropism Geotropism Phototropism
Thigmotropism -vine climbing
thigmotropism

6. Station 3- Stomata
In plants, a specialized cell on the undersurface of leaves for controlling gas exchange and water loss. Guard cells occur in pairs
During warm weather, when a plant is in danger of losing excessive water, the guard cells close, cutting down evaporation from the interior of the leaf

7. Station 4- Veins Pipelines: Xylem and Phloem Xylem transports water
Phloem transports nutrients/ food

8. Station 5: Celery osmosis
Red dots represents xylem

9. Arrangement of vascular bundles in the roots and stems
Monocot roots:
Vascular bundles are in a ring.
Monocot stems:
Vascular bundles are scattered.

10. Monocot leaves have parallel venation.
corn
grass
orchid

11. Dicot stems –
Vascular bundles arranged in a ring
Dicot roots –
xylem in the center of the root and phloem outside the xylem.

12. Leaf Venation
(arrangement of veins in the leaf)

13. Monocot
Dicot

14. Analysis Discovered fossil has parallel vein arrangement in leaves:
Vascular bundle in root arranged in ______
RING (inner)
B. Vascular bundle arranged in stem: _________
SCATTERED (like chocolate chipped cookies)
Is plant a monocot or dicot : ____________
MONOCOT
