|---|---|---|---|---|---|
| Cuticle | reduces water loss
🗑
|
||||
| Upper Epidermis | supports; clear to let light through
🗑
|
||||
| Palisades Layer | main photosynthetic tissue
🗑
|
||||
| Spongy Layer | contains air spaces for diffusion of c02 in, 02 out
🗑
|
||||
| Stomate | opening that lets co2 in and 02 out
🗑
|
||||
| Guard Cell | closes stomate to reduce water loss
🗑
|
||||
| Xylem | transports water from roots to leaves
🗑
|
||||
| Phloem | transports food leaves to roots
🗑
|
||||
| Vein | combined xylem and phloem
🗑
|
||||
| Lower Epidermis | contains stomates
🗑
|
||||
| What is the general equation of photosynthesis? | co2 + h20 -------> c6h1206 + 02
🗑
|
||||
| what are the 2 sets of reactions that take place in photosynthesis | light dependent and light independent
🗑
|
||||
| light dependent reaction | (aka photochemical)uses sunlight to break water free electrons to make ATP and NADPH
🗑
|
||||
| light independent reaction | (ask carbon fixation) uses NADPH, ATP from light reactions to make glucose
🗑
|
||||
| What is photolysis? | breaking down of water with suns energy
🗑
|
||||
| When in the chloroplast does photolysis occur? | thylakoid
🗑
|
||||
| What are the reactants and products of photolysis? | reactants: water, sun products: H+, o2, e-
🗑
|
||||
| What is carbon fixation? (calvin cycle) | co2 ---> C6H12O6
🗑
|
||||
| Where does carbon fixation occur? | stroma
🗑
|
||||
| What are the reactants and products of carbon fixation? | reactants: CO2 products: glucose
🗑
|
||||
| What is chlorophyll? | pigment that absorbs light and transfers energy
🗑
|
||||
| What wavelengths (colors) of light does photosynthesis occur at the quickest rate? | blue, red, violet
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
