|---|---|---|---|---|---|
| Vascular plants are a group of plants with vascular tissue or transport tissue..this tissue also gives structure and support to these plants. What are the two types of vascular tissue | Xylem and Phloem ( Xylem tissue is a major support structure)
🗑
|
||||
| What is transported by Xylem... describe | Xylem transports water from the roots to the leaves
🗑
|
||||
| What is transported by Phloem... describe | Phloem transports food ( sugars and other organic compounds) throughout the plant ..not just from roots ( from leaves and stems to roots and from roots to leaves and stems. REMEMBER FLOWUM.... FOOD...sounds very similar
🗑
|
||||
| What and where is the leaf's cuticle and what is it's function | it is a noncellular waxy layer on top of the epidermis layer. It helps prevent water loss ( slows evaporation) and helps prevent bacteria and other disease-causing organisms from entering a plant
🗑
|
||||
| Describe the epidermis of a leaf | there are two epidermal layers (an upper epidermis and a lower epidermis).. they typically don't have chloroplasts and don't do photosynthesis.. their function is mainly protection ( this layer also has the cuticle mentioned on another question
🗑
|
||||
| What is usually found on the lower epidermis (it can be on the upper epidermis but not typically) | stomata, stoma, or stomates ( all the same thing)
🗑
|
||||
| What are stomates ? | they are pores that serve as passageways for oxygen gas, carbon dioxide gas, and water vapor
🗑
|
||||
| What are guard cells? | they are paired cells on either side of the stomata , they contain chloroplasts and do photosynthesis in order to open or close the stomata
🗑
|
||||
| What leaf layer does the most photosynthesis... What leaf layer is also important for photosynthesis | the palisade does the major photosynthesis. The spongy layer is also important for this purpose.. ... they both have chloroplasts seen as small dots in the cross section of a leaf
🗑
|
||||
| What is another function of the spongy layer other than photosynthesis | It has loosely packed cells that allow the carbon dioxide , water vapor, and oxygen circulate freely
🗑
|
||||
| What term describes loss of water through the stomata ( water evaporating through the stomata) | transpiration
🗑
|
||||
| What gas or gases leave the stomata | oxygen and water vapor
🗑
|
||||
| What gas or gases enter the stomata | carbon dioxide
🗑

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.
