🗑
|
||||
| Nonvascular | The lack of tissue to transport materials within a system
🗑
|
||||
| Vascular | Consisting of tissue that can transport materials with the use of vessels or xylem and phloem
🗑
|
||||

🗑
|
||||
| Guard cells | Curved cells that surround a stomate, becoming larger or smaller according to the pressure within the cells
🗑
|
||||
| Roots | Part of a plant that attaches it to the ground or to a support, carrying water and nourishment to the rest of the plant
🗑

🗑
|
||||
| Stems | Main body or stalk of a plant or shrub, typically rising above ground
🗑
|
||||
| Root system | System found below ground and includes many organs to perform the function of absorbing nutrients and water
🗑
|
||||
| Vascular system | System consists of xylem and phloem responsible for transport
🗑
|
||||
| Flowers | Holds the male and female reproductive organs of angiosperms
🗑
|
||||
| Fruit | Provides the covering for seeds and can be fleshy like an apple or hard like a nut
🗑
|
||||
| Stamen | Male reproductive structure composed of the anther and the filament
🗑
|
||||
| Pistil | Female reproductive structure composed of stigma, style, and ovary; also known as carpel
🗑
|
||||
| Pollen | Male sex cell, plant sperm
🗑
|
||||
| Pollination | Act of transferring pollen grains from the male anther of a flower to the female stigma
🗑
|
||||
| Petal | Leafy structures that comprise a flower; usually used to attract a pollinator
🗑
|
||||
| Seeds | Embryonic plant enclosed in a protective outer covering
🗑
|
||||
| Style | Connects the ovary and the stigma and is where the pollen tubes grows
🗑
|
||||
| Ovule | Female reproductive cell that will become the seed once fertilized
🗑
|
||||
| Pollinator | Anything that moves polle into the ovary of the same plant or another plant of the same kind
🗑
|
||||
| Stigma | Place where pollen germinates after the pollen lands
🗑
|
||||
| Phototropism | Growth of plants toward a light source
🗑
|
||||
| Geotropism | Growth of plants in response to gravity
🗑
|
||||
| Tropism | The response of an organism, especially a plant, to an external stimulus by growth in certain direction
🗑
|
||||
| Thigmotropism | Growth of plants in response to touch
🗑
|
||||
| Hydrotropism | Response of plants to water
🗑
|
||||
| Auxin | Plant hormone that is made in the tips of plant cells; they determine how long a cell will grow
🗑

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.
