Which of the following is correctly matched with its tissue system?
phloem ... epidermis pith ... vascular tissue system xylem ... ground tissue system cortex ... ground tissue system guard cells ... ground tissue |
cortex ... ground tissue system
|
|
|
Other than the transport of materials, what is another function that vascular tissue performs in a leaf?
The tissue functions as a skeleton that reinforces the shape of the leaf. The tissue contains a labyrinth of air spaces that allows for gas exchange. The tissue stores sugars produced by photosynthesis. The tissue regulates the opening and closing of pores in stomata complexes. The tissue contains the cells that perform photosynthesis. |

Select the best description of the significance of the meristems of plants.
Plant meristems are permanently embryonic regions within the plant body. Plant meristems are active only for repair of wounds or damage to plants. Plant meristems are present only in young plants. |

Select the correct statement about plant growth.
A plant may produce juvenile and adult leaves at the same time. Plant growth and form is determined solely by genetic factors. Nonwoody plants grow by primary growth, whereas woody plants grow by secondary growth. |

Plants and animals respond differently to the environment. Which statement most accurately compares the responses of plants and animals to changes in their environment?
Animals are better able to detect changes in their environment than plants because animals have sense organs, which plants lack. Animals are more responsive to changes in their environment than plants. Animals tend to respond to changes in their environment by movement; plants tend to respond to changes in their environment by growth |
Animals tend to respond to changes in their environment by movement; plants tend to respond to changes in their environment by growth
