Plant roots have extensions called root hairs. These root hairs are important in the homeostasis of the plant. Which statement best explains the importance of the root hairs to the stems and leaves of the plant?
root hairs convert minerals into glucose for immediate use by cells
root hairs decrease the need for osmosis and diffusion in vascular tissue
root hairs prevent water loss in leaves through transpiration and gas exchange
root hairs increase the surface area of the roots for nutrient and water absorption

Some type of energy
Water
Oxygen

The diagram show the reproductive system of a plant. Which of the following best describes the interaction that occurs between a plants reproductive arts during fertilization?
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the stule and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the filament, where the sperm fertilizes the egg.
The internal transport of water and minerals in plants requires that two systems work together. Which correctly describes how the two systems accomplish this task?
absorption through the root system, then transport through the shoot system by vascular tissue and stomata in leaf tissue
exchange of minerals for water in the root system, then transport of minerals through phloem to leaves in the stem system
transpiration by the guard-cell and leaf systems, then sweating into the soil by the root system
absorption of water by the leaf system, then transport through the meristematic system
Structures represented in the illustration below are found in the lower epidermis of a plant leaf. The illustration at right shows the response to a certain environmental condition. The response represented in the illustration would most likely be caused by --
a reduced supply of oxygen
long periods of rainfall
high concentrations of glucose
little available water
Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower. Which table correctly identifies the function of each structure or group of structures in the reproduction of a plant?
X-pollen production, Y-pollen transfer, Z-production of eggs
X-attraction of pollinators, Y-production of male sex cells, Z-egg production and embryo development
X-protection for embryo, Y-supply nourishment to embryo, Z-place of embryonic development
X-photosynthesis, Y-production of cells that protect internal organs, Z-production of egg and sperm
Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?
vascular system
dermal system
reproductive system
none of these
A student conducted an investigation to study the phototropism in grasses. The only difference between the control group and the experimental group was light conditions. The control group was provided full light, while the experimental group was shaded on one side. The diagrams show the average heights and positions of blades of grass in the investigation. Which statement best explains why the grass tips of the experimental group bent toward the light?
Water evaporated faster on the side of the plant having full light
light sensors in the grass tips stimulated a hormone in the shoot system
the xylem in the root system absorbed more nutrients from the shaded side
the side facing the light has a greater chance of absorbing carbon dioxide from the atmosphere
Why are root hairs important to the roots, stems, and leaves of plants?
they increase the surface area of the roots allowing them to absorb more water
they transport water to other areas of the plant for photosynthesis
they produce hormones needed throughout the rest of the plant
they create seeds or spores so the plant can reproduce
Plants have hormones just like humans do. Plant hormones are created in the plant's stem, buds, and root tips. These hormones are carried and distributed throughout the plant by the plant's ____________________ system. Which of the following correctly completes the sentence?

dermal
root
