AUXIN is a hormone that is involved in TROPISMS. Which of the following is a result of it?

Tropism allows a plant to move in a certain direction

Tropism helps a plant go through photosynthesis

Tropism allows a plant to produce glucose

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 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 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.

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

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-attraction of pollinators, Y-production of male sex cells, Z-egg production and embryo development

X-pollen production, Y-pollen transfer, Z-production of eggs

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

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?

light sensors in the grass tips stimulated a hormone in the shoot system

Water evaporated faster on the side of the plant having full light

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

Since a growing seed cannot carry out photosynthesis, it is packaged with nutrients. Which two plant systems must interact to create nutrient-rich seeds?

Reproductive system and transport system

Root system and dermal tissue system

Excretory system and digestive system

Immune system and vascular tissue system

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
