Which table correctly identifies the function of each structure in the reproduction of the plant?

• X=produce pollen, Y=transfer pollen, Z=produce eggs

• X=embryo protection, Y=nourishment for embryo, Z=place of embryo development

• X=attracts pollinators, Y=produce male sex cells, Z=egg production and embryo development

• X=photosynthesis, Y=produce cells that protect organs, Z=produce egg and sperm

Structures shown in the image are found in the lower epidermis of a plant leaf. The image shows a response to a certain environmental condition. The response represented would most likely be caused by --

• a reduced supply of oxygen

• long periods of rainfall

• high concentrations of glucose

• little available water

Plant roots have extensions called root hairs. These root hairs are important in the plant's homeostasis. Which answer 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.

"Gibberellins" are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots. How are gibberellins able to affect other parts of the plant?

• They are absorbed through the stomata and attach to chloroplasts.

• They are transported through vascular tissues to other parts of the plants.

• They become concentrated within the tissues of the plant during mitosis.

• They become modified once they infect healthy cells and are later released to infect other cells.

Copper is a micronutrient found in soil. It is important for reproductive growth in plants and plays a role in chlorophyll production.

Which statement describes the interaction that occurs between the root and shoot systems of plants to allow reproduction to occur?

• Copper is produced in roots when copper-containing compounds are hydrolyzed.

• Copper is absorbed by the roots and transported to reproductive tissues by the shoot system.

• The shoot system stores copper for later use by the roots and the reproductive structures.

• The shoot system transports copper to the roots after it is taken in through the stomata in leaves.

Leaves are part of a plant's shoot system. The xylem tissue in leaves transports --

• the bacteria needed for nitrogen fixation in root nodules

• the wax required to coat the surface of actively growing tissue

• the water and minerals that are absorbed by the roots

• the oxygen that regulates the rate of carbohydrate production

How do plant systems work together to make the movement of liquid possible?

• Roots absorb water and minerals and move them up the stem, while the stem moves food from the leaves down to the roots.

• Roots anchor the plant in soil, and the stem holds the leaves up.

• Roots absorb their own water and minerals, while the stem absorbs its water and minerals through the leaves.

• Roots lose water vapor to the soil, and the stem loses water vapor through the leaves.
