B.10B Plant System Interactions 🏖️

Which plat response would best aid a plant in maximizing and retaining water acquired during a drought?

• Decreasing root growth, while increasing stem and leaf growth

• Increasing root, stem, and leaf growth

• Decreasing stem and leaf growth, while increasing root growth

• Increasing leaf and root growth, while decreasing stem growth

This question has two parts.

Roots of different plants can be connected by a network of underground fungal extensions called hyphae. These fungi contribute minerals to the plants, and the plants contribute carbohydrates to the fungi.

Positive thigmotropism is a response in plants in which they move and grow toward an object the plant comes in to physical contact with, usually curling around the object.

This response of the shoot system benefits the plant by allowing the plant to --

• produce more pollen from pollinators

• take in more carbon dioxide to convert into glucose

• absorb more water to transport to the leaves

• reach more sunlight for photosynthesis

Water, sugar, and other important nutrients need to be transported from one part of the plant to another. Which statement correctly describes the interaction of the root and shoot systems during nutrient transport?

• The leaves take in water and sugar, which are then transported to the rest of the plant through the vascular tissues.

• The roots take in water and sugar, which are then transported to the rest of the plant through the vascular tissues.

• The leaves take in water and the roots produce sugar that are transported to the rest of the plant through the vascular tissues.

• The roots take in water and the leavers produce sugar that are transported to the rest of the plant through the vascular tissues.

A flower that has both male and female reproductive structures is shown.

Which statement best describes an interaction that will allow a flowering plant to reproduce by self pollination?

• An anther is transferred from a filament to another filament within the same flower.

• An ovule is transferred from the ovary to a petal on a different flower.

• A pollen grain is transferred from an anther to the stigma of the same flower

• An ovary is transferred from a flower on one plant to a flower on a different plant.

What caused the shoots of the seedlings on the windowsill to bend toward the window?

• Hormones produced in response to a light stimulus

• sugars produced in response to a gravity stimulus

• Carbon dioxide produced in response to a water stimulus

• Water produced in response to a nitrogen stimulus

Gebberelins are hormones produced in the root tips of plants. The plant uses this hormones to stimulate the growth of shoots.

How are gibberelins able to affect other parts of the plant?

• Gibberelins are absorbed through the stomata and attach to chloroplasts

• Gibberelins are transported through vascular tissues to other parts of the plant.

• Gibberelins become concentrated within the tissues of the plant during mitosis

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

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
