Day 8: Plant Systems

Select the answer that best matches the statements.

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

The stem and leaves are part of a plant's shoot system. The xylem tissue in the stem and leaves transports...

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

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

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?

A chart of some plant systems and functions is shown.

Which system interactions are dependent on the plant’s ability to respond to the direction of light?

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?

A corn plant produces both male and female flowers. The male flower forms the tassel and the female flower forms the ear of corn. The silks that emerge from the ear are the stigma of the female flower. Each silk leads to an ovule that can become a corn seed.

Which of these must happen for corn seeds to develop on the ear?

Students set up a controlled experiment by growing the same type of seedlings in two different locations. After a period of time, the students observed the seedlings and recorded their observations in the table shown.

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

Which location correctly identifies equivalent structure in animal cell?

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 the plant?

A chart of some plant systems and functions is shown.

Which system interactions are dependent on the plant's ability to respond to the direction of light?

Structures represented in the illustration below are found in the lower epidermis (on the bottom) of a plant leaf.

The illustration on the left is under normal conditions, while the illustration on the right shows the response to a certain environmental condition.

The response represented in the illustration above would most likely be caused by...

Plants called sundews have rounded green leaves with many hair-like structures. The ends of these structures contain enzymes in a sticky liquid that looks like nectar or moisture, as shown in the picture. The hairs do not react to dust or nonliving material but will bend inward when insects get caught in the sticky liquid. Sundews digest trapped insects over a period of a few days.

Based on this information, what function do the specialized leaves of sundews perform?
