Imagine a calcium ion that has just entered a root tip. Before it can enter the vascular cylinder to be transported up to a growing leaf above ground, the ion must pass (i.e. either go through directly or go behind/around) __________.

You drive a nail into the trunk of a young tree that is 3 meters tall. The nail is about 1.5 meters from the ground. Fifteen years later, you return and discover that the tree has grown to a height of 30 meters. About how many meters above the ground is the nail?

Examine the eudicot root tip below, with 4 parts/tissue layers labeled. Use this figure to answer the following 2 questions.

A fibrous root system ___________________.

Which of the following statements about the Casparian strip is/are true?

1B – Name one structural or functional similarity, and one structural or functional difference between the cell types in the pairing you chose above. (1 sentence limit for similarity, 1 sentence limit for difference)

1B – Select which pairing you’ll be discussing:

Question 3C Explain – why is a carrot not very capable of the function you named first in question 3B, compared to other roots? (limit 1-2 sentences)

Use the labeled cross section of a leaf shown below to answer the following two questions.

Question 2D Let’s revisit our eudicot root L.S. from the multiple choice. On your handout, draw what the mature region of this root would look like in cross-section. You do not need to draw every individual cell, you may use shading to show different tissue layers. However, your drawing should be discernible, with any identifiable cell features or organization found in each tissue layer shown. Label the regions where dermal tissue, ground tissue, and vascular tissue would be found. That is all you need to label – dermal tissue, ground tissue, and vascular tissue. You don’t need to write anything below. If you’d like you can tell me a joke!
