Question
Chapter 35, Problem 1S
Summary Introduction
To determine:
The unfamiliar vegetable is a root or a stem based on its external features and a microscopic examination of its cross section.
Introduction:
The roots helps the plant to anchorage it into the soil. It helps in the absorption of water and minerals from the soil. Stems support leaves to maximize the light absorption part and helps in conduction of the water and minerals across the plant.

Students have asked these similar questions
If you were given an unfamiliar vegetable, how could you tell if it was a root or a stem, based on its external features and a microscopic examination of its cross section?
Someone gives you a plant structure that was found growing in the soil and asks you to determine whether it is root or an underground stem. How would you identify the plant part without a microscope? With a microscope?
As part of an experiment you are required to observe the external features of a fern.
State what microscope would you use and give reasons why?
You have been provided with a plant showing the rooting system and the stem with several leaves.
Give SIX features that you will look for to determine whether this is a monocotyledonous plant or a
dicotyledonous plant. Present your answer in a clear, logical manner.
In an experiment students were given the following materials and apparatus:
- juices from three local fruits; 4% glucose solution; Benedict's solution; test tubes,
beakers, syringes and boiling water bath.
Describe CLEARLY the procedure that can be used to estimate the amount of glucos
present in each juice. Use numbered steps in your answer.

One version of this device, called a leaf chamber, is shown below. When a scientist uses this device on a plant, they don’t need to break the leaves off the branch or stem they are attached to. The leaf chamber makes an airtight seal around the stem or branch even though it is sticking out of the chamber. Using this device, scientists detected the most change in O2 and CO2 levels inside the chamber when a leaf is in the chamber. They only detected a small change in O2 and CO2 levels in the chamber when a green stem was placed in the chamber. No change was detected when a root or a brown stem was placed in the chamber. Why do you think a scientist would prefer not to remove the leaves from a tree or a plant in order to take these sorts of measurements?arrow_forward
