Chapter 44, Problem 1MC

Taproots

a. are characteristic of dicots.
b. act as sugar sources when leaves are fully developed.
c. are filled with sclerenchyma cells.
d. include white potatoes.

Features Features Embryos with two cotyledons. Veins in leaves form a network, and flower sections are divided into multiples of four or five. The vascular tissue in dicots is arranged in a ring in the stem, whereas in monocots, the vascular tissue is dispersed across the stem. Eudicots develop either herbaceous (like grasses) or woody tissues. Pollen from most eudicots is trisulcate or triporate, meaning it has three furrows or pores. One main root formed from the embryonic radicle normally anchors the root system.

Expert Solution & Answer

Summary Introduction

Introduction:

The roots are the underground parts of the plant. The basic function is to absorb water and minerals and supply it to aerial parts of the plant. The roots also act as a storage unit for starch.

Answer to Problem 1MC

Correct answer:

The dicotyledonous plants exhibit the taproots. Therefore, option (a) is correct.

Option (a) is given as “are characteristic of dicots”.

Explanation of Solution

Justify reasons for the correct statement:

The major and first root emerged from the primary root system that grows in the downward direction is a taproot. This type of root is present in dicotyledonous plants. The secondary and tertiary roots emerge from the primary taproot that increases the absorption of water.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “act as sugar sources when leaves are fully developed”.

The roots become sugar sources when the leaves are developing and emerging and this continues until then the leaves are capable of performing photosynthesis. Hence, it is a wrong answer.

Option (c) is given as “are filled with sclerenchyma cells”.

The sclerenchyma cells are dead cells that provide support to plant parts. The roots do not have sclerenchyma cells because they need to absorb water from soil. Hence, it is a wrong answer.

Option (d) is given as “include white potatoes”.

The potatoes are modified stems, whereas, the modified roots are sweet potatoes and carrots. Hence, it is a wrong answer.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

The taproots are one of the characteristic features of the dicotyledonous plants.
