Question

Which of the the following statements about plant divisions is false?

a. Lycophytes and pterophytes are seedless vascular plants.

b. All vascular plants produce seeds.

c. All non-vascular embryophytes are bryophytes.

d. Seed plants include angiosperms and gymnosperms.

Short answer

The correct answers is (b). All vascular plants produce seeds

Step-by-step solution

Introduction

• The green algae and land plants are grouped under the subphylum Streptophyta and are called Streptophytes.
• The land plants are further divided into Vascular and Non-vascular based on the presence of vascular tissue.
• Non-vascular plants include the seedless plants, bryophytes.
• Vascular plants are divided into seedless plants and seed plants. Seedless plants include lycophytes and pterophytes and seed plants include the gymnosperms and angiosperms.

Explanation for the correct answer

• Vascular Plants are divided into seedless plants that do not produce seeds and seed plants that produce seeds.
• Seedless plants are further divided into two types the lycophytes and pterophytes.
• Seed plants are also divided into types, Gymnosperms that produce naked seeds and Angiosperms, also called flowering plants, that produce seed within fruits.

Hence, option (b) is the correct answer

Explanation for the incorrect options

a. Lycophytes and pterophytes are seedless vascular plants.

Lycophytes and pterophytes are plants with vascular tissue that do not produce seeds. Hence this statement is true and the option is incorrect.

c. All non-vascular embryophytes are bryophytes.

Non-vascular embryophytes are the bryophytes that do not possess vascular tissue and do not produce seeds. Hence this statement is true and the option is incorrect.

d. Seed plants include angiosperms and gymnosperms.

Seed plants are of two types, angiosperms also known as flowering plants that produce seed within a protective covering called fruit and gymnosperms that produce naked seeds without any covering. Hence this statement is true and the option is incorrect.
