Complex Tissues in Plants

Plants have two types of tissues- simple tissues and complex tissues. Simple tissues are made up of only one type of cell, while complex tissues are made up of different types of cells.

Complex tissues are further classified into two types:

1. Xylem- responsible for conducting water and minerals from roots to leaves.

2. Phloem- responsible for conducting food materials from leaves to different parts of the plant.

Answer Explanation:

The correct answer is option B- Pteridophyta.

Pteridophyta are a group of seedless vascular plants that include ferns, horsetails, and club mosses. They are known for having vascular tissues, including xylem and phloem, which are responsible for conducting water, minerals, and food materials throughout the plant.

Therefore, it is incorrect to say that complex tissues are not present in Pteridophyta. Hence, option B is the correct answer.

On the other hand, some bryophytes, such as mosses, liverworts, and hornworts, do not have true vascular tissues and, thus, do not have complex tissues. However, some bryophytes, such as Sphagnum moss, have specialized cells called hyaline cells that function similarly to the xylem of vascular plants.

Furthermore, all gametophytes, including those of bryophytes and pteridophytes, do not have complex tissues. This is because gametophytes are haploid and do not require specialized tissues for conducting water, minerals, or food materials.

However, all spermatophytes, which include seed plants such as gymnosperms and angiosperms, have complex tissues. The xylem and phloem of spermatophytes are responsible for supporting the growth of the plant and the transport of water, minerals, and food materials.
