Question

_____are the forms of complex tissue.
A. Xylem and phloem
B. Epithelium and meristem
C. Xylem and epithelium
D. None of these

Answer 1

Hint: Simple tissues consist of single types of cells while complex tissues have many types of cells. Complex tissues perform very important functions of the plant. Xylem and phloem tissues help to transfer water and minerals throughout the plant.

Complete answer:
Complex tissue is a tissue consisting of many cells working together. The epithelium is a type of animal tissue hence, it cannot be considered as complex tissue. Xylem is a permanent tissue that has tracheids, vessels, xylem parenchyma. It carries out the function of conducting water across the plant body. Phloem is a permanent complex tissue. It consists of sieve tubes, companion cells, phloem fibers and phloem parenchyma. It is present in the same location as xylem. It transports food from leaves to other parts of the plant body.
Parenchyma is simple tissue which helps in photosynthesis, wound healing, food and waste storage. In xylem and phloem, stem cortex and pith; root cortex, leaf mesophyll.
Epidermis is a complex ordinary epidermal cell, guard cells, cells of trichomes. It is a barrier between plant and environment. Outermost cell of stems, leaves, and roots.
Meristem is a type of tissue in plants that consists of meristematic cells that are capable of cell division. Protoderm will become the epidermis, and ground meristem tissues consist of parenchyma, collenchyma and sclerenchyma cells. Procambium will become the vascular tissues (xylem and phloem).
From the above information we know that xylem and phloem are the forms of complex tissue.

So, the correct answer is option A.

Note: Many absorption tissues are present in plants that are simple and primary tissues. Rhizodermis or root hairs originate from protoderm. Secretory tissues spread across the plant body. They help in the secretion of latex, volatile oils, mucus, and other chemicals from the plant. They also help in attraction or dis-attraction, communication or defense, and many others.
