The index fossils have a shorter time period and wider geographical distribution of fossils.
An Index fossils refers to class of fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time.
They helped in the construction of geological periods that are commonly used today.
Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.
Therefore. the Option B is correct.

Answer:
Option (2)
Explanation:
Index fossils are defined as those fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time. They had great significance in the field of paleontology. It helped in the construction of geological periods that are commonly used today. It basically helped in forming the geological time scale. The age of the rocks in which these fossils were embedded is easily determined by using radioactive dating techniques.
Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.
Hence, the correct answer is option (2).

Vascular tissue consists of xylem and phloem.
Explanation:
Vascular tissue could be a advanced conducting tissue, shaped of over one cell kind, found in vascular plants. the first parts of plant tissue are the vascular tissue and vascular tissue. These 2 tissues transport fluid and nutrients internally. The cells in plant tissue are generally long and slender
Phloem make up the vascular tissue. It helps in the transportation of the food prepared by the leaves of the plant.
Further Explanation:
Phloem is made up of vascular or livingtissue. It uses the turgor pressure that helps in the transportation of sugar to each part of the plants. It also supports the transportation of proteins and m RNA (messenger ribonucleic acid) to each region of the plants.
Phloem is composed of certain specialized cellssuch as sieve tubes, phloem fibers, companion cells and parenchyma cells. The phloem is divided into two types namely; primary phloem and secondary phloem. The primary phloem consists of the apical meristem. It is a region of new cell formation. It lies on the tip of root and shoot. It is further divided into two types; protophloem or metaphloem. The cell of Protophloem mature before elongation, whereas metaphloem mature after cell elongation. Secondary phloem resides in the plant that have a cambium.
