Answer:
The two cell types in xylem tissue are tracheids and vessel elements. Xylem is a vascular tissue that helps in the transportation of plants. Tracheids are found in most gymnosperms, ferns, and lycophytes whereas vessel elements form the xylem of almost all angiosperms.
Xylem can be found in vascular bundles, present in non-woody plants and non-woody parts of woody plants.
Step-by-step explanation:
The two cell types in xylem tissue are tracheids and vessel elements. Tracheids are found in most gymnosperms, ferns, and lycophytes, while vessel elements form the xylem of almost all angiosperms.
Tracheids are long, narrow cells with pointed ends. They have thick walls and are arranged in rows. Tracheids transport water and minerals from the roots to the leaves.
Vessel elements are shorter and wider than tracheids. They have thinner walls and are connected end to end to form long tubes. Vessel elements also transport water and minerals from the roots to the leaves.
Xylem tissue is found in the vascular bundles of plants. Vascular bundles are groups of cells that transport water, minerals, and food throughout the plant. Xylem tissue is also found in the secondary xylem of woody plants. The secondary xylem is the woody part of the stem or root that forms after the primary xylem.
