Correct Answer: Option B
Explanation:
Explanation:
Different plant tissues have distinct functions, and some contain dead cells that play crucial roles, such as providing structural support or transporting water.
- Xylem vessels are made up of dead cells. These cells are lignified (contain lignin), which makes them strong and capable of conducting water and minerals from the roots to the rest of the plant. The cells die after they mature and their cell walls become thickened and rigid.
Let’s analyze the other options:
#A. Meristematic
- Meristematic tissue consists of living cells that are actively dividing and growing. These cells are responsible for the growth of plants, and they are not dead.
#C. Cambium
- The cambium is a type of meristematic tissue. It is made up of living cells that are actively involved in the growth and development of new tissues, such as phloem and xylem.
#D. Mesophyll
- Mesophyll tissue is found in the leaves and is made up of living cells. It contains two main types of cells: the palisade mesophyll (which is involved in photosynthesis) and the spongy mesophyll (which allows for gas exchange).
#E. Palisade
- Palisade tissue is a part of the mesophyll in leaves and consists of living cells that are primarily involved in photosynthesis.
Summary:
Xylem vessels are composed of dead cells that provide support and transport water in plants.
