E) Limbs
F) Spinal cord
Answer this question please
Answers
Explanation:
A.Bark of tree => Cork ( Secondary meristem ). >> Bone => Connective tissue. ... Vascular bundle => Complex permanent tissue ( Xylem and phloem ).
B.Shell of wallnutsb=>Sclerenchyma is the tissue present in hard covering of seed of Walnut mean Walnut shell. Lignin is responsible for making tissue hard. Leaf veins contains two types of tissues i.e., xylem and phloem.
C. Kidney tubules => Columnar epithelium - Cells of this tissue are pillar and column-like. These are present in the lining of the stomach and intestine. Cuboidal epithelium - Cells of this tissue are cuboidal in shape. They are found in kidney tubules, salivary glands, sweat glands, etc.
D. Lining of blood vessels =>The endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels. It is a thin layer of simple squamous cells called endothelial cells.
E. Limbs =>Epithelial tissues are tightly packed and form a continuous sheet. Tissues in Limbs - Muscular Tissues (voluntary muscles). - This tissue helps in the movement of the limbs. - It contains proteins and are long, cylindrical, unbranched and multinucleate.
F. Spinal cord=> The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.
