buds, etc.
Question – 5 - Which tissue makes up the husk of coconut?
Answer: Sclerenchyma
Question – 6 - What are the constituents of phloem?
Answer: Phloem is composed of sieve tubes, companion cells,

Answer: Skin: Epithelium, Bark of tree: Epidermis, Bone:
Connective tissue, Lining of kidney tubule: Cuboidal Epithelium, Vascular
bundle: Complex plant tissue
Question – 12 - Name the regions in which parenchyma tissue is
present.
Answer: Parenchyma is present in mesophyll of leaves, fruits,
flowers and young stem.
Question – 13 - What is the role of epidermis in plants?
Answer: Epidermis in plants provides protective covering to the
