Which of the following is an example of an animal cell that lacks a nucleus in its mature form? MCQ with Answer and Explanation

Explanation:
Simple permanent tissues (parenchyma, collenchyma, sclerenchyma) consist of a single cell type. Meristematic tissues are dividing and have thin walls; xylem/phloem are complex; epidermis is dermal.

Explanation:
Cutin, along with waxes, forms the cuticle on the epidermis of leaves and stems, reducing water loss and providing protection. Lignin strengthens cell walls, cellulose is the wall polysaccharide, suberin is in cork cells and root endodermis.

Explanation:
Apis cerana indica (the Indian honeybee) is the most commonly domesticated species for commercial apiculture (beekeeping) in India. It is well-adapted to the local climate and is less aggressive than Apis dorsata (the rock bee). Apis mellifera (the Italian bee) is also widely used globally and in India for its high honey yield and gentle nature. Apis florea is the little bee, which is not suitable for commercial beekeeping.
