Question

Butterflies, moth and honey bees and beetle lay which type of eggs?

• A. Microlecithal
• B. Mesolecithal
• C. Telolecithal
• D. Centrolecithal

Answer 1

The correct option is D Centrolecithal

Centrolecithal eggs describes the placement of the yolk in the centre of the cytoplasm of ovums. Many arthropods like butterflies, honey bees and beetle have this type of eggs. During cytokinesis, centrolecithal zygotes undergo meroblastic cleavage, where the cleavage plane extends only to the accumulated yolk and is superficial. This is due to the large dense yolk found within centrolecithal eggs and triggers a delayed embryonic development.
