Question

The infective stage of Entamoeba histolytica is:

• A. Minuta
• B. Trophozite
• C. Mature Cyst
• D. Sporozite

Answer 1

The Correct Option is C

Answer (c) Mature Cyst

Answer 2

The transmissive or infective stage of Entamoeba histolytica is represented by tetranucleate cysts, which do not grow further but instead leave the host in faeces. They withstand desiccation very well and last for around 12 days. Their illness is caused by consuming tainted food or drink.

Answer 3

Let's examine the possibilities to choose the right response.
Option A: Invagination takes place while an embryo is in the gastrulation stage of development. When an extended finger is placed radially against a partially inflated balloon, an embryo will produce a tube on its surface. Axial and orthogonal invagination are the two basic types. As a result, this is the wrong choice.
Option B: An organism's origins as a diploblastic or triploblastic creature are unrelated to the number of heads present during embryonic development. As a result, this is the wrong choice.
Option C: During embryonic development, during which the cells split into the endoderm, ectoderm, and mesoderm layers, germ layers are generated. Mesoderms are the intermediary layer that lies between the endoderm and ectoderm, making up the innermost germ layer. Ectoderm makes up the outermost germ layer. The classification of organisms as diploblastic or triploblastic is based on the existence of layers. While triploblastic species have endoderm, endoderm, and mesoderm as their three layers, diploblastic organisms only have endoderm and ectoderm. This is the best choice as a result.
Option D: Different cell types are present at different times throughout development, giving birth to layers as the body develops. It has nothing to do with the genesis of any organism, triploblastically or diploblastically.  As a result, this is the wrong choice.
