Answer: Option B. -> Lysosome − Protein synthesis
:
B
Protein synthesis takes place in ribosome, which are attached to surface of endoplasmic reticulum byribophorin –I andribophorin – II. About 50 hydrolytic enzymes are found in the lysosome. They include proteases, nucleases,glycosidases, lipases phospholipases, phosphatases andsulphatases. Alllysosomal enzymes are acid hydrolases and optimally active at pH-5.0.

Answer: Option A. -> Dictyosome
:
A
Dictyosome or Golgi complex is present in higher number in secretory cells. All glandular cells depend on Golgi complex for concentrating and pouring their secretion to the outside.

Answer: Option B. -> Spindle formation and cell division
:
B
Thecytoskeletonof a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organise the cell's parts. In addition, microtubules provide a basis for movement and cell division.

Answer: Option A. -> Exocytosis
:
A
The movement of macromolecules such as proteins or polysaccharides into or out of the cell is calledbulk transport. There are two types of bulk transport,exocytosisandendocytosis, and both require the expenditure of energy (ATP). Inexocytosis, materials areexportedout of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane.

Answer: Option A. -> mitochondria and inherited via egg cytoplasm
:
A
The cytoplasm of eukaryotic cells contain organelles such as mitochondria, chloroplasts, Golgi bodies, lysosomes peroxisomes, etc. Out of these mitochondria and chloroplasts contain DNA which inherited via egg.
