Question

in animal cell amembranous cell organelles are-??​

Answer 1

Ribosomes and Centrosomes are the amembranous organelles of cell in animals.

Ribosomes:

1. Ribosomes are the most important cell organelle which is composed of proteins and also composed of RNA. It is not covered by any membrane.

2. It plays a vital role in synthesising important proteins by converting the genetic codes into amino acid chains.

3. In animals, 80S ribosomes are found and is found located inside the cytosol.

Centrosome:

1. Centrosome is a cell organelle which does not have any membrane surrounding it.

2. It has an important role in the process of division of cells.

3. While cell division, the two centrosomes which was duplicated before the starting of division starts moving to the opposite cell poles.

Answer 2

Answer:

In animal cell membraneless cell organelles are ribosomes,  centriole and centrosome.

Explanation:

Amembranous are those organelles, who do not have any membrane around them.

• The ribosomes are not membrane bound structure,it is made up of RNAs and proteins. Most eukaryotes contains two distinct types of ribosomes,one is cytosolic and another one is organellar. Cytosolic ribosomes are 80s types and organeller ribosome are of 70s types.
• A centriole is barrel shaped polarized structure made up of microtubules. A pair of centrioles present in the microtubular organizing center ( MTOC).The MTOC with a pair of centrioles is known as centrosome.
