Question

(a)Differentiate between:

(i) Nucleus and nucleoid

(ii) Plant cell and animal cell

(b)What is osmosis​

Answer 1

Answer:

1. The nucleus is a membrane-bound organelle within the cytoplasm where the genome is housed in a eukaryote.

• The nucleoid region is just the spot in the cytoplasm of a prokaryotic cell where the genome happens to be hanging out -- the genome is not separated from the rest of the cytoplasm by any membrane.

2. The nucleus is present in both the cells, but in Plant cell it lies on one side while it is present in the center of the Animal cell. Centrosomes/Centrioles, Cilia, Desmosomes, Lysosomes are the organelles found absent in Plant cells, while they exist in Animal Cells.

3.a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.

Answer 2

Answer:

osmosis:-the movement of solvent from the region of its high concerntration to low concerntration through a semi permiable membrane is called osmosis
