Differentiate between
a) Nuclear region of bacterian cell and nuclear region of animal cell
b) Cork and epidermis
c) Osmosis and diffusion
d) Chromatin and chromosome
e) Cells of meristematic tissue and cells of permanent tissue
f) Bone and cartilage
Answers
Answer:
a.ans :
In nuclear region of bacterial cell Their is absence of nuclear membrane hence they are called prokaryotes. In nuclear region of animal cell nuclear membrane is present hence they are eukaryotes.
b.ans :
An epidermis is a single-layered group of cells which are used for covering the plant leaves, roots, stem, and flowers. ... The cork, on the other hand, is a waterproof protective layer which can be found on the cork trees and consists of dead cells and this is impermeable in nature.
c.ans : Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
d.ans :
The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between .
e.ans :
Difference between Meristematic and Permanent Tissue
Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth. Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions.
f.ans :
Cartilage and Bone are specialised forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. ... Cartilage is thin, avascular, flexible and resistant to compressive forces. Bone is highly vascularised, and its calcified matrix makes it very strong.
