Question 8.
What is the function of sieve tube cells and how they are designed to carry out their function? Question 9.
What are semiautonomous organelles? Describe with example?
Answer
Mitochondria and chloroplasts are called semi-autonomous organelles because they have their own DNA, mRNA, TRNA, ribosomes and they replicate by binary fission so they are said to be self governing. Semi-autonomous means they are in a symbiotic relationship with the cell and have evolved to become part of it.
Question 10
Why plasma membrane is called selectively permeable?
Answer
Plasma membrane allows some material to pass through it while on the same time it blocks other material from entering through it
This is mainly because of the sizes and polarity of molecules.
