. there fins help them to move in water
Answer:
Photosynthesis consist of two types of reaction 1 light dependent reaction 2 light independent reaction or dark reaction.
Explanation:
light dependent reaction
light dependent reaction or light reaction occur in the thylakoid of granum of chloroplast.During light reaction light energy is absorbed by various pigments of the photosystem and is finally converted into chemical energy.
During light reaction water is split in presence of sunlight to form H+ and OH- ions.The OH- ions releases electron.The released electron is then transported through various electron carriers resulting in the formation of ATP molecule by cyclic photo phosphorylation and NADPH by noncyclic photophosphorylation.
Light independent reaction
Light independent reaction or dark reaction occur in the stroma of chloroplast.The ATP and NADPH that is formed during light reaction is used as 3:2 ratio for per molecule of glucose production.
Answer:
cytoplasm
Explanation:
A cell can be thought of as a "factory," with different departments each performing specialized tasks. A cell's plasma membrane regulates what enters or leaves the cell.
Answer:
The level of compaction in Eukaryotes from naked DNA to the most compact is:
d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome
Explanation:
As we know that the
- Diameter of DNA is 2 nm.
- Diameter of nucleosome is 11 nm.
- Diameter of solenoid is 30 nm.
- Diameter of looped chromation is 300 nm
- Diameter of meta-phase chromosome is 1400 nm
All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.
