Answer 1

29,b-2

Chloroplast has two membranes- the outer and the inner membrane. It is called as chloroplast envelope. The outer membrane is more permeable than the inner ones to small molecules.

30, b-2

Mitochondria has two membranes. The outer membrane covers the organelle completely whereas the inner membrane folds inside making a layer named as cristae.

31, b-grana.

The stack of thylakoids arranged like a stack of coin is called as stroma.it helps in trapping light energy from sun.

32, false

The energy molecules such as ATP and NADPH produced in light dependent reactions is used to drive the light independent reaction called Calvin cycle.

33, true

The ATP and NADPH provides generated from light reactions provides energy to convert the carbon in CO2 to sugar molecule- Glyceraldehyde 3 phosphate. This process is called as carbon fixation or the Calvin cycle.

34, a-water

Photosystem-II gets electron by splitting of water molecules

35, b-RuBisCO catalyses the process of carbon fixation which is a process of conversion of CO2 into stable sugar compound.

36, c-thylakoid membrane

Light reactions takes place in thylakoid membrane of the chloroplast whereas light independent reaction takes place in stro
