Plants perform photosynthesis because they need to prepare their food and during night time they respire to break down the prepared food. In seeds food is already prepared and stored in the cotyledons and a seed only needs to break it down(so they respire producing co2). this co2 increases the temperature in the flask.

We could draw an imaginary line from C perpendicular to EC and parallel to AB dividing angle y into 2 parts and marking the point as R. Now RCA = CAB =22 as they are alternate interior angles & RCE = ECD = 90. So angle y will be equal to 90+22=112.

We could draw an imaginary line from D in a straight line till it meets line segment AB and mark the point as Q.Since we know that the sum of the 2 interior opposite angles is equal to the opposite exterior angle, so 45 + 50 = angle AQD = 95.Using the same property 35 + 95 = x = 130.
