Can some help me with this- Chloroplast-
1) Main function I the cell?
2) Found in which cells?
3) Structure determines function?
4) Chemical formula for cellular respiration?

Mitochondria-
1) Structure determines function?

Chloroplast

1. Help in photosynthesis

2.Plant cell

3.It is where chlorophyll is formed and this chlorophyll traps sunlight for photosynthesis.

4. C6H12O6 + 6O2> 6CO2 + 6O2 + Energy

Mitochondria

1.It posses it own DNA and also has a big surface area which makes it possible to generate more energy then supply them in the cells.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

your answer is going to be physical weathering
