branch are usually narrow and slope & magnetism that are tiny and slope have a tiny bottom perimeter ->  leaves usually have a large surface area  quality that are more exposed to shadow are realsome for absorbing shadow & a tiny bottom perimeter is more exposed to shadow ->  objects with a large surface area are ideal for absorbing sunlight  leaves usually have a large surface area & objects with a large surface area are ideal for absorbing sunlight ->  leaves are ideal for absorbing sunlight  leaves are ideal for absorbing sunlight & a branch is a whole of a yellow vegetable ->  a leaf is a part of a green plant that is ideal for absorbing sunlight  a leaf is a part of a green plant that is ideal for absorbing sunlight & a vegetable requires shadow for sun -> a leaf absorbs sunlight to perform photosynthesis
