In the spongy and palisade mesophyll, due to the large amounts of chloroplasts.
chloroplast i think..
Leaf cells that contain the most chloroplasts are typically found in the mesophyll layer, specifically in the palisade mesophyll. These cells are located just beneath the upper epidermis of the leaf and are tightly packed to maximize light absorption for photosynthesis. The abundance of chloroplasts in these cells allows for efficient conversion of light energy into chemical energy, contributing significantly to the plant's overall photosynthetic capacity.
Most photosynthesis in a leaf occurs in the mesophyll cells, found in the middle layer of the leaf. Specifically, the chloroplasts within the mesophyll cells are responsible for conducting photosynthesis by capturing light energy and converting it into chemical energy in the form of glucose.
Brassica napus is a C3 plant. It utilizes the C3 photosynthetic pathway, which is the most common photosynthetic pathway in plants.
The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.
The upper part of the leaf is were the most sunlight hits the leaf, so due to adaptations, chloroplasts moved to the upper parts of leaves.
The palisade mesophyll is responsible for photosynthesis, as it contains chloroplasts and is where most of the photosynthetic activity in a leaf takes place. It is situated near the upper epidermis to receive sunlight for photosynthesis. Additionally, the palisade mesophyll cells are tightly packed together to maximize light absorption.
In vascular plants with leaves, the upper or sunward sides of the leaves will have the most photosynthetic activity. In other plants, such as kelp or cacti, the sunward-facing surfaces of the plant will have the most photosynthetic activity.
Chlorophyll is the major photosynthetic pigment in plants. It absorbs light energy, which is then used to convert carbon dioxide and water into glucose and oxygen during the process of photosynthesis.
Photosynthetic cells are mainly on the upper side of a leaf because they can receive more sunlight there, which is essential for photosynthesis. This positioning maximizes the absorption of sunlight for energy production and allows the plant to efficiently convert carbon dioxide into carbohydrates. Placing the photosynthetic cells on the upper side also helps to reduce water loss through transpiration.

The majority of a leaf is composed of mesophyll tissue, which contains two types: palisade mesophyll and spongy mesophyll. Palisade mesophyll is located near the upper surface of the leaf and is responsible for most of the photosynthesis, while spongy mesophyll is found below and aids in gas exchange and nutrient storage.
Lichen is the product of a symbiotic relationship between a fungus and a photosynthetic organism, usually a photosynthetic bacteria or algae. The photosynthetic organism gains a place to live and protection. Most of the organisms that live as part of a lichen need a moist environment and cannot usually live in the areas that lichen can grow; The fungi allows the photosynthetic organism to remain moist. The fungi gains a source of energy from the photosynthetic organism. The photosynthetic organism produces sugars using solar energy which are used by the fungi.
Phytoplankton form the foundation for most marine life food webs. Also they are responsible for half the photosynthetic activity on earth. My source was : http://www.ehow.com/about_5414740_importance-phytoplankton.html
