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.
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.
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
Thylakoids. Stacks of these are called granna.
spongy and pallisade parenchyma
True. When a leaf's upper epidermal cells, specifically through structures called stomata, open, carbon dioxide enters the leaf for photosynthesis, while oxygen and water vapor can escape as byproducts of this process. This gas exchange is crucial for maintaining the plant's respiratory and photosynthetic functions.
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.
the main photosynthetic cells in a leaf are the palisade cells, they contain many chloroplasts which actually carry out photosynthesis.
The main photosynthetic area of a leaf is composed of cells called mesophyll cells, specifically the palisade and spongy mesophyll cells. These cells contain chloroplasts, which house chlorophyll and are responsible for capturing light energy to drive photosynthesis. The arrangement of these cells maximizes the leaf's surface area exposed to light for efficient photosynthesis.
Palisade cells are typically found in the upper layer of a leaf called the palisade mesophyll. They are located directly beneath the upper epidermis and are responsible for carrying out photosynthesis due to their high concentration of chloroplasts.
chlorophyll
The primary photosynthetic organ of a plant is the leaf.
In Animals,The Parenchyma are the functional parts of an organ in the body, this is in contrast to the stroma, which refers to the structural tissue of organs, namely, the connective tissues.In Plants,Parenchyma cells are thin walled cells of the ground tissue that make up most of non woody structures.The cells in the leaf constitute the mesophyll (photosynthetic parenchyma cells that lie between the upper and lower epidermis layers of a leaf) they are responsible for photosynthesis and allow for the inter change of gases.
