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.
What else can I help you with?
Why are the photosynthetic cells mainly on the upper side of a leaf?
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.
What are cells between the upper and lower epidermis of the leaf called?
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.
What are the loosely packed photosynthetic cells in the leaf called?
Thylakoids. Stacks of these are called granna.
What kind of cells in the leaf carry out photosynthetic activity?
spongy and pallisade parenchyma
True or false when a leaf's upper epidermal cells open carbon dioxide oxygen and water vapor escapes?
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?
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.
What is the photosynthesis cell called?
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?
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.
Where in a leaf would you expect to find palisade cells?
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.
What leaf cells are tightly packed and trap the energy in sunlight?
chlorophyll
What are the cells in the leaves that have the most chloroplasts and are tightly packed?
The cells in the leaves that contain the most chloroplasts and are tightly packed are called palisade mesophyll cells. These cells are located just beneath the upper epidermis of the leaf and are primarily responsible for photosynthesis due to their high chloroplast density. Their arrangement allows for maximum light absorption, which is essential for the photosynthetic process.
What is a photosynthetic organ of the plant?
The primary photosynthetic organ of a plant is the leaf.
