The upper surface of a dicot leaf is typically darker than the lower surface due to the higher concentration of chlorophyll in the palisade mesophyll, which is more abundant on the upper side. This structure is optimized for light absorption, maximizing photosynthesis. In contrast, the lower surface has more air spaces and stomata for gas exchange, leading to a lighter coloration. Additionally, the presence of protective features like a waxy cuticle may also contribute to the appearance of the lower surface.

Difference between dicots and monocots in terms of stomata number and distribution?
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
Where are most of the stomates found in the dicot leaf?
Underside the leaf to conserve water, because if they are exposed to the sun, they can lose water very easily. This prevents excessive transpiration.
How does lower epidermis adapt to do it job in the leaf?
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
Why do dicots have palisade parenchyma on their leaves?
Dicot leaves are generally dorsiventral, having palisade cells on the upper surface of the leaf which receives light, and lower surface has spongy parenchyma for gaseous exchange with several stomatal pores. The palisade cells are columnar with large number of chloroplasts to trap maximum light.
What could explain the darker appearance of moons and rings in the outer solar system?
The darker appearance of moons and rings in the outer solar system could be due to the presence of darker, reddish organic substances created by radiation processing of materials on the surface. Additionally, the lower sunlight levels in the outer solar system could contribute to the darker appearance as well. These factors combine to create a darker and more complex composition for objects in the outer solar system.

Which part of leaf is dorsal?
The upper side of a leaf is referred to as the dorsal side. It is also known as the adaxial surface and is typically darker in color compared to the lower side, which is called the ventral side or abaxial surface.
Why is the colour of the upper surface of the lily a darker green than the lower surface?
Because light receiving part has more chloroplasts in the palisade cells hence the upper part is darker green.
Why can't you see anything in ganache mine on harvest moon tree of tranquility?
The lower you go the darker it gets. After a while it will get lighter the more low you get.
Where are most of the stomates found in the dicot leaf?
Underside the leaf to conserve water, because if they are exposed to the sun, they can lose water very easily. This prevents excessive transpiration.
Why do sunspots appear darker than the surrounding surface of the sun?
Sunspots appear darker than the surrounding surface of the sun because they are cooler regions on the solar surface, with temperatures around 3,000 to 4,500 degrees Celsius compared to the surrounding areas, which can reach about 5,500 degrees Celsius. The lower temperature results in reduced brightness, making them appear dark in contrast to the hotter, brighter photosphere. Additionally, the magnetic activity associated with sunspots inhibits the convective flow of heat, further contributing to their darker appearance.

What rain clouds look like?
grey darker and lower
What color of the rainbow has the lower frequency?
it is red becaude it is darker
Sunspots are regions of?
magnetic activity on the sun's surface that appear darker than their surroundings due to their lower temperature. They are temporary phenomena that occur in cycles and can affect space weather on Earth.
What is a dorsiventral leaf?
the anatomy of isobilateral and dorsiventral leaf is similar in many ways. however,it shows the following characteristic differences: 1. In monocot leaf the stomata are present on both the surfaces of epidermis 2. Mesophyll is not differentiated into palisade and spongy chlorenchyma 3. In upper epidermis of monocot leaf bulliform cells occur at regular interval which helps in reducing the rate of transpiration 4. the vascular bundle of dicot leaf is covered with parenchymatous bundle sheath and vascular bundle of monocot leaf are surrounded by sclerenchymatous and parenchymatous sheath.
