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 atmospheric layer contains the highest concentration of ozone?
The ozone layer is a protective layer in Earth's atmosphere that protects Earth's surface from the strongest UV rays that come off the sun. The vast majority of the ozone layer is found in the stratosphere.
Which surface of the leaf upper or lower contains the most chlorophyll Explain why?
The upper surface of the leaf typically contains more chlorophyll than the lower surface. This is because the upper surface is exposed to more sunlight, which is essential for photosynthesis. Chlorophyll absorbs light energy, and having a higher concentration on the top maximizes light capture, enhancing the plant's ability to produce food. Additionally, the lower surface often has more stomata for gas exchange, which doesn't require as much chlorophyll.
Palisade cells are adapted to their function by having lots of chloroplasts. yes or no?
Yes, palisade cells are adapted to their function by having a high concentration of chloroplasts. This adaptation allows them to efficiently capture sunlight for photosynthesis, maximizing the plant's ability to produce energy. Additionally, their elongated shape helps to increase surface area and light absorption.
Which principal energy level has a maximum of three sub levels?
The second principal energy level has a maximum of three sublevels. These sublevels are s, p, and d, with s having 1 orbital, p having 3 orbitals, and d having 5 orbitals.
What that moves over earths surface when it rains is called?
Water which moves over the earths surface after having precipitated (rain, snow, etc) is known as runoff. Most rivers get the majority of their water from precipitation runoff.
How does weathering and erosion shape earths surface?
Weathering breaks down rocks into smaller pieces, while erosion transports these pieces to new locations. Over time, these processes can create features like valleys, canyons, and coastlines, shaping the Earth's surface.
What is water that moves over Earth's surface when it rains called?
Water which moves over the earths surface after having precipitated (rain, snow, etc) is known as runoff. Most rivers get the majority of their water from precipitation runoff.
Having a lower concentration of solutes?
Osmosis
What device can you use for having maximum bandwith in a PC connected in a network?
Router having maximum bandwidth in network. and in network fiberoptic cable having max bandwidth for data travaling
What is a reason for Arkansas having multiple seasons?
the tilt of the earths axis
What physical properties are being exploited in evaporation?
Evaporation exploits the physical property of molecules having different energies, resulting in some molecules having enough energy to break free from the liquid's surface and form a gas. Additionally, evaporation takes advantage of the tendency of molecules to move from an area of higher concentration (liquid phase) to an area of lower concentration (gas phase).
Having the same solute concentration as another solution?
Isotonic
Which is the substance having maximum mass in the world?
galaxy.................it having 10 power 55kg mass........
What are the adaptation that speed up diffusion in living organisms?
Chemotaxis - Natural movement of cells along a concentration gradient, either away or towards chemical stimulus Diffusion distances are short Concentration Gradients are maintained Diffusion surfaces are large
What is a curved surface?
A surface having no equivalent point at any plane
Why is red light having maximum wavelength?
Because red light has minimum frequency and thus it has maximum wavelength.
