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.
The vast majority of chloroplasts found in a leaf are located where?
The vast majority of chloroplasts in a leaf are found in the mesophyll cells, specifically in the palisade and spongy mesophyll layers. These cells contain chloroplasts that are responsible for photosynthesis, where they capture light energy and convert it into sugars for the plant's energy.
How are leaves adapted to its function?
Leaves are adapted to their function in several ways: Because leaves photosynthesis it needs water and carbon dioxide to complete the rection. They have board leaves giving them a big surface area for light to fall on They contain chlorophyll in the chloroplast to absord the sunlight They have air spaces that allow carbon dioxide to get to the cells, and oxygen to leave them be diffusion They have veins, which bring plenty of water to the cells of the leaves (these are called xylem) Hoped this helped :)
Why do you think the palisade mesophyll cells are columnar in shape?
Palisade mesophyll cells are columnar in shape because they are packed tightly together to maximize light absorption for photosynthesis. The columnar shape allows for more chloroplasts to be present near the cell surface, optimizing the capture of light energy.
Why all plant don't have chloroplasts?
Only cells which can get sunlight have chloroplasts. There is no purpose for others having it
What are the advantages of having no chloroplast in the spongy mesophyll cells?
What would be the advantages to having no chloroplasts in the cells of the spongy mesophyll? Fewer chloroplasts in the spongy mesophyll because most of the light energy is absorbed by the chloroplasts of the palisade mesophyll. ... They waxy cuticle keeps water inside the leaf cells.

Adaptation of palisade cells?
A palisade cell is adapted to its function because it has lots of chloroplasts, which contain chlorophyll, an essential substance in photosynthesis and they are at the top of the leaf so they can absorb as much light energy as possible.It also has a regular shape so you can fit more in, in a smaller space

1 Is there any advantage to a leaf in having palisade mesophyll on the upper half and spongy mesophyll on the lower half?
Yes, having palisade mesophyll on the upper half of the leaf allows for more efficient light absorption and photosynthesis due to its packed arrangement of chloroplasts. Spongy mesophyll on the lower half facilitates gas exchange and storage of substances like water and nutrients, contributing to overall leaf function. This differentiation optimizes the leaf's adaptation to its environment.
What is the function of palisade mesophyll cell?
Palisade mesophyll cells in plants are responsible for photosynthesis, as they contain a high number of chloroplasts. Their elongated shape allows them to be packed tightly together, maximizing their exposure to light for efficient photosynthesis. They are located in the upper layer of the leaf where light penetration is highest.
Why does a palisade cell have a cell wall?
Really all cells have a cell wall, this gives them soport and protection from bacteria, only having the virus as a threat
What is the palisade mesophyll?
Palisade cells are cells found within the mesophyll in leaves of dicotyledonous plants. They contain chloroplasts, which convert the energy stored in photons to chemical energy through photosynthesis, which is made up of two main stages; thelight-dependent reactions and light-independent reactions. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells, irregularly-shaped cells that having many intercellular spaces to allow the passage of gases, such as the intake of carbon dioxide for photosynthesis to take place. The stomata is the way in which these gases are exchanged, as well as the transpiration of water from the xylem, either by the apoplast or symplast pathway. Palisade cells are positioned towards the upper surface of the leaf and contain the largest number of chloroplasts per cell in plants. This makes them the primary site of photosynthesis in a plant's leaves. They have a very large surface area in order for them to absorb more light during photosynthesis

How are male gametes adapted to their function?
the sperm is the male sex cell and it is adapeted by having a pointed head for speed, and a long tail to help it swim.
