What are mesophyll?
Mesophyll is the tissue found within the interior of plant leaves, sandwiched between the upper and lower epidermal layers. It is responsible for photosynthesis and consists of two types: palisade mesophyll, which is located near the upper epidermis, and spongy mesophyll, which is found below the palisade layer.
What does the palisade mesophyll do in a leaf?
The palisade mesophyll is responsible for photosynthesis, as it contains chloroplasts and is where most of the photosynthetic activity in a leaf takes place. It is situated near the upper epidermis to receive sunlight for photosynthesis. Additionally, the palisade mesophyll cells are tightly packed together to maximize light absorption.
Is the palisade layer where most photosynthesis in a leaf occur?
Mesophyll tissue forms the bulk of the leaf. It makes up the green tissue of the leaf and consists of thin-walled cells containing chloroplasts (bits that contain the chlorphyll). In most dicot plants, the mesophyll is differentiated into palisade parenchyma and spongy parenchyma. The palisade parenchyma consists of thin-walled cells which are usually cylindrical. These cells contain large numbers of chloroplasts - the organelle used for capturing light and subsequesnt photosysnthesis.The spongy prenchyma, however, contains far fewer chloroplasts, so its main function is not photosynthesis. The spongy parenchyma has an open and net-like structure with large inter-cellular spaces that facilitate gas diffusion. The major function of the spongy parenchyma is the transport of oxygen, carbon-dioxyde and water vapour. It also is involved in the transport of water and the products of photosynthesis, the sugars. The spongy parenchyma is in close connection with the vascular bundles and the palisade parenchyma. When no clear differentiation exists between palisade and spongy parenchyma, the tissue is called mesophyll.Read more: http://wiki.answers.com/Why_is_the_palisade_layer_where_most_photosynthesis_occur#ixzz18UOwDLzu
What kind of tissue forms the majority of leaf?
The majority of a leaf is composed of mesophyll tissue, which contains two types: palisade mesophyll and spongy mesophyll. Palisade mesophyll is located near the upper surface of the leaf and is responsible for most of the photosynthesis, while spongy mesophyll is found below and aids in gas exchange and nutrient storage.
What is located near the epidermis of the stem?
The epidermis of the stem is typically located on the outermost surface of the stem. It serves as a protective layer and is in direct contact with the environment. Just below the epidermis, you would find the cortex or ground tissue of the stem.
Which type of leaf cell contains the most chlorophyll?
chloroplast a subcecullar organelle that contains chlorophyll and enzymes necessary to perform photosynthesis. i hope this helps :)chloroplast a subcecullar organelle that contains chlorophyll and enzymes necessary to perform photosynthesis. i hope this helps :)
What leaf part has many chloroplasts?
the chloroplasts aren't a part of the actual leaf. they are individual organelles found in the cytoplasm of a cell.
Compare the following palisade and spongy mesophylls how do their structural features help them perform their specific roles in the process of food manufacture?
Palisade mesophyll cells are tightly packed, contain many chloroplasts, and are located near the upper leaf surface to maximize light absorption for photosynthesis. Spongy mesophyll cells have air spaces between them to facilitate gas exchange, allowing for efficient transport of gases needed for photosynthesis. The structural features of both cell types are adapted to their specific roles in photosynthesis - palisade mesophyll for light capture and spongy mesophyll for gas exchange.
Ozone layer in the upper atmosphere is diminishing most over what country?
It is diminishing most near the south pole. Australia is the country.
What cells have chloroplasts filled with chlorophyll?
Plant Cell
What do you call the layer of bedrock near earth's surface that forms a continuous shell around earth?
The layer of bedrock near Earth's surface that forms a continuous shell around the Earth is called the lithosphere. This layer includes the crust and upper part of the mantle and is divided into tectonic plates that move and interact with each other.
What is the leaf layer containing most of the chloroplast?
The palisade layer is the leaf layer that contains the majority of chloroplasts. Its location near the upper surface of the leaf allows for efficient absorption of sunlight for photosynthesis. This layer plays a key role in capturing light energy and converting it into chemical energy.
