Which type of plant tissue contains cells with many chloroplasts?
The type of plant tissue that contains cells with many chloroplasts is called mesophyll. Mesophyll is primarily found in the leaves and is responsible for photosynthesis. It consists of two layers: the palisade mesophyll, which has tightly packed cells with numerous chloroplasts for efficient light absorption, and the spongy mesophyll, which has more air spaces to facilitate gas exchange.
How many layers does the mesophyll have?
The mesophyll has two layers. The outermost layer is the palisade layer that is made of tightly packed chloroplasts, and the innermost layer is the "spongy layer" that has air between its cells.
How are the two types of mesophyll found in a leaf specialized for photosynthesis?
The two types of photosynthetic mesophyll are -- (i) Palisade cells which are vertically elongated cylindrical cells and (ii) Spongy mesophyll cells that are spherical green cells.
What physical process takes place on the surface of the spongy mesophyll cells?
On the surface of the spongy mesophyll cells, gas exchange occurs primarily through small openings called stomata. These cells facilitate the diffusion of carbon dioxide into the leaf for photosynthesis and the release of oxygen as a byproduct. Additionally, the spongy mesophyll's air spaces allow for the movement of water vapor, contributing to transpiration. This process is essential for maintaining the plant's internal water balance and overall health.
What is a leaf layer that contains air spaces?
Leaves consist mostly of tissue called mesophyll, which is made up of loosely arranged cells with spaces between them. The spaces are filled with air, from which the cells absorb carbon dioxide and into which they expel oxygen.
What are types of mesophyll cells?
The two main types of mesophyll cells found in plant leaves are palisade mesophyll cells and spongy mesophyll cells. Palisade mesophyll cells are located in the upper layer of the leaf and are specialized for photosynthesis, while spongy mesophyll cells are found beneath the palisade layer and aid in gas exchange and the storage of nutrients.
What are two types of mesophyll?
The two types of mesophyll in plant leaves are palisade mesophyll and spongy mesophyll. Palisade mesophyll is located closer to the upper epidermis and consists of closely packed cylindrical cells that are specialized for photosynthesis. Spongy mesophyll is located beneath the palisade layer and consists of loosely arranged cells with air spaces for gas exchange and moisture retention.
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.

What is the advantage of the spongy mesophyll being loosely arranged instead of being closed?
in between the spongy mesophyll cells, there are air spaces. this allows faster diffusion of CO2 into the leaf. the thin film of moisture on the spongy mesophyll evaporates in the air spaces in the process of transpiration, thus helped in transpiration pull. without the spongy mesophyll being loosely arranged, there would not be air spaces.

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.
What is spongy mesophyll layer?
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
What gives the spongy mesophyll its name?
The spongy mesophyll gets its name due to its porous structure, which resembles a sponge. This layer of tissue, found in the leaves of plants, contains air spaces that facilitate gas exchange, allowing carbon dioxide to diffuse in and oxygen to diffuse out during photosynthesis. The spongy mesophyll's loosely arranged cells maximize the surface area for gas exchange while still providing some structural support to the leaf.
