What is the number of chloroplasts in palisade mesophyll?
Palisade mesophyll cells typically contain a high number of chloroplasts, often ranging from 40 to 100 chloroplasts per cell. This abundance maximizes the cells' ability to capture light for photosynthesis, as they are located just beneath the upper epidermis of leaves where light intensity is greatest. The exact number can vary depending on the plant species and environmental conditions.
Do fungus have chloroplasts?
No, fungi do not have chloroplasts. Chloroplasts are found in plants and algae, where they are responsible for photosynthesis. Fungi obtain their nutrients from other sources and do not perform photosynthesis.
What cell part do chloroplasts lie?
Chloroplasts live in plant and algal cells. Their main role in the ecosystem is to conduct photosynthesis by capturing the energy from the sunlight for storage.
How do the walls of epidermal cells compare with those of palisade cells?
Epidermal cells have thin, flexible cell walls that allow for gas exchange and protection of the underlying tissues, while palisade cells, found in the mesophyll of leaves, have thicker and more rigid walls to provide structural support and maximize light absorption for photosynthesis. Additionally, palisade cells are tightly packed to optimize light capture, whereas epidermal cells are more loosely arranged and often coated with a waxy cuticle to reduce water loss. Overall, the differences in wall structure reflect their distinct functions in plant physiology.
What is the best explanation of both chloroplasts and mitochondria cells?
Chloroplasts and mitochondria are organelles found in plant and animal cells, respectively, that play crucial roles in energy conversion. Chloroplasts are responsible for photosynthesis, converting sunlight, carbon dioxide, and water into glucose and oxygen, primarily in plant cells. Mitochondria, often referred to as the powerhouse of the cell, generate adenosine triphosphate (ATP) through cellular respiration, using nutrients and oxygen. Both organelles have their own DNA and are believed to have originated from ancient symbiotic bacteria, highlighting their evolutionary significance.

The primary function of the palisade mesophyll?
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 leaves 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 (used in photosynthis). The spongy mesophyll are usually ball-shaped with large intercellular spaces, but usually contains fewer chloroplasts than the palisade cells. The palisade mesophyll, bundle sheath and spongy mesophyll are known as the ground parenchyma. There is a system of air spaces which communicate with the air chambers behind the stomata (which are like our pores). Since the mesophyll cells contain chloroplasts the tissue is also referred to as chlorenchyma . To sum it up, the functions of the Mesophyll are......... * The palisade cells are responsible for photosynthesis because they contain chloroplasts. * The spongy mesophyll, together with the intercellular air spaces, allow for the interchange of gases.
Do fungus have chloroplasts?
No, fungi do not have chloroplasts. Chloroplasts are found in plants and algae, where they are responsible for photosynthesis. Fungi obtain their nutrients from other sources and do not perform photosynthesis.
What is a pallisade?
A palisade is a type of fence or barrier made up of stakes or wooden posts, often used for defense or enclosure. It can also refer to a row of trees or shrubs planted closely together for privacy or aesthetics. In a botanical context, palisade refers to a layer of cells in plant leaves that are rich in chloroplasts, facilitating photosynthesis. Overall, the term conveys the idea of protection or structure, whether in architecture, landscaping, or biology.
What cell part do chloroplasts lie?
Chloroplasts live in plant and algal cells. Their main role in the ecosystem is to conduct photosynthesis by capturing the energy from the sunlight for storage.
What is a paliside?
it is a cell found in plants.
How often do you feel pelvic pain during pregnancy?
It will increase as the days draw nearer for the due day.
What is a palisade flower arrangement?
A palisade flower arrangement is a floral design characterized by a vertical, structured layout that resembles a row of tall, upright flowers. This arrangement typically features flowers placed tightly together, often in a linear fashion, creating a sense of height and elegance. The palisade style is commonly used for formal occasions and can incorporate a variety of flower types and colors to enhance visual impact.
How do the walls of epidermal cells compare with those of palisade cells?
Epidermal cells have thin, flexible cell walls that allow for gas exchange and protection of the underlying tissues, while palisade cells, found in the mesophyll of leaves, have thicker and more rigid walls to provide structural support and maximize light absorption for photosynthesis. Additionally, palisade cells are tightly packed to optimize light capture, whereas epidermal cells are more loosely arranged and often coated with a waxy cuticle to reduce water loss.

What does a labeled guard cell look like?
A labeled guard cell typically contains a nucleus, chloroplasts, and a distinct shape that resembles a bean or kidney. These specialized cells are found in pairs surrounding stomata on plant leaves and regulate gas exchange and water loss through their opening and closing. The labels often point out key structures such as the nucleus or chloroplasts.
Why can't you see chloroplasts under microscope?
Chloroplasts are very small and transparent structures within plant cells, making them difficult to observe under a light microscope without staining. Additionally, they are easily disrupted during the preparation process for microscopy. Special techniques, such as electron microscopy, are often needed to visualize chloroplasts with detail.
What organ does photosynthesis?
Photosynthesis takes place primarily in the chloroplasts of plant cells, which are often referred to as the "organs" responsible for carrying out photosynthesis within the plant. Specifically, the chloroplasts are the site where light energy is converted into chemical energy in the form of glucose.
