What is the main tissue of photosynthesis?
The major tissues are mesophyll, veins, and epidermis. Mesophyll makes up most of the leaf’s interior. This is where photosynthesis occurs. Mesophyll consists mainly of parenchymal cells with chloroplasts.
What is the name of the main photosynthetic tissue in a leaf?
palisade mesophyll
The part of a leaf where most photosynthesis takes place is the palisade mesophyll , also called the palisade parenchyma.
What tissue is responsible for photosynthetic output?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
What is palisade mesophyll in biology?
: a layer of columnar cells rich in chloroplasts found beneath the upper epidermis of foliage leaves. — called also palisade mesophyll, palisade parenchyma, palisade tissue. — compare spongy parenchyma.
Which two tissues of a leaf are photosynthetic?
This tissue is called the mesophyll, meaning “middle leaf,” and comes in two flavors: the palisade mesophyll (sometimes called palisade parenchyma) and the spongy mesophyll. Most photosynthesis takes place in the palisade mesophyll, which is conveniently located at the top of the leaf just under the epidermis.
Which part of a leaf is most photosynthetic?
mesophyll
1: Structure of a leaf (cross-section): Photosynthesis takes place in the mesophyll. The palisade layer contains most of the chloroplast and principal region in which photosynthesis is carried out.
What is mesophyll leaf?
Mesophyll is the internal ground tissue located between the two epidermal cell layers of the leaf; and is composed of two kinds of tissues: the palisade parenchyma, an upper layer of elongated chlorenchyma cells containing large amounts of chloroplasts; and the spongy parenchyma, a lower layer of spherical or ovoid …
What is spongy layer?
Main Entry: spongy layer. Function: noun. : a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis — called also spongy parenchyma, spongy tissue.
Are epidermal cells photosynthetic?
The guard cells are bean-shaped in surface view, while the epidermal cells are irregular in shape. The guard cells contain chloroplasts, so they can manufacture food by photosynthesis (The epidermal cells of terrestrial plants do not contain chloroplasts)
Which of the following is a Xerophyte?
So, the correct answer is ‘Opuntia’.
Where do you find more photosynthetic activity in a leaf?
ANSWER: More photosynthetic activity occurs in upper lamina of the leaf in order to attract more sunlight. EXPLANATION: The palisade mesophyll cell contain more chloroplasts thus being the area of photosynthesis.
