In what cells of the leaf does photosynthesis take place?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Which layer of cells in the leaf is responsible for most photosynthesis?
palisade mesophyll layerThe palisade mesophyll layer is just below the upper epidermis. It is made up of closely-packed, elongated cells. These cells contain chloroplasts . They perform most of the photosynthesis.
Which part performs the photosynthesis?
Complete answer: Leaves perform photosynthesis in plants. Leaves have mesophyll cells that contain chloroplasts in them. The chloroplast is a double-membraned organelle that contains the green-coloured pigment called chlorophyll which absorbs light from the sun and performs photosynthesis.
What cell structures are most important to photosynthesis?
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.
Which tissue carries out the largest amount of photosynthesis?
The mesophyll is the primary location for photosynthesis and is divided into two layers, the upper palisade layer and the spongy mesophyll layer.
Where is the mesophyll located?
leafMesophyll 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 ...
Which part of the leaf is responsible for photosynthesis?
Cells in the mesophyll of the leaf have numerous chloroplasts. In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis.
What is the role of the leaves in photosynthesis?
stoma). They play a central role in photosynthesis, allowing carbon dioxide to enter the leaf and oxygen to exit the leaf.
What type of tissue does a plant have?
Certain types of plants (dicots and some net-veined monocots) have two different types of mesophyll tissue. Palisade mesophyll cells are densely packed together, whereas spongy mesophyll cells are arranged more loosely to allow gases to pass through them. Palisade mesophyll cells also have more chloroplasts than spongy mesophyll cells.
What are the structures that transport water from the roots to the cells that carry out photosynthesis?
They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis. 1. The plant’s vascular tissues—xylem and phloem—transport water to the leaves and carry glucose away from the leaves. Anyone who cares for plants could probably tell you that pouring water directly onto the leaves isn’t ...
How do plants absorb water?
Plants absorb water from the soil, using their roots. As you probably already know, water is necessary for photosynthesis, which primarily occurs in the plant’s leaves. You might wonder how the water gets from the roots into the leaves, and the answer is through the plant’s vascular system! Just like the veins and arteries ...
What are the most important parts of a plant?
Leaves, and the structures they contain, play key roles in photosynthesis. When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them.
Where do sugars move in a plant?
Once photosynthesis has occurred, the produced sugars move through the phloem to other parts of the plant to be used in cellular respiration or stored for later.
