What is the main function of photosynthetic tissue?
The plant body is divided into several organs: roots, stems, and leaves. The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy.
What is the photosynthetic tissue of a leaf?
Mesophyll cells The mesophyll is located between the upper and lower layers of the leaf epidermis, and is mostly made up of parenchyma (ground tissue) or chlorenchyma tissue. The mesophyll is the primary location for photosynthesis and is divided into two layers, the upper palisade layer and the spongy mesophyll layer.
What are the functions of xylem and phloem in leaf?
Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
How do the photosynthetic products enter the leaf?
Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata.
Why is an aquatic plant used in the experiment?
Answer: to prove that oxygen is necessary for the photosynthesis. Because hydrilla is a small plant and hence easy to handle and also it is a aquatic plant so it is able to breath in water whereas land plants are not.
What is the function of Collenchyma?
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
What is Collenchyma function?
What is the function of phloem tissue?
Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation.
What does a photosynthetic tissue do?
The photosynthetic tissue of a leaf, located between the upper and lower epidermis. The tissues of a leaf that are located in between the layers of epidermis and carry on photosynthesis, consisting of the palisade layer and the spongy parenchyma . Most mesophyll cells contain chloroplasts.
Which organisms use photosynthesis?
Photosynthetic organisms, also known as photoautotrophs, are organisms that are capable of photosynthesis. Some of these organisms include higher plants, some protists (algae and euglena ), and bacteria.
Where are photosynthetic membranes found?
Photosynthesis occurs in the chloroplasts; specifically, in the grana and stroma regions. The grana is the innermost portion of the organelle; a collection of disc-shaped membranes, stacked into columns like plates. The individual discs are called thylakoids.
What are photosynthetic cells?
Photosynthesis is a process found in plant cells which converts light energy into chemical energy in the form of sugars that the plant can store and use at any time. Photosynthesis takes place in the chloroplasts , an organelle only found in plant cells, and consists of two parts: the light dependent reaction,…
