Which cell type in a leaf performs the most photosynthesis?
1 Answer. The part of a leaf where most photosynthesis takes place is the palisade mesophyll , also called the palisade parenchyma.
Where does photosynthesis take place stem?
Photosynthesis takes place in the chloroplasts, which are tiny parts of cells in the leaves and some parts of the stem. In the cells of all plants, you will find tiny green organelles, called chloroplasts. It is in these important parts of a plant that photosynthesis takes place.
What type of stem can perform photosynthesis?
green stems
Water storage is developed to a high degree in the stems of cacti, and all green stems are capable of photosynthesis.
In which part of a plant leaf does most photosynthesis occur?
mesophyll
Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).
Which part of plant performs photosynthesis?
In plants and algae, photosynthesis takes place in organelles called chloroplasts. A typical plant cell contains about 10 to 100 chloroplasts. The chloroplast is enclosed by a membrane.
In what type of cells do photosynthesis and respiration take place?
Differences between Cellular Respiration and Photosynthesis
| Cellular Respiration | Photosynthesis |
|---|---|
| The entire process occurs in Mitochondria. | The entire process occurs in Chloroplasts. |
| Glucose and oxygen are the reactants of this process. | Carbon dioxide, water and light energy are the reactants of this process. |
Can photosynthesis occur in the stem of a plant?
Photosynthesis occurs mostly in the leaves of the plant; however, it can occur in the stems, but in a minimal proportion.
Is there photosynthesis in stems?
Chlorophyll Fluorescence of Tree Stems. Light is the energy source driving photosynthesis and the signal that regulates plant growth and development. The stems of tree species with chlorophyll can carry out stem photosynthesis (Supplementary Figure 1).
Which part of the plant does photosynthesis occur and why?
Photosynthesis takes place in the green part of plants, which is usually the leaves. The actual site of photosynthesis in a plant is the chloroplast, which is a tiny section of all plant cells, usually located in the mesophyll tissue of plants. All plants contain a green pigment that is called chlorophyll.
What kind of cells have chloroplasts in them?
Chloroplasts are present in the cells of all green tissues of plants and algae. Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants.
What type of cell does it occur in cellular respiration?
Respiration is a metabolic process that takes place within the cells of both plants and animals. In prokaryotes, this process takes place within the cytosol of the cell. In eukaryotes, respiration takes place within the mitochondria of a cell.
Which part of plant take part in photosynthesis?
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.
What does photosynthesis occur in plant cells?
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
Where are the most photosynthetic cells in plants found?
leaves
Photosynthetic cells are found mainly in the leaves of plants and may have thousands of chloroplasts. Chloroplasts are double-membrane organelles with a smooth outer membrane and an inner membrane folded into disk-shaped sacs called thylakoids.
Does cellular respiration occur in all cells?
Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs. All of them catabolize glucose to form ATP.
Why does photosynthesis occur in the mesophyll?
Photosynthesis and the Leaf The process of photosynthesis occurs in a middle layer called the mesophyll. The gas exchange of carbon dioxide and oxygen occurs through small, regulated openings called stomata (singular: stoma ), which also play a role in the plant’s regulation of water balance.
