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).
Why does photosynthesis mostly take place in the leaves?
Photosynthesis, a plant's internal process that converts light energy into food, takes place mostly in the leaves of plants. ... Plants also require carbon dioxide to perform initial reactions, which they absorb through tiny pores located across their leaves and stems.
Where does photosynthesis in the plant mainly take place?
Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen.
What layer of the leaf is the most photosynthetic?
Leaf mesophyll composed of parenchyma tissue. The elongated palisade parenchyma contains the largest number of chloroplasts per cell and is the primary site of photosynthesis in many plants.
In which light photosynthesis takes place faster?
As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After white, we have violet light where photosynthesis occur to a higher extent as it has the shortest wavelength hence has the max energy.
Does photosynthesis occur in all plant cells?
Photosynthesis takes place inside plant cells in small things called chloroplasts . Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen . ... So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
What is photosynthesis class 6th?
Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into chemical energy . Complete Answer: A.
Does photosynthesis happen in stems?
Photosynthesis: The Inside
Photosynthesis primarily takes place in the leaves, with a smaller amount in the stems , and has both a light independent and light dependent process.
What two layers make the leaf?
The tissues of the leaf in between the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be further broken down into two layers, the palisade layer and the spongy layer , both of which are packed with chloroplasts, the factories of photosynthesis.
Which leaf has the most stomata?
Explanation: All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However, the lower epidermis (the underside of the leaf) has more, because it is more often in the shade and so it is cooler, which means evaporation won't take place as much.
What are the pores on the underside of leaves called?
Stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems. Stomata are generally more numerous on the underside of leaves.
In which light photosynthesis is maximum?
In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light . So, the correct answer is, ‘Red light'. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.
In which Colour photosynthesis is minimum?
In the absorption spectrum, it can be shown that red light and blue light are absorbed the most whereas the green light is most commonly reflected. Therefore minimum photosynthesis takes place in green light. So, the correct answer is, ‘Blue and Green light.
Which Colour is best for photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
Does photosynthesis only occur in leaves?
Photosynthesis primarily happens in green leaves (not colorful autumn leaves). ... Leaf cells are full of organelles called chloroplasts, which contain chlorophyll, a pigment that absorbs light. (Chlorophyll absorbs all the red and blue wavelengths of light, but it reflects green wavelengths, making the leaf look green.)
