Photosynthesis: The Basics
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 photosynthesis takes place in the leaves? Photosynthesis primarily happens in green leaves (not colorful autumn leaves). Leaves are ideal for photosynthesis because they are usually broad and flat, giving plenty of surface area for light to be absorbed. They are also thin, which means diffusion of gases such as carbon dioxide can happen quickly.
Similarly, Which part of the leaf does most photosynthesis take place? 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.
Where does photosynthesis and cellular respiration take place?
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.
Does photosynthesis occur in the stroma?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.
Does photosynthesis take place only in green leaves?
photosynthesis take place only in green plant because they are the only living things which use carbon dioxide , chlorophyll , sunlight for making their food. Photosynthesis can only take place in green plants , because they contain a special green pigment (substance) called chlorophyll on its surface.
Why does photosynthesis only take place in the chloroplast? Chloroplasts trap the solar energy from the sun and thus this energy is required by plants to make their own food and the main thing chlorophyll is present only in chloroplasts . So photosynthesis Takes place inside chloroplast.
Does photosynthesis only occur in plants? Photosynthesis is seen in plants, algae and some microbes. So, plants are not the only ones carrying out photosynthesis. The basic requirement of photosynthesis is sunlight, water, carbon dioxide and the chlorophyll contained in chloroplasts. Plants fulfil all these requirements, hence photosynthesis is seen in plants.
What role do the stomata play in transpiration and photosynthesis?
The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen.
Which tissue takes part in photosynthesis? All green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in the leaves. The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis.
Which substances are inputs in photosynthesis?
In photosynthesis, water, carbon dioxide, and energy in the form of sunlight are inputs, and the outputs are glucose and oxygen.
Where do the reactants for photosynthesis come from? Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.
What are the end products of photosynthesis process taking place in plants?
Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is a process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
In which part of a chloroplast does photosynthesis occur quizlet?
They produce the source of chemical energy for themselves and for other organisms. In what two parts in a chloroplast does photosynthesis take place? The Grana and The Stroma.
What is the process of photosynthesis in chloroplast? chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
Does photosynthesis occur only in all plants and how does photosynthesis take place in plants with non green leaves explain?
Photosynthesis occurs in those plants as well, which have non-green leaves. Chlorophyll is present in lesser quantity and other pigments mask the green colour of chlorophyll, so they do not appear green but perform photosynthesis.
Can photosynthesis take place without chlorophyll?
If plants require chlorophyll to produce energy from sunlight, it’s logical to wonder if photosynthesis without chlorophyll can occur. The answer is yes. … Plants that have purplish-red leaves, like Japanese maples, use the photopigments that are available in their leaves for the process of plant photosynthesis.
In what part of the leaf does the most photosynthesis take place Why? 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 are the two reactions that take place during photosynthesis?
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.
Does photosynthesis occur in leaves only if no what are the other parts that are capable of carrying out photosynthesis justify? Explanation: Photosynthesis can be carried out by any green parts of the plant. These green part contain chlorophyll the pigment that carries out photosynthesis in presence of sunlight and carbon dioxide.
Are stomata?
Stomata are the tiny openings present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis.
What are the two reactions that take place in the process of photosynthesis? The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.
