name the cells of leaf where photosynthesis takes place?

Answer 1

The mesophyll is the leaf tissue where most of the chloroplasts are found and photosynthesis takes place. The mesophyll is differentiated into the palaside mesophyll and teh spongy mesophyll.

The palaside mesophyll is made up of one or more layers of narrow, elongated parenchyma cells; these cells have a higher concentration of chloroplasts, and therefore these are the cells in which most of the photosynthesis takes place.

----
Of course - photosynthesis takes place in *all* the cells which have chloroplasts. But I don't think that is what this question is about.

Answer 2

Mainly photosynthesis takes place in the palasede mesophyly. This is becouse chloroplasts are mainly concentrated in the palased mesophyl.
Morover photosynthesis takes in other cells of the leaf eg, spongy mesophyl, and guard cells.

Answer 3

In leaf mesophyll tissues are present which are sandwiched between two layres of upper and lower epidermis . There are two diffrent shaped cells in mesophyll tissues. The one lying adjacent to upper epidermis are called palisade mesophyll cells as they from a continuous layer beneath upper epidermis.
The other ones are called spongy mesophyll tissues for having air spaces betwenn them. They donot occur in the form of a continous layer as that of palisade cells.
These two kinds of mesophyll cells contain enormous number of chloroplasts , hence they are the site of photosynthesis in leaf.

Answer 4

chloroplast is not a cell it an organule inside the cell and there is where the photosynthesis takes place

Answer 5

The Chloroplast

Answer 6

photosynthesis takes place in chloroplasts...which contain chlorophyll pigment,which is necessary for photosynthesis.misophyll cells of the leaf contain maximum number of chloroplasts...it is the main site of photosynthesis.

Answer 7

Most plants are photoautotrophs, which means that they are able to synthesize food directly from inorganic compounds using light energy -for example the sun, instead of eating other organisms or relying on nutrients derived from them. This is distinct from chemoautotrophs that do not depend on light energy, but use energy from inorganic compounds.

The energy for photosynthesis ultimately comes from absorbed photons and involves a reducing agent, which is water in the case of plants, releasing oxygen as a waste product. The light energy is converted to chemical energy (known as light-dependent reactions), in the form of ATP and NADPH, which is used for synthetic reactions in photoautotrophs. Most notably plants use the chemical energy to fix carbon dioxide into carbohydrates and other organic compounds through light-independent reactions. The overall equation for carbon fixation (sometimes referred to as carbon reduction) in green plants is

n CO2 + 2n H2O + ATP + NADPH → (CH2O)n + n O2 + n H2O,
where n is defined according to the structure of the resulting carbohydrate. However, hexose sugars and starch are the primary products, so the following generalised equation is often used to represent carbon reduction.

Carbon Dioxide + Water + Light energy → Glucose + Oxygen + Water

6 CO2 + 12 H2O + ATP + NADPH → C6H12O6 + 6 O2 + 6 H2O
More specifically, carbon fixation produces an intermediate product, which is then converted to the final hexose carbohydrate products. These carbohydrate products are then variously used to form other organic compounds, such as the building material cellulose, as precursors for lipid and amino acid biosynthesis or as a fuel in cellular respiration. The latter not only occurs in plants, but also in animals when the energy from plants get passed through a food chain. Organisms dependent on photosynthetic and chemosynthetic organisms are called heterotrophs. In general outline, cellular respiration is the opposite of photosynthesis: glucose and other compounds are oxidised to produce carbon dioxide, water, and chemical energy. However, both processes actually take place through a different sequence of reactions and in different cellular compartments.

Plants capture light primarily using the pigment chlorophyll, which is the reason that most plants have a green color. The function of chlorophyll is often supported by other accessory pigments such as carotenes and xanthophylls. Both chlorophyll and accessory pigments are contained in organelles (compartments within the cell) called chloroplasts. Although all cells in the green parts of a plant have chloroplasts, most of the energy is captured in the leaves. The cells in the interior tissues of a leaf, called the mesophyll, contain about half a million chloroplasts for every square millimeter of leaf. The surface of the leaf is uniformly coated with a water-resistant, waxy cuticle, that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or blue light to reduce heating. The transparent epidermis layer allows light to pass through to the palisade mesophyll cells where most of the photosynthesis takes place.

Answer 8

The Chloroplast. Its not Ribosomes. This is where proteins are made. The gas exchange then is released by the stomata (part of the choloroplast)

Answer 9

It takes place at the chloroplast which contains chlorophyll to make food

Answer 10

The spongy and palisade messophyll and in the guard cells of the stomata.
