What is photosynthesis and where does it take place in a plant?

In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.

How does photosynthesis happen in plants?

Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll. We, in turn, exhale the carbon dioxide needed by plants.

What is photosynthesis and where does it occur quizlet?

Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct, occurs in plants and some bacteria. Photosynthesis takes place inside plant cells in small things called chloroplasts.

Where does photosynthesis start?

Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.

In which part of the chloroplast does photosynthesis occur?

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).

Where oxygen comes from in photosynthesis?

The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.

Where in a plant does photosynthesis happen quizlet?

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.

What are the 3 major steps of photosynthesis?

The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves.

Water gets into the plant mainly through the roots and finds its way to the leaves,where photosynthesis occurs.

Chlorophyll,the green coloring matter of the leaf,traps the energy from sunlight as it shines on the leaf.

What do plant cells need for photosynthesis?

Photosynthesis is the process by which new lease of energy is made available to the plant. For photosynthesis, plants need light, water, carbon dioxide and chlorophyll. The chlorophyll converts water from soil and carbon dioxide from air into oxygen and sugar in the presence of sunlight.

Why is photosynthesis important for all organisms?

Photosynthesis is important for all living organisms because it provides the oxygen needed by most living creatures for survival on the planet.

What organelle is involved in photosynthesis?

Chloroplasts are organelles in plant and bacteria cells that contain the chlorophyll used in photosynthesis. They are bound by a double membrane that contains many folds; this double membrane encloses many other membranous structures, called thylakoids .
