What do photosynthetic mean?
photosynthesis. / (ˌfəʊtəʊˈsɪnθɪsɪs) / noun. (in plants) the synthesis of organic compounds from carbon dioxide and water (with the release of oxygen) using light energy absorbed by chlorophyll. the corresponding process in certain bacteria.
What is the definition of chloroplast in biology?
A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.
What does chlorophyll mean in biology?
photosynthesis
Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis. Biology, Ecology.
What is respiration in biology?
Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).
What is the definition of photosynthesis equation?
The photosynthesis equation in words is: Carbon Dioxide + Water + Sunlight ———> Glucose (simple sugar) + Oxygen. Here’s a breakdown of that equation. The reactants of photosynthesis are everything to the left of the “———>” arrow, thus the reactants of photosynthesis are carbon dioxide, water, and sunlight energy.
Where are most photosynthetic cells in plants found?
chloroplasts
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. Color and label the outer membrane (1) green.
What is the best definition of chloroplast?
: a plastid that contains chlorophyll and is the site of photosynthesis — see cell illustration.
What is chloroplast give example?
The definition of a chloroplast is a part of a plant that has chlorophyll and conducts photosynthesis. An example of a chloroplast is a cell in algae that consumes carbon dioxide and releases oxygen while creating sugar.
What is chlorophyll short answer Class 4?
Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. Chlorophyll absorbs energy from sunlight, and this energy is later used to convert carbon dioxide into carbohydrates.
What is chlorophyll class 7th answer?
Chlorophyll is a green pigment found in the leaves and green stems of plants.green pigment trap light energy from the sun, which is then used to combine carbon dioxide and water into sugar in the Process of photosynthesis.
What is respiration short answer?
1 : the act or process of breathing : the inhaling of oxygen and the exhaling of carbon dioxide. 2 : the process by which cells use oxygen to break down sugar and obtain energy.
What is respiration in animals?
Respiration is the exchange of life-sustaining gases, such as oxygen, between an animal and its environment. Gas exchange occurs by diffusion, moving necessary gases like oxygen into animals and taking away waste gases like carbon dioxide.
What are the three things needed for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
What is the literal meaning of photosynthesis?
Photosynthesis literally means synthesis (or manufacturing) with light. It is the physiological process occuring in plants by which carbon dioxide (CO 2) and water (H 2O), in the presence of visible light and chlorophyll, are converted to organic compounds which store chemical energy.
What are the basics of photosynthesis?
Photosynthesis is a complex series of reactions. At the simplest look, photosynthesis consists of carbon dioxide (CO₂) and water (H₂O) being converted into glucose (C₆H₁₂O₆) and oxygen (O₂) with help from the sun’s energy.
What are the steps in photosynthesis?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma,…
