Whats the process of photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What part of plant makes food?
leaves Green plants are the only organisms in the world that manufacture their own food. This process is called photosynthesis. It begins when sunlight (artificial light can power this too) strikes the plant's leaves. Inside the plant cell are parts called chloroplasts which contain a green pigment called chlorophyll.
Why do you think this process is called photosynthesis?
Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), "light", and sunthesis (σύνθεσις), "putting together".
What are the raw materials for photosynthesis?
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
How do plants make food?
Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.
What is respiration in plants?
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.
What is the name of plant food?
Solution: Leaves produce food for the plant. This process is called photosynthesis.
How do trees make food?
These cells actually make food through a process called photosynthesis. Chlorophyll cells take in carbon dioxide from the air. Chlorophyll cells combine this carbon dioxide with water sent up from the roots of the tree. In the chlorophyll cell, sunlight passes through this mixture and turns it into sugar and oxygen.
What type of reaction is photosynthesis?
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is found in chloroplasts in plant cells , particularly the palisade and spongy mesophyll cells .
How is respiration in plants and respiration in animals different?
In plants, the respiratory gases simply diffuse in and out of the cell by cell division whereas in animals there is gaseous transport of gases. The basic difference between plant and animal respiration is the procurement of glucose and oxygen.
How do plants obtain the carbon dioxide required for photosynthesis?
For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. The opening and closing of the pores of stomata is controlled by the guard cells only.
Which is a producer?
Producers are organisms that make their own food; they are also known as autotrophs. They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food. The most common example of a producer are plants.
How do plants make their food Class 4?
Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
How aerobic breakdown of pyruvate occurs in mitochondria?
Explanation. Pyruvate disintegrates into carbon dioxide and water in the mitochondria. This pyruvate conversion can be classified into three separate constituents of carbon dioxide along with water and energy, which occurs within the mitochondria cristae.
What is the site of aerobic and anaerobic respiration?
While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
What is food resource?
Food resources means all commodities and products, (simple, mixed, or compound), or complements to such commodities or products, that are capable of being ingested by either human beings or animals, irrespective of other uses to which such commodities or products may be put, at all stages of processing from the raw …
What are the sources of food Class 6?
Plants and animals are the main source of food for all the organisms on earth. Food obtained from animals is the main source of protein and include fish, milk, meat, poultry, and cheese. Whereas plants provide us with fruits and vegetables, which are an important source of fibres, proteins and carbohydrates.
What part of food makes?
Leaves Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar).
Which specific process in the light-dependent reactions produces oxygen and hydrogen ions?
So the source of hydrogen ions and oxygen, a gas in the light dependent reaction is the splitting of water or the photo analysis.
In what forms are oxygen and carbon dioxide transported in the blood?
Oxygen is carried both physically dissolved in the blood and chemically combined to hemoglobin. Carbon dioxide is carried physically dissolved in the blood, chemically combined to blood proteins as carbamino compounds, and as bicarbonate.
Why are gas exchange circulation and transport important to the survival of organisms?
Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.
How does photosynthesis transform solar energy into the chemical energy of sugar molecules?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Which of these is an adaptation of leaves for efficient gas exchange Brainly?
Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out….Features of leaves.
| Adaption | Purpose |
|---|---|
| Chlorophyll | Absorbs sunlight to transfer energy into chemicals |
What is consumer and producer?
When people make goods and services, goods and services, goods and services—when people make goods and services, they are producers. When they use the things produced, the things produced, the things produced—when they use the things produced, they are consumers.
What are called consumers?
Some animals eat these producers. These animals are called consumers because they consume something else to get their food. There are different types of consumers. An animal that eats producers, like plants or algae, is called an herbivore. Carnivores eat other consumers.
How do plants make their food Class 6?
Answer: Plants make their food through the process of photosynthesis. Because the synthesis of food occurs within them, they do not need to digest it. Therefore, they do not have a digestive system like humans.
How do plants make their food Class 7?
The process by which plants make their own food in the presence of sunlight, carbon-dioxide present in air, water, minerals and chlorophyll present in leaves is termed as photosynthesis.
Which molecule is metabolized in a cell to produce energy currency in the form of ATP quizlet?
Which molecule is metabolized in a cell to produce energy for performing work? Glucose is used to produce high-energy ATP in a cell.
What happens to the carbon molecules in the pyruvic acid that goes through the TCA cycle?
What happens to the carbon molecules in the pyruvic acid that goes through the TCA cycle? They become carbon dioxide.
Why do we get muscle cramps after vigorous exercise class 10?
This anaerobic breakdown of glucose leads to the formation of lactic acid in muscles. The accumulation of lactic acid in muscles leads to muscle cramps. Hence During heavy exercise, we get cramps in the legs due to the accumulation of Lactic acid. So, the correct answer is 'Lactic acid'.
