Photosynthesis
This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

What do plants have that allows them to collect sunlight and do photosynthesis?
Plants contain organelles, or tiny things in their cells that do work, called chloroplasts. These chloroplasts contain thylakoids, which convert light energy into chemical energy.

What does photosynthesis make?
Photosynthesis produces glucose (sugar) and oxygen using carbon dioxide, water, and sunlight. These products are essential for the plant's growth and survival.
What is the main pigment used in photosynthesis?
Photosynthesis is when a plant (or other type of cell) uses sunlight to make energy. The chloroplasts are the organelles that capture sunlight, and is also the thing that makes a leaf green. This happens because of the pigment of chlorophyll. (I'm in 8th grade btw) :)
Photosynthesis occur in chloroplast?
Yes, photosynthesis occurs in the chloroplasts of plant cells. Chloroplasts contain chlorophyll, the pigment responsible for capturing light energy, which is used to convert carbon dioxide and water into glucose and oxygen in the presence of sunlight.
Which structures does the Calvin cycle take place?
the light independent reactions occur in the thylakiod, another name you could say grana. and the Calvin cycle occurs in the stroma. and they both of coarse occur in the chloroplast of the plant cell.
Can photosynthesis occur under water?
Yes! Because water is used to make glucose (by photosynthesis) a shortage of water could and would directly affect the process of photosynthesis. When there is no water, the guard cells close the stomata in order to conserve water, this action shuts of the plants supply of carbon dioxide, slowing the rate of photosynthesis, and if not given water the plant will run out of simple sugars and starch and die.
What gas needed for photosynthesis enters through stomata of the cactus stem?
Carbon dioxide is the gas needed for photosynthesis that enters through the stomata of the cactus stem.
In what part of a plant cell does photosynthesis occur?
in which part of a plant cell does photosynthesis occur
Why is carbon dioxide important to photosynthesis?
It is an important part of the chemical process, providing the carbon needed to build carbohydrates. The overall chemical equation of photosynthesis is: 6CO2 + 6H2O --> C6H12O6 + 6O2. The carbohydrates are used as "food" by the plant and to form the cellulose that make up the stem and leaves.
What is an organism that makes food by photosynthesis?
A plant is an organism that makes food by photosynthesis. This process involves using sunlight to convert carbon dioxide and water into glucose, a type of sugar that serves as the plant's food source.
Where photosynthesis takes place?
Photosynthesis takes place in the chloroplasts of plant cells. Specifically, the light-dependent reactions occur in the thylakoid membranes, while the light-independent reactions (Calvin cycle) occur in the stroma of the chloroplast.
Where does photosynthesis generally occur?
Photosynthesis generally occurs in the chloroplasts of plant cells. Within the chloroplasts, pigments like chlorophyll capture sunlight and convert it into chemical energy, which is used to produce glucose from carbon dioxide and water. This process is essential for the survival of plants and other autotrophic organisms.
The series of reactions during photosynthesis that create complex carbohydrates is called the Calvin cycle. This process occurs in the stroma of chloroplasts and involves the conversion of carbon dioxide into glucose using ATP and NADPH generated during the light-dependent reactions.
The ultimate original source of energy for all living things on Earth is the sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert solar energy into chemical energy, which is then passed on to other organisms through the food chain. This energy is used by organisms in cellular respiration to carry out essential life processes.
Does mitochondria energy occur in respiration?
mitochondria creates energy from the raw energy made sunlight(photosynthesis) and food(cellular respiration) which converts it into atp(adenosine triphospate) which can be used as the energy currency.
Is carbon dioxide a waste product of photosynthesis?
An example is carbon dioxide being emitted from car exhausts. Hope that helped.
What are pores surrounded by guard cells in the epidermis of a leaf?
Pores, known as stomata, are surrounded by two specialized cells called guard cells in the epidermis of a leaf. These guard cells control the opening and closing of the stomata, regulating the entry of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They help to maintain the balance of gas exchange and water regulation in the leaf.
The product of photosynthesis is glucose, a simple sugar that serves as a source of energy for plants and other organisms. This process also produces oxygen as a byproduct, which is released into the atmosphere.
What is the compound needed for photosynthesis?
CO2 and H2O are two essential basic compounds for photosynthesis which occur in presence of sunlight
The process by which certain organisms capture energy from sunlight and use it to build energy-rich food molecules is called photosynthesis. During photosynthesis, light energy is absorbed by chlorophyll in the chloroplasts of plant cells, and this energy is used to convert carbon dioxide and water into glucose and oxygen.
Part of the plant where photosynthesis occurs?
Photosynthesis occurs in the chloroplasts of plant cells. These organelles contain chlorophyll, which captures sunlight and converts it into energy that the plant can use to produce glucose. The chloroplasts are typically found in the cells of plant leaves.
What major2and accessory4pigments are necessary for photosynthesis to be carried out?
The two major pigments necessary for photosynthesis are chlorophyll a and chlorophyll b. A key accessory pigment is carotenoids, which help to broaden the range of light wavelengths that can be used for photosynthesis.
This question highlights some of the many problems when Genesis is not understood as the writer clearly intended it to be understood. The Hebrew word for day, yom, can mean an indefinite period of time (this could possibly include the 1000 year idea). When coupled with 'evening and morning' as it is in Genesis 1 it can only mean a 24-hour day as we know it today.
The idea of a 1000 years comes primarily from the verses below. It must be recognized that this is a metaphor and not literal. Note the word 'as' in 2 Peter. Moses in Psalm 90 is demonstrating the greatness of God in referring to His timelessness and sovereignty over even time itself. Neither of these have any bearing on the days of Genesis 1 which is primarily a historical narrative of the creation event.
8But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. 4For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night. Further to this it must also be noted that light was created on day 1 as per the verses below.
3And God said, Let there be light: and there was light. 4And God saw the light, that it was good: and God divided the light from the darkness. 5And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
12And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good. 13And the evening and the morning were the third day.
The plants were created on day three, in the presence of light which already existed from day 1. Even if it argued hypothetically that it didn't, there is only one day of 24 hours between day 3 and 4 when the sun etc was created.
