The process of photosynthesis occur in plant cells mainly because of the presence of special cells known as chloroplasts. These chloroplasts contain a green pigment known as CHLOROPHYLL. This pigment makes use of energy from sunlight to split water molecules into their constituent hydrogen and hydroxide ions,(a process known as PHOTOLYSIS OF WATER). The hydrogen ions thus react with the carbon dioxide within the cells to form carbohydrates.
On the contrary, animal cells lacks this chloroplasts, hence the absence of CHLOROPHYLL. Since there is no chlorophyll, there is on mechanism for the photolysis of water that will lead to the formation of carbohydrates, thus photosynthesis does not occur in animal cells.

∙ 12y agoIt does not occur in the cell wall and membrane, mitochondria, vacuoles, nucleus, Golgi complex, endoplasmic reticulum, ribosomes, lysosomes and nuclear membrane. It occurs in the chloroplasts.

∙ 13y agoBecause the green in a plant is from the chlorophyll inside the chloroplasts in the plant cell. The chlorophyll is also responsible for photosynthesis, and without the chlorophyll (green colour) there can be no photosynethesis

∙ 12y agoAnimal Cells dont need chloroplasts or chlorohpyll. Plants need them in order to inhance the nutrients taken in by the C02 in the air. Chloroplasts are green because they contain the pigment chlorophyll.Which in theory makes plants green.

What thing have to happen for photosynthesis to occur?
What is needed to occur is Water, Carbon Dioxide, chorophyll, sunlight for the Photosynthesis to occur.
Why does photosynthesis occur in leaves?
Photosynthesis needs sunlight to occur. Therefore photosynthesis does not occur in the roots because they do not receive any sunlight. The leaves are the parts of the plant most exposed to the light.
What is photosynthesis in what major organelle does it occur in?
Photosynthesis is the process of making food in the presence of sunlight. It occur in chlorophyll.
What part of a whale does photosynthesis?
Whales are mammals, animals, and photosynthesis is not a property or activity of animals.
What does not occur in photosynthesis?
Release of oxygen does not occur.
What would happen to photosynthesis in a plant grown that doesnt have water?
Photosynthesis in plants cannot occur without water.
What happens if vegetables don't get enough sun?
they die obviously....becoz photosynthesis doesnt occur.
Do photosynthesis occur in plants and animals?
Photosynthesis only occurs in plants, on the leaves, to produce nutrients for it. Animals all respire, which is effectively the opposite of respiration.
What is one reason that photosynthesis does not occur in animals?
Photosynthesis does not occur in animals because we can not (nor do we need to) make our own food through a chemical process involving sunlight, oxygen, and water that turns those three ingredients into sugar.
What organelle has to be present for photosynthesis to occur?
chloroplasts, because photsynthesis only occurs in plants, not animals
What thing have to happen for photosynthesis to occur?
What is needed to occur is Water, Carbon Dioxide, chorophyll, sunlight for the Photosynthesis to occur.
Where does The reactions of photosynthesis occur in the of plant cells.?
The reactions of photosynthesis occur in the chloroplast in the cells in plants.
How do animals depends on photosynthesis?
Animals depend on photosynthesis for food and oxygen.
Why does photosynthesis occur in leaves?
Photosynthesis needs sunlight to occur. Therefore photosynthesis does not occur in the roots because they do not receive any sunlight. The leaves are the parts of the plant most exposed to the light.
What is photosynthesis in what major organelle does it occur in?
Photosynthesis is the process of making food in the presence of sunlight. It occur in chlorophyll.
Does photosynthesis occur in the chloroplasts?
Yes - photosynthesis occurs in the chloroplasts.
Where does the photosynthesis occur?
Photosynthesis occurs in the chloroplasts of a plant cell.
