Where in a cell does photosynthesis occur?
Photosynthesis occurs only in plant cells. This is because only plant cells (unlike animal cells) contain chloroplasts. These chloroplasts are the site of photosynthesis in the plant cell, and contain the necessary pigment of chlorophyll which is required for photosynthesis to take place. The photosynthesis equation is as follows: CO2 + H2O (in the presence of light and Chlorophyll) = energy + O2
What is Chloropast?
A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms.Read more: What_is_chloroplast
What part of the chlorophyll molecule absorbs light?
The magnesium atom at the center of the chlorophyll molecule is responsible for absorbing light. This magnesium atom interacts with the surrounding nitrogen atoms of the chlorophyll molecule to capture light energy during photosynthesis.
What organelle does photosythesis occur in?
Photosynthesis occurs in the chloroplasts of plant cells. These organelles contain chlorophyll, a pigment that captures light energy and converts it into chemical energy in the form of glucose.
In what part of a plant cell does photosynthesis occur?
in which part of a plant cell does photosynthesis occur
Why is chlorophyll a catalyst?
Chlorophyll is NOT really a catalyst. The presence of chlorophyll in the absence of light does not catalyze photosynthesis. Chlorophyll plays a part in photosynthesis, it captures light energy.

What is chlorophyll's importance in photosynthesis?
Chlorophyll helps to the plants absorb the light (reflects only the green light, all the other light it absorbs).
Which of the following photosynthetic reactions describe the reactions in which photolysis occurs?
Photolysis occurs in the light-dependent reactions of photosynthesis. These reactions include the light absorption by chlorophyll, splitting of water into oxygen and protons, and the generation of ATP and NADPH.

What are the special qualities of chlorophyll a?
Chlorophyll a can absorb solar energy, but only a few in the excited state of chlorophyll a can convert light energy into electricity.
Why is only the outer layer of a stem green?
Green comes from chlorophyll the photosensitive chemical in photosynthesis. It is only useful when there is light to exploit. There is no light inside the stem of the plant so there is no chlorophyll there.
Why is the primary pigment found in chlorophyll?
The primary pigment found in chlorophyll is chlorophyll itself, specifically chlorophyll a. It is responsible for capturing light energy during photosynthesis in plants. Chlorophyll absorbs mostly blue and red wavelengths of light, reflecting green light, making plants appear green.
What part of the chlorophyll molecule absorbs light?
The magnesium atom at the center of the chlorophyll molecule is responsible for absorbing light. This magnesium atom interacts with the surrounding nitrogen atoms of the chlorophyll molecule to capture light energy during photosynthesis.
Cellular repiration occurs only in the presence of?
Oxygen
Why is chlorophyll only found in plants?
Chlorophyll is found only in plants because it is a pigment essential for the process of photosynthesis, which is unique to plants. Photosynthesis is the process where plants convert light energy into chemical energy, using chlorophyll to capture sunlight. Animals do not carry out photosynthesis, so they do not require chlorophyll.
Is it true or false that only portions of visible light can be taken up by chlorophyll?
True, obviously the green part of the spectrum is not used which is why chlorophyll looks green when illuminated with white light.
