Cells must contain chloroplasts, which are organelles that contain chlorophyll, in order to perform photosynthesis.
Well what is the point of chloroplasts? They help with photosynthesis and other chemical reactions like that. What uses photosynthesis? Not animals. They get their energy from food. Plants use photosynthesis to get energy from the sun. So what's your answer? Just pants!
In order for photosynthesis to occur, the organelle chloroplast is needed. Eukaryotic cells (typically plants) do contain chloroplasts which the plant can use to make food. However, there are several prokaryotic organisms such as the purple bacteria that contains a different kind of chlorophyll and can photosynthesize.
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont needchloroplasts, so they dont have them.
Organisms that cannot perform photosynthesis rely on obtaining energy by consuming other organisms or organic matter. They can break down these sources of energy through processes like cellular respiration to generate ATP, which is used as energy currency in cells. This allows them to power their cellular activities and functions.
Organisms that have photosynthetic pigments most always photosynthesize. Plants, many types algea and protists are capable of photosynthesis. Cyanobacteria, prokaryotic organisms, are also capable of photosynthesis. All these organisms contain chlorophyl a, but they all have a different set of pigments. There are different classes of these pigments: chlorophyll, cartenoids, and phycobilins. For a more detailed description of these pigments, see the link below.
Plants carry out photosynthesis - which occurs in the chloroplast. Animals cannot photosynthesize.Plant cells have evolved a way to use light to provide energy for photosynthesis. The chloroplasts contain the pigment chlorphyll which allows them to utilize the energy from light. Animal cells evolved without the cellular machinery to perform photosynthesis, therefore they do not have chloroplasts and are heterotrophs, needing to feed on another organism in order to survive.
Most, but not all plant cells contain chlorophyll. Chlorophyll requires light in order for photosynthesis to occur, it make no sense then that plants produce chlorophyll in cells where no sunlight can reach; for this reason root cells and tissues do not contain chlorophyll
Plants need carbon dioxide in order to perform photosynthesis....they also do need to do this in an aerobic environment (in air, which does contain oxygen).
Some protists are producers. They contain special structures called chloroplasts that capture solar energy in order to perform the process of photosynthesis.

Photosynthesis.
Palisade parenchyma cells are specialized for photosynthesis in plant leaves. They are packed with chloroplasts that contain chlorophyll, which is essential for capturing light energy to convert into chemical energy through photosynthesis. The tall, cylindrical shape of palisade cells allows them to be densely packed together, maximizing their exposure to light in order to efficiently carry out photosynthesis.
