Photosynthesis – Photosynthesis is the process plants use to convert sunlight into chemical energy. Light is absorbed by tiny organelles in the leaves of the plant, where it is processed via a series of chemical reactions and then stored in the plant. When consumed by herbivores, or plant-eating organisms, the energy stored in the plant is transferred to the consumer. Photosynthesis Photosynthesis is a two-part process. Each part is made up of several chemical reactions — some that occur in daylight, called light reactions, and others that occur in the absence of light, called dark reactions. Carbon dioxide, water, light and minerals are processed through the various reactions to produce carbohydrates and oxygen. Carbohydrates are the energy-containing molecules that humans and animals ingest to power their own metabolic pathways. Oxygen, a waste product to plants, is necessary for respiration in mammals. Chlorophyll Chlorophyll is the pigment in plants and some bacteria that powers the reactions of photosynthesis.
BIOdotEDU – However the most easily recognizable plastid is the chloroplast, a green organelle that harvests light, then uses the trapped energy to synthesize sugar molecules, which are then stored as starch.
Video advice: Photosynthesis – 3rd Part
This is the Third Part of Photosynthesis. A series of videos are present in this playlist for complete understanding of the video with proper explanation in animated form . This video gives explanation about every component or organelles involved in Photosynthesis. Also the source of this components from which they involved.
Sunlight striking a chloroplast is absorbed and the energy the sunlight contains is converted to electron energy in the grana membranes. This electron energy is eventually converted to chemical energy by molecules and enzymes in the stroma matrix of the chloroplast. The final product is usually the sugar glucose which is then polymerized into starch.
: Cell Structure: Chloroplasts
Biology4Kids.com! This tutorial introduces plant chloroplasts. Other sections include plants, animal systems, vertebrates, and microorganisms.
The objective of the chloroplast would be to make sugars that feed the cell’s machinery. Photosynthesis is the procedure of the plant taking the sun’s energy and creating sugars. Once the the sun’s energy hits a chloroplast and also the chlorophyll molecules, light energy is changed into caffeine energy present in compounds for example ATP and NADPH.

There are other molecules that are also photosynthetic. One day you might hear about carotenoids in carrots, phycocyanin in bacteria, phycoerythrin in algae, or fucoxanthin in brown algae. While these compounds might be involved in photosynthesis, they are not all green or the same structure as chlorophyll. Accessory pigments such as carotenoids and fucoxanthin pass absorbed light energy to neighboring chlorophyll molecules instead of using it themselves.

What are the organelles involved in photosynthesis and cellular respiration?
Chloroplasts and mitochondria are the organelles involved in photosynthesis and cell respiration respectively.
How can prokaryotes perform cellular respiration without membrane-bound organelles? To live, prokaryotes for example bacteria have to produce energy from food for example glucose. In eukaryotic cells, respiration is conducted by mitochondria, but prokaryotic cells don’t have membrane-enclosed organelles.

- Abstract
- A “malate valve” controls the export of reducing equivalents from the chloroplasts
The chloroplast (plastid) genomes (plastomes) are much smaller than the nuclear genome – typically from 130 to 170kb long depending on the species – and carry 100 to 200 genes including many critical to the photosynthesis that occurs in the chloroplast. From: Encyclopedia of Applied Plant Sciences (Second Edition), 2017ChloroplastsRandy Wayne, in Plant Cell Biology, 2009Publisher SummaryChloroplasts are organelles specializing in the conversion of radiant energy to chemical energy. The chloroplast is involved in photosynthesis and consequently cells that contain chloroplasts are autotrophic, which means that they are able to make their own food from inorganic molecules by using the radiant energy of sunlight. The chloroplast converts the radiant energy of the sun into chemical energy by producing organic matter from carbon dioxide and water. The individual reactions of photosynthesis span times from femtoseconds to hours and can be divided into two major groups, reactions that require light directly and reactions that do not require light directly.

Molecular Expressions Cell Biology: Plant Cell Structure
The most important characteristic of plants is their ability to photosynthesize, in effect, make their own food by converting light energy into chemical energy. This process is carried out in specialized organelles called chloroplasts.
Probably the most broadly recognized and important characteristics of plants is the capability to conduct photosynthesis, essentially, to create their very own food by converting light energy into chemical energy. This method happens in just about all plant species and it is transported in specialized organelles referred to as chloroplasts. All the eco-friendly structures in plants, including stems and unripened fruit, contain chloroplasts, but nearly all photosynthesis activity in many plants happens in the leaves. Around the average, the chloroplast density at first glance of the leaf is all about one-half million per square millimeter.
