Photosynthesis | Definition of Photosynthesis by …

The  are the organelles where the two stages of photosynthesis take place.

Photosynthesis - The cycle of plants and how they make energy

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Here is a more complete definition of transcription:

Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes. In the cell cytoplasm, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein. Here is a more complete definition of translation:

What Kind of Reaction Is Photosynthesis? | Sciencing

The granum (plural grana) is a stack of which contains the photosynthetic pigments; this is where the light dependent stage takes place:

The DNA Learning Center's (DNALC) website, the Howard Hughes Medical Institute's DNA interactive (DNAi) website, and the University of Utah's Genetic Science Learning Center website listed below contain excellent narrated animations describing transcription and translation. These animations are useful as a lecture supplement or for students to review on their own. The DNALC animations cover central dogma, transcription (basic and advanced), mRNA splicing, RNA splicing, triplet code and translation (basic and advanced). The DNAi modules," Reading the Code" and "Copying the Code," describe the history of the process, the scientists involved in the discovery, and the basics of the process, and also include an animation and interactive game. Particularly useful to students are the interactive animations from the University of Utah that allow one to, for example,"Transcribe/Translate a Gene"or examine the effects of gene mutation as they "Test Neurofibromin Activity in a Cell."


Plants are the prime example of autotrophs, using photosynthesis

The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air.

Energy definition: The definition of energy explained.

In the ~2.5 billion years since photosynthetic organisms have appeared daily in this performance, enough oxygen has accumulated to account for 21% of the atmosphere...

That is actually how most lab reactions are done - in tubes or flasks (or whatever) open to the atmosphere, so that the pressure is constant at atmospheric pressure.The phrase "at constant pressure" is an essential part of the definition but, apart from that, you are unlikely to need to worry about it if you are doing a UK-based exam at the equivalent of A level.
