Photosynthesis happens inside the chloroplasts, which are found in leaf cells and in other green parts of
a plant. Chloroplasts contain a substance called chlorophyll, which absorbs sunlight and uses…

How Plants Use the Glucose
1. For Respiration
Plants manufacture glucose in their leaves.
They then use some of the glucose for respiration.
This releases energy which enables them to convert the rest of the glucose into various other useful
substances which they can use to build new cells and…

Nutrients and Minerals Needed for Healthy Growth
Plants need the carbohydrates they get from photosynthesis and various mineral salts to grow properly.
They get the mineral ions by absorbing them from the soil through their roots ­ active transport:

Nitrates
These are needed for making amino acids, which are then…
