PHOTOSYNTHESIS

Photosynthesis: the jamming together of CO₂ (carbon dioxide) with H₂O (water) to make CH₂O (sugar) and O₂ (oxygen), using the sun's energy. The sugar contains the stored energy and serves as the raw material from which other compounds are made

Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy

PLANT TISSUES

They are the tissues that are responsible for the chemical reactions and metabolisms undertaken by a plant. They are divided into different groups depending their function and origin. Plant tissues are broadly categorized into three 1. Epidermis 2. Vascular 3. Ground tissues.

Epidermis - Cells forming the outer surface of the leaves and of the young plant body.

Vascular tissue - The primary components of vascular tissue are the xylem and phloem. These transport fluid and nutrients internally.

Ground tissue - Ground tissue is less differentiated than other tissues. Ground tissue manufactures nutrients by photosynthesis and stores reserve nutrients.

Plant tissues are further divided into 1. Meristematic tissues and 2. Permanent tissues.
