Plant cells can have different structures and functions. Cells with similar structures and functions are combined to form tissues. 

Plants contain various kinds of tissues. They have specialized to fulfill different functions: for example, some tissues are specialized in photosynthesis and contain more chloroplasts than other kinds of tissue.

Plant tissues:

• The surface of the plant consist of superficial tissue.
• The upper surfaces of plant leaves contain photosynthetic tissue.
• The inside of the plant's stem and roots contain conducting or vascular tissue. The veins of plant leaves also consist of vascular tissue.

Green plants use specialized structures called stomates to regulate the intake and release of gases such as carbon dioxide and oxygen. These stomates are often located in the leaves of plants.

Plant leaves contain veins that transport water and nutrients to the photosynthetic tissue. When the leaves produce sugar, it is transported all the way to the roots via vascular tissue that runs through the plant's stem.
