Meristematic Tissue Characteristics

Back

- Unspecialized tissue - Rapidly dividing (mitosis) - Found in roots and shoots - Responsible for new plant growth up/out (shoots) and down (roots)

meristematic tissue in plant growth regions

Front

Epidermal Tissue ("Dermal")

Back

Forms protective outer covering and allows for the exchange of materials and gases into and out of the plant.

Front

Ground Tissue

Back

Provides strength and support in the stem, stores food (sugars) and H₂O in roots, and is where photosynthesis occurs in leaves.

Front

Vascular Tissue

Back

Xylem transports H₂O up to leaves, and Phloem transports sugars from leaves.

Illustrates the location and function of different plant tissues.

Front

Photosynthesis process in plants

Back

Plants use CO₂ from the atmosphere to produce glucose and O₂, occurring in chloroplasts of leaf ground tissue cells.

Plants need to exchange gases (CO₂/O₂) with the environment.

Front

Function of stomata in plants

Back

Plants open and close stomata (singular stoma) underneath the surface of their leaves to exchange gases for photosynthesis.

Back

Illustration of guard cells and stomata, showing the process of opening and closing for gas exchange.

Front

Stomata function

Back

Stomata open and close due to the functioning of guard cells. Guard cells swell (open stomata) when H₂O moves inwards by osmosis and shrink (closed stomata) when H₂O moves outwards by osmosis.
