Cell Diversity (Plants)

Tissue

Is a group of similar cells that are carrying out the same function

4 types of plant tissue

1. Dermal tissue

2. Vascular tissue

3. Ground tissue

4. Meristematic tissue

Dermal tissue

A single layer of cells that covers different parts of a plant. The epidermis, it protects the plant.

Ground tissue

Fills the inside of the plant and gives support to the plant and also stores food (starch). Photosynthesis occurs here.

Vascular tissue

Transports minerals around the plant. There 2 types of vascular tissue, xylem and phloem.

Xylem

Transports water and minerals around the plant from root to leaf (passive movement - no energy) and support plant because of lignin. They are dead, hollow cell stacked.

2 types of xylem

Vessels and tracheids

Phloem

Transports food (sugar/glucose) from the leaves to other parts of the plant (active transport). Living cells stacked have cytoplasm but no other organelles. Energy is provided by companion cells.

Meristematic tissue

Is for growth, its the area where cell division takes place (mitosis). Tip of roots and shoots.
