Levels of Organization

• Cells➡Tissue➡Organs➡Organ Systems➡Organisms

• These levels of organization also exist in plants.

• Just like in animals, plants have different levels of organization. With lots of similar cells combining to form tissues. Different types of tissues combining to form organs and then multiple organs combing to form organ systems.

• Plant Cells➡Dermal, Vascular & Ground Tissue➡Leaf, Stem, Root➡Root System & Shoot System➡Plant
