The study of these parts is a science centuries old. , known as the "Father of Plant Anatomy," published detailed microscopic drawings of these structures back in 1682. Later, Katherine Esau became one of the most famous plant anatomists of the 20th century, writing the definitive textbooks used by scientists worldwide.

Plant cells are not all identical. Just as your skin cells differ from your liver cells, plant cells differentiate into specific types with specialized functions. The study of these parts is a science centuries old
As the tree grows, the outer layers of bark (rhytidome) crack and slough off. The inner bark (functional phloem) is alive, but the wood (xylem) in the center may become non-conducting "heartwood," often colored with tannins and resins, while the outer "sapwood" still conducts water. : The bulk of the plant body, involved
At the core of every plant is a complex cellular structure. Unlike animal cells, plant cells possess a rigid made of cellulose for structural support, chloroplasts for photosynthesis, and a large central vacuole that maintains turgor pressure to keep the plant upright.
