Structures of plants and animals

Plants consist of root and shoot systems.

$$\begin{cases} \text{Root system:} & \text{roots (absorb water and nutrients)} \\ \text{Shoot system:} & \text{stem, leaves, flowers, fruits} \end{cases}$$

Animals have organ systems.

$$\begin{align*} &\text{Integumentary (skin)}, \\ &\text{Digestive (mouth to anus)}, \\ &\text{Circulatory (heart, vessels)}, \\ &\text{Respiratory (lungs or gills)}, \\ &\text{Nervous (brain, nerves)}, \\ &\text{Reproductive} \end{align*}$$

Both have:

1. Cells

2. Tissues

3. Organs

4. Organ systems

Final answer: Plants and animals share cellular organization but differ in specific structures (plants: vascular; animals: organ systems).

Plants: roots, stems, leaves, flowers, fruits. Animals: skin, digestive system, circulatory system, respiratory system, nervous system.
