What structures do plants need that animals not need?

Plants, unlike animals, need structures to perform photosynthesis, obtain water and nutrients from the soil, and provide support. Here are some key structures that plants have that animals don't:

For Photosynthesis:

* Chloroplasts: These organelles contain chlorophyll, the pigment that absorbs sunlight for photosynthesis.

* Leaves: Large surface area for capturing sunlight and exchanging gases.

* Stomata: Tiny pores on the surface of leaves that allow for gas exchange (carbon dioxide in, oxygen out).

For Obtaining Water and Nutrients:

* Roots: Absorb water and minerals from the soil.

* Root hairs: Tiny extensions on roots that increase surface area for absorption.

* Vascular tissues (xylem and phloem): These tissues transport water and nutrients throughout the plant.

For Support and Structure:

* Cell walls: Provide rigidity and support to plant cells.

* Woody tissues: In trees and shrubs, provide strong structural support.

* Stems: Provide support for leaves and flowers and transport substances.

Other Structures:

* Flowers: Specialized reproductive structures for attracting pollinators and producing seeds.

* Fruits: Enclose and protect seeds, sometimes aiding in seed dispersal.

It's important to note that some plants, like parasitic plants, may not have all these structures. However, these are the structures that are generally required for plants to thrive.
