How are plant and animal structures similar? How are they different?

Answer 1

Plant and animal structures are similar in that they are both composed of cells, tissues, and organs that work together to carry out various functions. Both plants and animals have specialized structures that are adapted for specific purposes, such as roots in plants for absorbing nutrients and support, and limbs in animals for movement.

However, there are several key differences between plant and animal structures. Plants have cell walls made of cellulose, while animals do not have cell walls. Plants have chloroplasts for photosynthesis, allowing them to make their own food, while animals rely on consuming other organisms for energy. Plants have roots, stems, and leaves for support, transport of water and nutrients, and photosynthesis, while animals have more complex organ systems, such as digestive, respiratory, circulatory, and nervous systems. Additionally, plants reproduce through seeds and spores, while animals reproduce through internal or external fertilization.
