Animals have many different features that they use to receive information about their surroundings. For example, a cat can use its whiskers to determine whether its body would fit through a tight space. Moths use their sense of hearing to avoid being hunted by bats. Birds of prey have long-distance sight to be able to spot prey from far away.

The passage describes how jellyfish are unique because they don’t have many of the features that most animals do have. However, they have tentacles that serve multiple purposes. They contain sensory nerves that allow jellyfish to see light, smell, and determine if an object is potential prey.

The plant has internal and external structures that aid in survival. The roots absorb water from the soil and keep the plant steady and stable, so it doesn't fall over. Without the roots, the plant would topple over and be dehydrated because of a lack of water.

The leaves on a plant are an external structure that assists in its survival. Without leaves, plants would not be able to make their food through the process of photosynthesis. The leaves absorb carbon dioxide and sunlight to turn into food for the plant. This structure is vital to a plant living and growing.

Flowers don't seem vital to a plant's survival, but they are an essential part of the process. They are the main structure for reproduction, so they aid in pollination to continue the development of new plants. Flower petals attract pollinators who then fertilize the plants, seeds are developed, and some plants produce fruits and vegetables, and pollinators are required for this process. Without the flower, all of these things would be impossible.

Erik is correct in his argument that plats have structures to keep them alive. Thorns, roots, leaves, flowers, and seeds are all examples of structures that plants have that keep them growing, reproducing, and living. Plants are living things that have adapted over the years to increase their rate of survival. If a plant has spines or spikes like thorns, something is less likely to eat it.

This statement is false. Plants have many structures that are suited for survival. Leaves, roots, flowers, petals, stems, and seeds are all examples of a structure that a plant has that keeps it alive. Each feature plays a specific part in the plant's survival. Plants have adapted to their surroundings to have the best opportunity at life.

Because fibrous roots can help hold a plant in the ground, in the event of flooding, this root system would help anchor the plant in place, thus allowing it to survive. While these types of roots do enable plants to absorb water, this ability alone would not cause the plant to survive an event such as a forest fire, lightning strike, or hurricane.

Leaves are an external structure of a plant. Leaves assist in the survival of the plant because they absorb carbon dioxide and sunlight to create food for the plant. This process is called photosynthesis, which the plant relies on to survive.

Flowers are the primary reproductive organs of the plants. The plant relies on the flowers to produce more of its kind so the species can survive.
