3.1a Each animal has different structures that serve different functions in growth,

survival, and reproduction.

•wings, egs ,or fins enable some animals to seek shelter and escape predators

•the mouth, including teeth, jaws, and tongue, enables some animals to eat and

drink

•eyes, nose, ears, tongue, and skin of some animals enable the animals to sense

their surroundings

•claws, shells, spines, feathers, fur, scales, and color of body covering enable

some animals to protect themselves from predators and other environmental

conditions, or enable them to obtain food

•some animals have parts that are used to produce sounds and smells to help the

animal meet its needs

•the characteristics of some animals change as seasonal conditions change (e.g.,

fur grows and is shed to help regulate body heat; body fat is a form of stored

energy and it changes as the seasons change)

3.1b Each plant has different structures that serve different functions in growth,

survival, and reproduction.

•roots help support the plant and take in water and nutrients

•leaves help plants utilize sunlight to make food for the plant

•stems, stalks, trunks, and other similar structures provide support for the plant

•some plants have flowers

•flowers are reproductive structures of plants that produce fruit which contains

seeds

•seeds contain stored food that aids in germination and the growth of young plants

3.1c In order to survive in their environment, plants and animals must be adapted to

that environment.

•seeds disperse by a plant ’s own mechanism and/or in a variety of ways that can

include wind, water, and animals

•leaf,flower, stem, and root adaptations may include variations in size, shape,

thickness, color, smell, and texture

•animal adaptations include coloration for warning or attraction, camouflage,
