Study Notes
Organisms and Their Life Cycles
- Living things, such as bees and plants, are known as organisms.
- Organisms change as they get older, but different organisms change in different ways.
Life Cycle Stages
- Life cycles follow a pattern that happens in a certain order:
- Birth
- Growth
- Reproduction
- Death
Reproduction and Offspring
- Reproduction means producing new animals or plants like themselves.
- When organisms reproduce, the young are called offspring.
- Traits are features that are passed down from parents to their offspring.
- Each parent gives some of its traits to its offspring.
Inherited Traits
- Characteristics passed from parents to their offspring are inherited traits.
- Examples of inherited traits include:
- Eye color
- Shape of a plant's leaves
- Presence of spines in a cactus
Types of Organisms and Their Traits
- Hawks have large, sharp beaks and strong wings to hunt and catch prey.
- Sparrows have small beaks and narrow wings to eat insects and seeds.
- Cardinals have small beaks because they eat seeds.
- Falcons do not eat berries and seeds.
Plants and Their Life Cycles
- Flowering plants come in many varieties, but they all follow a similar life cycle.
- Germination of a seed is the first stage, when a root begins to sprout from the seed.
Reptiles and Their Habitats
- Examples of reptiles that spend time living partly on land and partly in water include salamanders.
