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.
This quiz covers the basics of living organisms, their changes, and life cycles, including birds and plants, suitable for Grade 3 students.
