How Do Plant Life Cycles Vary?
Main Idea. Flowering plants produce seeds during their life cycles. The seeds grow into new flowering plants. Life spans vary for different types of plants.
Fill in the blanks with words from the box below.
11
embryo germinate life cycle
life span
1. A(n) _____________is a series of stages that occur during the lifetime of a living thing.2. A(n) _____________ is a plant or animal in the earliest stages of development. 3. Some plant seeds land in places where they can ___________ or begin growing a new
plant.4. A(n) _____________ is the length of time it takes an individual organismto complete its
life cycle.
Circle the word that completes the sentence.
5. The ( pistil or stamen) of a flower makes pollen, which is needed to form seeds. 6. Wind, water, and animals such as insects move (seeds or pollen) from the stamens to the
pistils. 7. Brightly colored (pistils or petals ) attract birds, bees and other insects to a flower8. In organisms that are similar, such as trees, the smaller kinds usually have (shorter or
longer) life spans than the larger kinds9. For flowering plants, the life span begins when a seed (germinates or sets pollen).
Study Guide B Ch 2
