How do plants reproduce asexually?

Lesson Review

Write true if the statement is true. If the statement is false, change the underlined term to

make the statement true. ____________________ 1. Reproduction without the joining of male and female sex cells is sexual

reproduction.

____________________ 2. An onion is an example of a tuber.

____________________ 3. One type of sexual reproduction in plants is called vegetative propagation.

____________________ 4. Vegetative propagation uses seeds of plants to grow new plants.

____________________ 5. New plants that grow from vegetative propagation are different from the parent

plant.

Seed dispersal Enrichment Activity

Skills: inferring, applying concepts, predicting

New plants form from seeds released by parent plants. Survival of a plant species is dependent upon the dispersal of

parent plant seeds. Many plant seeds have characteristics that help in their dispersal. Wind, water, and animals all

help seeds to be dispersed.

PART A Look at the plant seeds below. Identify the trait of the plant seed that helps in

its dispersal. Predict how the seed is dispersed.

PART B Read the following passage. Then, answer the questions that follow.

Tomato Plant

Red, juicy tomatoes are the fruit of the tomato plant. It is believed that tomatoes grew naturally

in South America. Spanish priests visiting South America probably brought the seeds of these

plants back with them to Europe. During the 1500s, tomatoes were grown as food in Spain and

Italy. Years later, European explorers brought the seeds of these plants with them on voyages to

America. Today, the United States produces more tomatoes than any other country.

1. How did humans aid the dispersal of tomato seeds? ____________________________________________

2. Suppose that Spanish priests had never taken tomato seeds back to Europe. What effect could this have had on

U.S. farms today?

Fertilizers are graded. The first number is the percentage of nitrogen (N), the second

number is the percentage of phosphoric acid (PA), and the third number is the

percentage of potash (P). Use the information below each picture about the

percentage of nutrients in fertilizers to make a pictograph (represent each using their

symbols) in the spaces on the bags provided.
