Exercise 1

Step 1

1 of 2

Flowering plants are called **angiosperms**, they contain specialized structures such as flowers that will enable them to reproduce efficiently. There are found structures that make up the flower: Sepals, petals, stamens, and carpels. Hence, the correct answer is **D**

Exercise 2

Step 1

1 of 2

**Flowers** is the main reproductive organs of the **angiosperms**. Each flower has an anther (which serves as the male reproductive part) and a carpel (female reproductive part). Inside the flower, pollen grains are produced in the male reproductive part. Hence the correct answer is **C**

Exercise 3

Step 1

1 of 2

When a seed starts to mature, a fruit is formed. This occurs when the ovary walls get ripe and form a thicker wall that encloses the seeds. Therefore, the ovaries of flowers develop into fruits.

Exercise 4

Step 1

1 of 2

Flowers are the main reproductive organs of the angiosperms. Each flower has male and female reproductive parts. The female reproductive part of the flower is called the **carpel**. It is composed of the ovary, style, and sigma which houses the egg cells.Hence, the correct answer is **B**

Exercise 5

Step 1

1 of 2

Vegetative reproduction is a type of asexual propagation that uses the processes of cutting, grafting and budding. Flowers are mostly used for the sexual reproduction of angiosperms.

Exercise 6

Step 1

1 of 2

The endosperm found in a seed is a tissue that provides food and nourishment for a developing embryo. This tissue, which is a triploid cell, is produced from the fusion of sperm nucleus with two polar nuclei during the second stage of double fertilization. This process takes place inside the embryo sac.

Exercise 8

Step 1

The pollen is produced by the anther. This structure houses the male gametophytes or the pollen grains.

Exercise 9

Step 1

1 of 2

A fruit encloses the seeds of a certain plant. Tomatoes, corns, cucumbers, and pumpkins have their seeds enclosed in the ovary. Beets are nutritious root crops. Therefore, it is a tuber, and not a fruit.

Exercise 10

Solution 1

Solution 2

Step 1

1 of 2

The fruit that was carried farthest from parent tree was Norway maple as the average time for the seed to fall is 0.98. Hence, the options (a), (c), (d), and (e) are incorrect.

Hence, the correct answer is (b) Normal maple.

**Seeds** are usually moved or spread from the parent plant to another location through the process of seed dispersal. Seeds can be dispersed by different factors such as animals, wind, and water.

Step 2

2 of 3

In the given data, the fruit that has the highest average time for the seed to fall indicates that it was dispersed farthest from the parent plant. Hence, the correct answer is **B**, because the Norway maple has the highest value of time which is close to a minute before it landed to a certain location.

Exercise 11

Step 1

1 of 2

Wing-like structures in fruits create an advantage for seed dispersal. It allows them to be lightweight and it enables them glide to a farther distance due to the wings that make the fruit spin and twirl when blown by the wind.
