The evolution of seeded angiosperms most closely followed the evolution of --- A. Insects , because many insects are pollinator.
As angiosperms evolved in Cretaceous period, many modern groups of insects are appeared. Mainly pollinating insects that drove the evolution of angiosperms are evolved.Pollinator spread pollen accidentally while feeding on flowers. In million of years pollinating insects and flowers have coevolved for mutual success. Insects feed on flowers and also the reproduction of flowers is continued. Two become mutually benefied.
Angiosperms produce flower structures on their sporophytes that hold male and female gametophytes. This evolutionary development...
Draw a basic flower and label die main parts from the following list: androecium or male floral parts (anther, filament, stamen), gynoecium or female floral parts (stigma, style, ovary, carpel), attracting a pollinator (petal), and provides support and/or protection (sepal).
Flower Dissection: Collow the steps in the procedure to identify the structures and their functions of a flower. Complete the following questions: 1. Select the Cherry Blossom to dissect. 2. Identify the correct function of each structure in the flower in the table below: Flower Structure Function Anther Filament Ovary Ovule Petals Sepals Stigma Style 3. What two parts make up the stamen (male reproductive parts)? 4. What four parts make up the pistil (female reproductive parts)? 5. Once you...
Plantae: 1. Which of the following correctly describes an evolutionary trend that occurred as land plants evolved? 2. Becoming seedless b. Producing one type of spole Producing nonmotile wametes d. Haploid generation becoming dominant 2. Which of the following occurs in the Ilie cycle of both masses and anglosperms? a. The sporophyte is the dominant generation b. The gametophyce is the dominant gcneration c Spores develop into sporophytes d. The sporophyte products sporcs 3. The evolution of which of the...
1. When you look at a pine or maple tree, the plant you see is a _____. 2. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, is a source of high-quality lumber, and is a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the...

The there the top of the same has two sacs, which produce - by meiosis. 3. Within an ovule, a megaspore mother sellepoes meliosis to produce four three of which die 4. A microspore underpoes mitosis and becomes a - the male gametophyte. 5....
