Homework Answers
1. Independence from water to carry out sexual reproduction, fertilization.- Pollen allows angiosperms to reproduce away from water, unlike mosses and ferns which require water for sperm to swim to the female gametophyte.
Use animals to increase the chances of sexual reproduction.- animals help in the dispersal of fruits and seeds and pollen grains thus increasing the chances of sexual reproduction.
Use animals to increase dispersal.-animals and human beings help in fruit, seed and pollen dispersal.
2. Animals can be recruited to help transport pollen. - bees, insect and animals help in the pollen dispersal
Increased efficiency of pollen.- pollens are efficient for sexual reproduction.
The embryo will develop faster- embryo is protected in the seed in angiosperms.

3) You plant a seed in a pot with soil, add water, and then place it in the sunlight in a closed chamber. Before the seedling emerges from the soil, carbon dioxide levels increase in the closed chamber. This indicates that is occurring. A) cellular respiration B) alcohol fermentation C) sucrose production D) fertilization E) photosynthesis directs water from the roots into the 4) The waxy barrier called the endodermis and then into the xylem.

1. A student uses iodine to visualize cells under the light microscope. Iodine stains starch deep blue and glycogen granules dark brown. Observation of the cells reveals the presence of cell walls, dark brown granules, mitochondria, and a prominent nucleus. If the chemical composition of the cell wall is determined, which of the following molecules would MOST likely be the major constituent? A. cellulose B. chitin C. lignin D. peptidoglycan 2. Which of the following statements is the MOST compelling...

1. In this question, assume that the life cycle of a flowering plant begins with the germination of a seed and ends with the development of a fruit. Two events that occur in the life cycle are formation of a pollen tube and pollination. What would be the sequence in which they occur? Group of answer choices Both events occur more or less simultaneously. Formation of a pollen tube precedes pollination. pollination precedes the formation of a pollen tube 2....

1. The flower of an angiosperm that relies on wind to disperse pollen will be: a) colorful. b) odiferous. c) large. d) small. 2. Why might asexual reproduction typically result in local colonization, while the products of sexual reproduction are typically dispersed? Select all that apply. a- Vegetative propagation is more efficient than sexual reproduction when the current generation is well-adapted to the local environment. b - The variation resulting from meiosis and the union of gametes means some individuals...

1. In ferns, some leaves are “fertile” in that they bear sporangia. What are the structures in gymnosperms that are analogous to a leaf and sporangia? Select all that apply. cone scales and ovules seed coat and embryo cone scale and pollen-producing sporangia cones and seeds 2. You are on an expedition in a tropical rainforest. You notice a tall plant with large, long, conical purple flowers that produce nectar. When you ask your guide about the plant, she pulls...

1) What were some of the challenges that plants had as they moved onto land? (Check all that apply.) A. They no longer had structural support of water. B. They didn’t have water to stop dispersal of gametes. C. They were in danger of drying out without water. D. They were not as susceptible to predators and predators. 2) Pollen grains were a great adaptation for land plants because A. They allowed for dispersal for gametes via wind or animals...
