Label the following structures on this photo:
1. Microsporangium
2. Microspores within the microsporangium
Homework Answers
Answer: The line that
denotes A represents the microsporangium and the line that points
to B represents the microspores.
The microsporangium is found in many plants such as seed plants( for example Pinus) in mosses and ferns. The microsporangium which is a sac-like structure contains microspores which represent the male sex cells produced by the process of meiosis from microspore mother cells. The opposite of the microsporangium and microspores in the megasporangium which contains the female sex cell i.e megaspore.

Which of the following statements is FALSE? Seeds include a source of nourishment of the developing embryo. A selective disadvantage of seeds is that the seed coat is highly vulnerable to invasion by fungi and bacteria. Most plants that produce seeds also produce nonflagellated sperm. Many seeds can remain dormant during long periods of drought or low temperatures. 5. In seed plants, fertilization can occur without the presence of water. 2 The world's tallest plants...

1. Submit a photo of your gel, showing the molecular weight markers and your lanes. Label the lanes, indicate the sizes of each marker protein, and put an arrow beside the sample protein bands that you measured. Give your figure a number (i.e., Figure 1) and an appropriate title. This title should go under your graph. (5 marks)
