Summary Introduction

To write:

The forms of sexual and asexual reproduction occurring in the green algae.

Introduction:

Green algae belongs to the Phylum called the Chlorophyta consisting of the chloroplasts with chlorophyll a and b. They can be unicellular or multicellular inhabiting the freshwater, marine and terrestrial habitats. They reproduce both asexually and sexually.

Explanation of Solution

Vegetative reproduction in green algae occurs by fragmentation. In fragmentation, the body portions of the algae is separated giving rise to new individuals.

Asexual reproduction in Chlorophyta involves only one parent and occurs by the formation of zoospores or aplanospores. Zoospores are motile and aplanospores are non-motile. Both the spores on germination gives rise to new algae.

Sexual reproduction takes place through the formation and fusion of the two gametes. Sexual reproduction can isogamous, anisogamous or oogamous. In isogamy, the fusion of the gametes which are morphologically identical with similar size and structure takes place. Example: Spirogyra. Anisogamy is the fusion of two gametes of different size. Example: Chlamydomonas. In oogamy, fusion occurs between one large, non-motile female gamete with a smaller, motile male gamete. Example: Volvox.

The fusion is gametes results in the formation and the germination of the zygote by meiosis.

Conclusion

The asexual reproduction in green algae is by the formation of zoospores or the aplanospores and sexual reproduction occurs by the fusion of the gametes.

For each of the following problems calculate the following: (Week 6-3 Video with 6-1 and 6-2) Consult the total catabolic pathways on the last page as a reference for the following questions. A. How much NADH and FADH2 is produced and fed into the electron transport chain (If any)? B. How much ATP is made from oxidative phosphorylation (OP), if any? Feed the NADH and FADH2 into the electron transport chain: 3ATP/NADH, 2ATP/FADH2 C. How much ATP is made by substrate level phosphorylation (SLP)? D. How much total ATP is made? Add the SLP and OP together. 1. Aerobic respiration using 0.5 mole of glucose? NADH FADH2 OP ATP SLP ATP Total ATP Show your work using dimensional analysis here:
Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…
