Give the name of the structure labeled H and state its function.

Here are the answers to the questions from the image: 1. (a) Give the name of the structure labeled H and state its function. H: Mitochondrion Function: It is the site of aerobic respiration, where glucose is broken down to release energy (ATP) for cellular activities. 1. (b) (i) In which cells between spermatozoa or ova would you expect to find a high number of the organelle named in (a) (i) above? Spermatozoa 1. (b) (ii) Give a reason for your answer in (b) (i) above. Spermatozoa require a large amount of energy for their motility (swimming) to reach and fertilize the ovum. Mitochondria produce this energy in the form of ATP. 2. (a) Name the gaseous exchange structure in the following organisms: i) Amoeba: Cell membrane ii) Grasshopper: Tracheal system 2. (b) The diagram below illustrates the structure of a gill from a bony fish. i) Name the parts labeled A, B, and C. A - Gill filaments B - Gill bar (or Gill arch) C - Gill rakers ii) State the function of the part labeled C. The functions of gill rakers are: 1. They filter food particles from the water, especially in filter-feeding fish. 2. They protect the delicate gill filaments from damage by large particles or debris in the water.
