Question

You are studying a beautiful little protist under a microscope. You can see that it has a particulary elaborate cel wall with an intricate. fancy pattern. The cell wall consists of a top and a bottom that fit neaty mo each cter Tests te al the cel wall court silica. Overal, your little protist appears yellowish brown.

Explanation / Answer

1. It must be Diatoms as they are the only organisms whose cell walls are made of silica and also, they have cell walls that are ornamented by intricate patterns of silica. So, Diatoms is the most appropriate answer.

2. The correct answer must be: A multicellular diploid organism produces haploid gametes.

In plants, a diploid plant cell divides by meiosis to form the gametes having half the number of chromosomes. These gametes then fuse to form a diploid organism. And the plant life fluctuates between the diploid and haploid stages. This mode of lifecycle is known as Alternation of Generation in which the organism fluctuatates between the diploid and haploid stages of life.

It is strictly not a process by which diploid organisms give rise to new haploid individuals or vice versa.

Option C. is a close answer but that stamement is incomplete with respect to Alternation of Generation and suits more to fertilisation process.
