Question

the following evaluation is intended to replicate the method of assessment and type of questions you will be asked on lab practicals. if you have difficulty with these questions, you may benefit from additional review of the specimens provided in lab.
1 identify the phylum (or supergroup) to which this organism belongs and identify the function of the structure indicated by line a.

2 identify the phylum (or supergroup) to which this organism belongs and identify its mode of nutrition acquisition.

Explanation:

Question 1

The first organism (likely Paramecium - shaped) belongs to Phylum Ciliophora (Supergroup SAR or Alveolata). Structure A (assuming it's a contractile vacuole) functions in osmoregulation (regulating water balance, expelling excess water).

The second organism (amoeba - like) belongs to Phylum Amoebozoa (Supergroup Amoebozoa). Its mode of nutrition acquisition is phagocytosis (engulfing food particles, like bacteria or organic debris, by forming pseudopodia to surround and ingest them, a type of heterotrophic holozoic nutrition).

Answer:

Phylum: Ciliophora (or Supergroup Alveolata/SAR); Function of Structure A: Osmoregulation (expels excess water to maintain internal water balance)
