Select the alternative giving correct identification and function of the organelle 'A' in the diagram.
Correct answer: A. Mitochondria - Produces cellular energy in the form of ATP
- A. Mitochondria - Produces cellular energy in the form of ATP
- B. Golgi apparatus - Modifies, sorts, and packages proteins and lipids
- C. Lysosomes - Contains digestive enzymes for breaking down waste
- D. Endoplasmic reticulum - Synthesizes proteins and lipids
Explanation
The labelled organelle is the mitochondria, which is the site of cellular respiration and ATP production, making it the 'powerhouse' of the cell. It converts energy stored in food molecules into ATP, which is used to power various cellular processes. The other options describe organelles with different functions: the Golgi apparatus is involved in processing and packaging proteins and lipids, lysosomes contain enzymes for digestion, and the endoplasmic reticulum is involved in protein and lipid synthesis.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
