Garstang's Auricularia hypothesis suggests that ancestral vertebrates may have evolved from urochordate larvae.
What is Garstang's Auricularia?
The auricularia hypothesis, proposed by Garstang was an attempt to explain how the chordate body plan originated from a deuterostome common ancestor by emphasizing the significance of changes in larval forms. According to the Garstang Hypothesis, development of sexual maturity in a non-metamorphosing lineage of tunicates might provide the immediate proto-chordate ancestors of more typical chordates.

1983-1984 was when it was discovered
The Krebs cycle. The steps are
1. Glycolysis
2. Krebs Cycle
3. Electron transport chain.
The Calvin cycle is in photosynthesis.
B. Cell wall and a central vacuole
The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright. Animal cells are more fluid.
The central vacuole is a large region in the cell that stores nutrients and fluids. Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
Hope this helps!!
