Answer:
Eukaryotes:
-Organisms with a well defined nucleus are known as eukaryotes. such cells are called as eukaryotic cells.
- Their nucleus is enclosed within the nuclear membrane.
- They do not posses a mitochondria.
- The cell wall is the outer most layer of a eukaryotic cell (only plant cells have a cell wall)
- The cells are divided by a process called mitosis.
Eg: Plants, Animals.
Prokaryotes:
- Organisms without a well defined nucleus are known as prokaryotes. Such cells are called as Prokaryotic cells.
- They lack nuclear membrane.
- Mitochondria, Golgi bodies, chloroplast and lysosomes are absent.
- The genetic material (DNA) is present on the chromosome.
Eg: Every organism coming under the kingdom monera.

Answer:
The amount of oxygen in the atmosphere would decrease.
Explanation:
If a massive toxic spill kills off half the population of photosynthetic plankton in the ocean. That would mean that only half of the original population of plankton will remain. Photosynthetic plankton consumes carbon dioxide from the atmosphere during photosynthesis to produce energy and releases oxygen.
The life cycle stages of a plant would be seeds → germination→growth→maturity→pollination→fertilisation→seeds etc etc.
so I would say the life cycle stages not found in animals would be either pollination or germination.
