1. Describe how bacterial cells compare to onion cells.
Solution
Plants cells are multi-cellular organisms composed of eukaryotic cells, while bacteria are single-
cell prokaryotic organisms. Each eukaryotic cell of a plant or animal includes a central nucleus
containing DNA and membrane-bound organelles, such as endoplasmic reticulum and
mitochondria. A bacterial cell has no nucleus or membrane-bound organelles. prokaryotes have
circular DNA, which is exposed to the cytosol fluid of the cellular environment and concentrates
in an area known as the nucleoid. Within the cytosol environment of both eukaryotes and
prokaryotes are ribosomes, which are responsible for producing the polypeptide chains of
proteins. In bacterial cells, ribosomes are 70s, while eukaryotic plant and animal cells have
larger, 80s ribosomes. These 80s ribosomes float within the cytosol of the cell and adhere to the
rough endoplasmic reticulum unique to eukaryotes. The mitochondria of eukaryotes do contain
70s ribosomes within their mitochondria. a prokaryotic bacterium invaded an early-form
eukaryotic cell, which gave rise to mitochondria. Bacteria cells divide by way of binary fission
and are asexual. Eukaryotes, however, divide cellularly via mitosis and reproduce sexually
through the process of meiosis. An onion is a multicellular (consisting of many cells) plant
organism. As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane,
cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm.
The vacuole is prominent and present at the centre of the cell. It is surrounded by cytoplasm. The
presence of a cell wall and a large vacuole are indicators that help identify plant cells, such as
seen in the onion peel.
