Question

rhizopus differs from bacteria as the former has example cell wall,
70s ribosomes, reserve food material as starch​

Answer 1

Prokaryotic cell Eukaryotic cell

1. They are generally small in size (1-10 micrometer). 1. Eukaryotic cells are comparatively larger in size.

2. Nuclear matter is undefined without any nuclear membrane and is called as nucleoid. 2. A true nucleus with nuclear membrane is present.

3. Single chromosome is present as genetic material. 3. More than one chromosome is present.

4. It lacks any membrane bound organelles, i.e., ER, Golgi body, mitochondria etc, are absent. 4. It is characterized by presence of membrane bound organelles.

5. 70S type ribosome is present. 5. 80S type ribosome is present.

6. Cell division occurs by fission, budding or fragmentation. 6. It exhibits mitosis and meiosis as cell division processes.

Answer 2

This is the representation of the difference between eukaryotic cells and prokaryotic

About prokaryotic cells:

• Prokaryotic cells are the earliest single-celled microbes on Earth.
• Prokaryotes include bacteria and archaea.
• Cyanobacteria are prokaryotes that perform photosynthesis.
• Because a prokaryotic cell has only one membrane, all processes occur in the cytoplasm.
• Prokaryotic cells lack organelles, do not have nuclei, and are much smaller than eukaryotic cells.
• Every prokaryotic cell is protected by a cell wall.
• Many also have a polysaccharide-based capsule or slime layer.
• Prokaryotes frequently have surface protrusions (appendages).

About Eukaryotic cells:

• Eukaryotes are organisms that have cells with a nuclear envelope surrounding their nucleus.
• They are organisms that belong to the Eukaryota or Eukarya class.
• The eukaryotic domain is one of three domains of life, the other two being the bacterial and archaeal domains.
• The nucleus, mitochondria, and endoplasmic reticulum are membrane-bound organelles found in eukaryotic cells.
• Eukaryotic cell-based organisms include protozoa, fungi, plants, and animals.
