Eukaryotic cells are more complex than bacteria and they have a nucleus. They also contain organelles such as mitochondria, chloroplasts, and the Golgi apparatus. However, eukarya can be unicellular or multicellular organisms whereas bacteria are always unicellular. Eukarya species include animals, plants, fungi, and protists while bacteria includes all prokaryotes that do not belong to any other group of organism on this list.
Bacteria are prokaryotic cells that can be found all across the world. They are usually microscopic, one-cell organisms that exist in water, soil, and on people’s skin. Eukarya are more complex organisms with a nucleus located in the cell’s cytoplasm. These organisms have different types of organelles within them such as mitochondria or chloroplasts which help to provide energy for the organism.
Comparison between Bacteria and Eukarya
|Parameters of Comparison||Bacteria||Eukarya|
|Cell||Bacteria are prokaryotic cells||eukarya are eukaryotic cells|
|Mitochondria||Not found it||Eukarya contain mitochondria|
|Orgeneless||bacteria do not have these organelles||Eukarya have organelles that help them to carry out metabolic processes|
|System||Bacteria are prokaryotic||eukarya are more complex and contain a nucleus|
|Helpful||Bacteria can be either harmful or beneficial to humans||eukarya are only helpful|
What is Bacteria?
Bacteria are tiny, single-celled organisms that play a vital role in the environment and human health. There are countless different species of bacteria, and they can be found almost everywhere on Earth. Bacteria are essential for many processes, including digestion, nutrient cycling, and soil formation. In addition, certain types of bacteria can cause disease. Learning about these fascinating creatures is a key step in taking care of our planet and ourselves.
Bacteria are microscopic organisms that can be found almost everywhere. They live in the soil, water, and our food. Bacteria grow quickly and double their population every 20-40 minutes! Some bacteria cause disease while others help us with digestion and other bodily functions. Read on to find out more about these fascinating little beings that we encounter every day.
What is Eukarya?
Eukarya are the most complex form of life on Earth. They have a nucleus, membrane-bound organelles, and cell walls with cellulose. The three main types of Eukarya are algae, fungi, and animals. All living things that aren’t bacteria or archaea are eukaryotes because they share this common trait. This includes all plants and animals including humans.
Eukaryotes make up more than 90% of all species on earth which makes them the most diverse type of organism in our environment. These organisms live in every habitat imaginable from deserts to rain forests Although there is no one universal definition for what constitutes a eukaryote since they come in many different shapes and sizes it’s possible to define them based on some common characteristics.
10 Differences Between Bacteria and Eukarya
1. Bacteria are prokaryotic cells while eukarya are eukaryotic cells.
2. Eukarya contain mitochondria, which are not found in bacteria.
3. Bacteria have a cell wall while eukarya do not.
4. The nucleus of a eukaryotic cell contains DNA whereas the bacterial chromosome is circular and lacks any nucleolus or nuclear envelope.
5. Eukarya have organelles that help them to carry out metabolic processes; bacteria do not have these organelles.
6. Bacterial protein synthesis occurs by ribosomes attached to the endoplasmic reticulum, whereas protein synthesis in eukarya cells takes place at the Golgi apparatus.
7. Bacteria are prokaryotic, while eukarya are more complex and contain a nucleus.
8. Eukarya have cells walls made of cellulose and bacteria do not.
9. Bacteria can be either harmful or beneficial to humans; eukarya is only helpful.
10. There is an unequal distribution of bacteria in the human body, with most residing in the gut.
Interesting Statistics or Facts of Bacteria
1. There are more bacteria cells in your body than there are in human cells.
2. Bacteria is responsible for the production of many vitamins, like Vitamin K and biotin.
3. The majority of bacteria cannot be seen with the naked eye.
4. Some strains of bacteria can cause illnesses, such as Staphylococcus Aureus or Salmonella enterica.
5. Antibiotics don’t kill all types of bacteria – they only work on certain strains.
6. Certain types of antibiotics can even allow non-resistant strains to become resistant over time.
Interesting Statistics or Facts of Eukarya
1. Eukarya is the largest domain of life on Earth.
2. The word eukaryote means “true nucleus”.
3. There are about 250 different types of eukaryotes, including animals and plants.
4. All living things that have a membrane-bound nucleus in their cells are classified as Eukarya.
5. The word eukaryote comes from the Greek words for “well-rounded” or “true nucleus”.
6. A cell wall may be present but not necessary for classification as a Eukarya (eucalyptus).
Bacteria cells are less complex than eukaryotes. They have a cell wall, but no nucleus or mitochondria. Eukarya organisms have all of these structures in their cells. Bacteria reproduce through binary fission while some eukarya can also reproduce sexually with the fusion of two haploid gametes to form a diploid zygote that develops into an embryo and then an adult organism.-Bacterial DNA is organized as one long circular molecule whereas eukaryotic DNA is found on chromosomes inside the nucleus.-Eukaryotes have more differentiated organelles that perform different functions such as ribosomes for protein synthesis, lysosomes for digestion, peroxisomes for fat metabolism, etc.
