Do plants and animals have a rough ER?
Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.
What is the function of RER and SER?
Difference between Smooth and Rough Endoplasmic Reticulum
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| It participates in the synthesis of enzymes and proteins. | Synthesises glycogen, lipids and steroids. |
| It helps in the formation of lysosomes. | Gives rise to Spherosomes/ Oleosomes |
What is the main function of the rough endoplasmic reticulum?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Do bacteria have ER?
No, bacteria do not have endoplasmic reticulum because bacteria is a prokaryotic organism that lacks member bound organelles such as the nucleus, endoplasmic reticulum, mitochondria, lysosomes, Golgi apparatus, etc.
What are the similarities between bacteria and animal cells?
| Similarities DESCRIPTION | Bacterial Cells | Animal Cells |
|---|---|---|
| 3. Structures to produce energy for cell- Cell Respiration | No-occurs near cell membrane | Yes- in organelle called mitochondrion |
| 4. Structures that make proteins and enzymes for the cell | Yes-poly- (many) ribosomes | Yes- endoplasmic reticulum (organelle) |
| 5. Cytoplasm | Yes | Yes |
What is the difference between an animal cell and a bacterial cell?
Bacterial and animal cell are two types of living cells. Bacterial cell belongs to kingdom Monera and animal cell belongs to the kingdom “Animalia”. Bacteria are unicellular organisms (consist of a single cell or they exist as a single cell) and animals are multicellular organisms as they are made of many cells.
Is bacteria an animal or plant?
In answering the question, are bacteria animals or plants, we can deduce that bacteria are unique organisms and deserve their own separate classification system. Bacteria are neither animals nor plants.
What are the 7 types of bacteria?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.
Is a germ an animal?
Germs are tiny animals which are so small they cannot be seen without the help of a special instrument called a microscope. The microscope allows the germs to be seen by making them look a lot bigger. Many of these germs will cause disease in humans and other animals.
What was the first germ-free animal?
guinea pigs
Are germs alive?
Actually, germs are tiny organisms, or living things, that can cause disease. Germs are so small and sneaky that they creep into our bodies without being noticed. In fact, germs are so tiny that you need to use a microscope to see them.
What is the dirtiest part of a school?
Here are 10 of the germiest places to watch out for during the school year.
- Backpacks. Before tossing a backpack onto the kitchen counter after a school day, consider where it’s been.
- Gym class.
- School pools.
- Mouth Guards.
- Portable texting devices.
- Computer Lab.
- Cafeteria.
- Homeroom.
Do germs have brains?
Bacteria do not have brains or other organs. Even their one cell looks much simpler than one of our own cells. Even so, bacteria can defend themselves from viruses a lot like we do. Then the bacteria are protected from infection.
How long do germs live on your hands?
Flu germs live for about 5 minutes on skin This means that if you sneeze into your hands, this will cause greater contamination than simply touching something like a doorknob. The best way to get rid of germs on your hands is to wash with soap and water for at least 20 seconds.
What percent of germs does hand washing kill?
Lathering up In studies, washing hands with soap and water for 15 seconds (about the time it takes to sing one chorus of “Happy Birthday to You”) reduces bacterial counts by about 90%. When another 15 seconds is added, bacterial counts drop by close to 99.9% (bacterial counts are measured in logarithmic reductions).
Do germs like water?
Bacteria Need a Source of Water Single-celled bacteria lack that ability, so they must rely on finding enough available water in their environment to through their cell membranes. Many bacteria can survive for extended periods without moisture, but without it they can’t grow and reproduce.
How long do germs live on a toilet seat?
The flu virus can live up to two or three days on nonporous surfaces like a toilet seat . It can also survive for that amount of time on your phone, remote control, or a door handle.
Is it safe to sit on public toilet seats?
Many disease-causing organisms can survive for only a short time on the surface of the seat, and for an infection to occur, the germs would have to be transferred from the toilet seat to your urethral or genital tract, or through a cut or sore on the buttocks or thighs, which is possible but very unlikely.
Can you get a STD from urine on a toilet seat?
Good news first. The first thing you need to know about sitting on a dirty toilet seat and peeing is that it may not cause diseases like chlamydia, herpes, or any other sexually transmitted diseases or genital infection.
Can I get HPV from a toilet seat?
Even if a person delays sexual activity until marriage, or only has one partner, they are still at risk of HPV infection if their partner has been exposed. You cannot get HPV from: Toilet seats. Hugging or holding hands.
What kills HPV virus?
Preliminary testing shows that a shiitake mushroom extract shows promise in curing HPV. An early, pre-clinical trial has shown that Active Hexose Correlated Compound (AHCC), an extract from shiitake mushrooms, can kill the human papillomavirus (HPV), the most common sexually transmitted infection in the U.S.
Is HPV contagious for life?
Depending on the type of HPV that you have, the virus can linger in your body for years. In most cases, your body can produce antibodies against the virus and clear the virus within one to two years.
Can you catch HPV Non sexually?
You can be infected with HPV without being sexually active – as HPV spreads easily through skin-to-skin contact, it is possible to be infected with HPV without having sex. Prolonged contact with infected skin, such as holding hands, may cause transmission of the virus.
Does HPV mean my husband cheated?
HPV is very common, and if you’re sexually active, it’s one of the risks you face. It doesn’t mean that you or your partner (or previous partners) did anything wrong. Partners tend to share strains of the virus between them, which means it’s almost impossible to know where the infection started.
