So animal cells can have various shapes, but plant cells only havethe shapes of their cell walls. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants tohave rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change siz
Exactly why plant cell have wall and animal cell don't :-Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.
On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any external Injuries.
This was the all information I had thank you.
Answer:
The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.
Explanation:
The picture is given in the question is an aerial view of the fault line of San Andreas.
A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.
Observation:
- A complex zone of crushed and broken rock
- Many smaller faults branch
Answer:
DNA to RNA to protein.
Explanation:
Central dogma in biology was given by Crick in 1957. The central dogma explains the flow of genetic information in the cells.
According to the central dogma, DNA can multiply and increase its number by the process of replication. The information from DNA is changes to RNA by the process of transcription. The expression of protein product expression occur from the RNA by the process of translation. Hence, the information travels from DNA to RNA to protein.
Thus, the correct answer is option (2).
Answer:
fertilization is the process of fusion of gametes from two parents. gametes are produced as a result of meiosis in which crossing over and recombination produces new combinations of genes and sometimes mutations are also occur which also leads to development of unique characteristics.
this is the main reason that kids from same parents are genetically unique.
Explanation:
We can tell from their structure that fatty acids are a good source of energy because of their large number of carbon-hydrogen and carbon-carbon bonds that they contain. Most fatty acids have straight chain compounds with an even number of carbon.
