How a plant cell and all its organelle functions to help a tree or plant survive, adapt and reproduce?
ArbitrLikvidat [17]

A plant cell is illustrated as a cell that comprises nucleus and organelles enveloped by a rigid and thick cell wall. The functions of the organelles are as follows:  

1. Cell membrane: It safeguards the cell and monitors the molecules leaving and entering the cell.  

2. Cytoplasm: It assists in holding the organelles of the cells in place.  

3. Cell wall: It is the main safeguarding barrier of the plant cells.  

4. Chloroplast: It transforms sunlight into energy by a procedure known as photosynthesis.  

5. Cytoskeleton: It provides structural support for the cell.  

6. Ribosome: It builds protein for the cell to utilize.  

7. Nucleus: It stores the DNA and coordinates the activities of the cell, mainly it acts as brain.  

8. Mitochondria: It convert oxygen and nutrients into energy.  

9. Lysosomes: It dissociate waste into basic components for other organelles to function.  

10. Endoplasmic reticulum: It transports and manufactures chemical components to and from the nucleus.  

11. Peroxisomes: It digests toxic substances in the cell.  

12. Golgi Apparatus: It transforms proteins and fats built in the cell and transports them outside the cell or prepares them for storage.  

13. Plasmodesmata: It allows communication and transport of substances to the nearby cells.  

14. Vacuole: It stores waste components and sustains the level of pH of the cell.  

15. Vesicle: It conducts substances within the cell and help in storing enzyme s.

Describe the movement of ions that causes an action potential to occur.
AveGali [126]
Okay well the signal or the movement coming through the neuron(and its axon)  is about the ions. The ion is a charged like particle, such as Na+ (If you remember that). Na+ is a sodium ion. So most of those ions I was talking about before just simply flow in or out of the cell. I hope this helps! <3

Transposable elements are DNA sequences that Group of answer choices are not coded to produce proteins. occur only on the X and
Lerok [7]

Transposable elements are DNA sequences that contain numerous point mutations. Thus, option "4" is correct.

<h3>What are Transposable elements?</h3>

Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighbouring pieces of DNA, mobile elements move from one place to another causing many changes or mutations.

When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.

On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match.

This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

Thus, option "4" is correct.
