List five cell organelles and describe their function.

Answers

Answer 1

Answer:

Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.

This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.

Mitochondria are some of the largest organelles within a cell.

Compared to some of the other organelles, mitochondria contain DNA which makes them semiautonomous. Mitochondria also contain a double-membrane with the inner membrane folding to form cristae.

Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen. Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.

The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.

As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change.

The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).

Found in eukaryotic cells, Endoplasmic reticulum (ER) is the organelle that forms an interconnected network of flattened sacs (cisternae). Like some of the other organelles found in eukaryotes, ER is enclosed in a membrane. The ER is divided into two regions that vary in structure and function.

These include:

Smooth endoplasmic reticulum - The smooth ER is named so because it lacks a ribosome on its surface. As a result, it is more smooth in appearance as compared to the rough ER. It is involved in the synthesis of lipids (e.g. phospholipids) and carbohydrates that are used to build the cell membrane.

There are no known effects and scientific evidence that proves GMOs are harmful to humans. GMOs have edited genes that help them to be resistant against a myriad of diseases, environmental conditions, and change "ugly" traits (ie. shortness, too skinny fruit, etc). The process of editing genes is like the recombination of DNA by human intervention. You edit out what's ugly and reinforce what is needed without changing the physical make-up of the organism.

Example

Corn is very known to have a GMO. It also has different varieties that are products of selective breeding, a type of narrowing down the best traits from two pure-bred individuals.

Celeste was tested for AT, and the test showed that she has zero AT alleles. Based on your work for Checkpoint 4-3, what is the probability that C&G have a child that has zero AT alleles?

Answers

The probability of the offspring of C&G to have zero AT alleles depends on if her husband G has AT alleles or not.

What is the principle of inheritance?

The principle of inheritance suggests that characters are randomly inherited by offspring from parents and that the dominant trait always appear in the offspring when present.

Genes contains the information for making the proteins for any trait.

Genes exists in alternative forms know as alleles.

If Celeste has zero AT alleles, the probability of her offspring to have AT alleles depends on if her husband G has AT alleles as well.

If G has zero AT alleles, the probability of C&G having a child that has zero AT alleles is 1.

However, the probability reduces if G has any AT alleles at all.
