How many organs are in the human body?

There are around 78-79 organs in the human body! Sorry it’s not precise it’s a widely controversial topic due to some people believing that something isn’t classified as an organ so I can’t say for sure!

rjkz [21]

Answer:

  • Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

  • Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

                       <u>   Animal Cells                              Vegetable Cells</u>

Cell wall                          NO                                             YES

Vacuoles       YES, Small and more than ones     YES, Only one and big

Chloroplast                      NO                                        YES

Plasmatic membrane       YES                                            YES

Mitochondria                       YES                                         YES

Lysosomes                       YES                                           YES

Endoplasmic reticulum      YES                                           YES

Golgi apparatus                   YES                                           YES

Cytoplasm                            YES                                           YES

Ribosome                             YES                                           YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

<u>Cell wall</u>: A rigid structure that provides support and protection.

  • Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
  • Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

<u>Chloroplast:</u> these are organelles that accumulate chlorophyll.

  • Animal cells do not have chloroplasts because they do not photosynthesize.
  • Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

<u>Vacuoles</u>:

  • Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.
  • Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.

Which organelle does the skeletal system connect to and why?
Snezhnost [94]

Answer:

Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.

suter [353]

Answer:

D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Explanation:

During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.
