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.

If a cell culture contains 400 cells/ml at time = 0 and it has a generation time of 30 minutes, how many cells (cells/ml) will b
Semmy [17]

Answer:

The answer to your question is: after two hours there will be 6400 cell/ ml

Explanation:

Data

Bacteria t = 0; 400 cells/ml

generation time = 30 minutes

# cells after two hours = ?

                                 # of bacteria               time

                                     400                            0

                                      800                         30 min

                                   1600                           60 min

                                   3200                           90 min

                                   6400                          120 min

Describe what must come together in order for atp to be made
gizmo_the_mogwai [7]
To make ATP, cells must join together ADP & a phosphate using energy from food. A phosphate is removed from an ATP molecule in order to provide energy for the cell. Thus, the ATP molecule turns into an ADP molecule. We eat food which gives us energy to add another phosphate group to the ADP molecule, turning it into an ATP molecule. The cycle then begins again.
