Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic
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.

Isovolumetric relaxation and ventricular filling (two phases of the cardiac cycle) take place during __________. view available
jekas [21]
Isovelumetric relaxation and ventricular filling take place during Ventricular diastole.. Both occur during ventricular diastole when the ventricles are not actively contracting and ejecting blood. Ventricular diastole is the period during which the two ventricles are relaxing from contortions of contraction, then dilating and filling; atrial diastole is the period during which the two atria are relaxing, dilating, and filling.

Which structure anchors the chordae tendinae of the atrioventricular valves?
lidiya [134]
Answer: papillary muscle

Chordae tendinae is a connective tissue that used to prevent the heart valve to be flapped away. It like a string that connected into the valve and makes it look like a kite. Papillary muscle is the part that anchoring it to the heart wall.
