Biology

Answer :

The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.

Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.

Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.

The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.

The eukaryotic cells sizes are more than prokaryotes like bacteria.

Plasma membrane - protect cell from it's surroundings. In both kinds of cells.


Cytoplasm - supports rounded cell structure, within it are all the organelles. Contains chemicals needed by the cell. In both kinds of cells.


Nucleus - contains DNA and is the control center of the cell. In both kinds of cells.


Nuclear envelope - surrounds nucleus, makes sure important molecules (DNA) stay within the nucleus. In both cells.


Nucleolus - makes ribosomes. In both cells.


DNA - genetic information for development and function. In both cells.


Rough ER - produces proteins. In both cells.


Smooth ER - makes and stores lipids (fats). In both cells.


Golgi body - sort and process macromolecules (proteins, lipids, etc). In both cells.


Ribosomes - makes proteins. In both cells.


Vacuoles - very large in plants, a storage center. In both cells.


Lysosome - digests and removes wastes. In both cells.


Mitochondria - energy powerhouse, produce ATP energy. In both cells.


Cytoskeleton - shapes, supports, and facilitates movement. In both cells.


Centrioles - cell division (form spindle fibers). Only in animal cells.


Cilia - movement for microorganisms. Only in animal cells.


Chloroplasts - photosynthesis, helps absorb sunlight and make food for the plant. Only in plant cells.


Cell wall - strength, structure, filters molecules going in and out of the cell. Only in plant cells.


Central Vacuole - holds materials and wastes, helps maintain proper pressure within the cell. Only in plant cells.


Hope this helps!

What is the biggest problem with invasive species in their new location
mihalych1998 [28]

Answer:

Because they are not native to a location, they can quickly dominate the wildlife.

Explanation:

  • They may not have any predators to keep them in check.
  • They basically destroy a food chain which can have a domino affect of killing off other native species that require certain food to survive.
  • Some might spread disease.
