If all plants were to die, photosynthesis wouldn't occur and that would affect the ecosystem because every other biotic organism would not have oxygen to breathe.

Answer:

All living things are made of cells

Cells form from previously existing cells

Explanation:

According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.

How do you write 2-3 paragraphs on evolutionary history/advances from the monerans to protists to fungi?
Lyrx [107]

Kingdom Monera was the oldest kingdom of living organisms. The organisms in the kingdom were simple, single celled and their cellular organelles were not covered by membranes. Prokaryotic bacteria were the first known Monerans. However, scientists think that Monerans were evolved into more complex eukaryotic organisms (Protists) with the passage of time.  

But how did Monera (Prokaryotes) was evolved into Protista (Eukaryotes)?

  • Monerans to Protists

Protista are eukaryotes, unicellular or simple multicellular organisms.Many theories were proposed for this evolution, but one that makes most sense was endosymbiotic theory. According to this, the first eukaryotic cells were evolved when two prokaryotic cells existed in an endo-symbiotic relationship. Larger prokaryotic cells engulfed smaller prokaryotic cells. The smaller cells got shelter and nutrients from larger cells and both co-existed in a mutualistic relationship. Both cells eventually evolved into organelles and got never aparted. This is how more complex organisms’ protists were evolved from simple monerans. It was a gradual process and took millions of years.

  • Protists to Fungi

The earliest fungi were single-celled organisms that contain a flagella to move from one place to another. Recent studies indicate that fungi belong to a group of organisms which were evolved from protists over the course of time. These studies are based on the nucleotide sequence of fungi that matches to a large extent with old protists. It is estimates that fungi evolved 600 million years  or even before.

Use the information in the chart to determine if it describes a living object. composed of cells complex chemical activities com
Solnce55 [7]

The object is a living thing; option B

<h3>What are living things?</h3>

Living things are things that have life in them.

The basic activities of living things are given as follows:

  • movement
  • reproduction
  • nutrition
  • Irritability
  • growth
  • excretion
  • respiration

Considering the information in the chart about the object:

  • composed of cells
  • complex chemical activities
  • breaks down food to get energy

These are characteristics of living things, therefore, the object is living.

In conclusion, living things carry out the activities of life.
