(A) The structure is the cell wall. The cell wall protects the cell from damage. It is also there to make the cell strong, to keep its shape.

(B) Structure Z is a chloroplast. Chloroplasts work to convert light energy of the Sun and turn it in to sugars that can be used by the cells. This process is also called photosynthesis.

(C) Since chloroplasts create sugar for a plant cell, fungi has mitochondria. Fungi uses mitochondria which create ATP (also know as Adenosine Triphosphate) which is energy. Therefore, fungi doesn’t need chloroplasts.

Y- Cell membrane and holds the cell together
Z- Chloroplast, makes sugar from CO2, water, and the sun

Fungi don't need chloroplasts, as they behave like heterotrophs, feeding on detritus (dead stuff).

The viruses are organisms
Zepler [3.9K]
Virus is a microscopic particle that can infect the cells of a biological organism.

Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.

At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.

They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).

A virus that infects bacteria is known as a bacteriophage, often shortened to phage.

The study of viruses is known as virology, and those who study viruses are known as virologists.

It has been argued extensively whether viruses are living organisms.

Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.

They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.

A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.

Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.

Serious diseases such as Ebola, AIDS, bird flu and SARS are all also caused by viruses.

Ancient photosynthetic prokaryotes were very important in the history of life because theya. produced the oxygen in the atmosphe
OLga [1]

Answer:

a) produced the oxygen in the atmosphere

Explanation:

  • Prokaryotes are likely to first form of life on earth and they existed billions of years ago before animals and plants.
  • As these prokaryotes can do photosynthesis so there most important function is produce oxygen in atmosphere for the evolution of aerobic life.
  • At that time the conditions were harsh on earth so these prokaryotes are used to survive under earth like in oceans. They first produce oxygen in oceans.
  • In eukaryotes photosynthesis emerge by endosymbiosis with photosynthetic prokaryotes.
