There are many ways in which the study of unicellular organisms contributes to our understanding of multicellular organisms.
Exploring unicellular organisms can provide valuable insights into various aspects of the biology of more complex multicellular organisms. For instance, understanding the mechanisms by which single cells sense and respond to their environment, communicate with each other, differentiate, and specialize can help us grasp the fundamentals of development, cell signaling, and gene regulation that underlie the formation and function of tissues, organs, and organisms.
Moreover, studying the evolution, diversity, and ecology of unicellular life can inform us about the origins and adaptations of eukaryotic cells, including the emergence of symbiosis, predation, and cooperation among cells.
Overall, unicellular organisms represent a fascinating and accessible model system to investigate biological phenomena that are relevant to both basic research and practical applications in fields such as medicine, biotechnology, and ecology.

Unicellular organisms significantly contribute to the study of multicellular organisms. This is because unicellular organisms do not possess complex body types like that found in multicellular organisms. Due to the presence of a single cell, the study of cellular structure and functions becomes easy.
How is a multicellular organism formed from a single cell?Every multicellular organism, whether a plant or an animal starts its life with a single cell. The life of a multicellular organism begins with a fertilized egg which is a cell. This cell divides repeatedly and differentiates into many different kinds of cells.
Different patterns of cellular arrangements form a complex organism. This pattern is determined by the genome and the genome of every cell is identical. The variety in the cell types is displayed because of the expression of different sets of genes.

Explain how each type of infectious agent (bacteria, virus, fungi, and parasite) affects the body.
Answer:
bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.
Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.
fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.
Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.

Students in a Biology class were formulating an argument about a cell they viewed under the microscope. Half
of the class argued it was a plant cell and the other half argued in favor of an animal cell. Below is the image the
students saw under the microscope. Which argument is supported by the image?
A. The students who said the plant cell are correct because there are chloroplasts
B. The students who said a plant cell are correct because there are mitochondria present.
C. The students who said animal cell are correct because there are chloroplasts present.
D. The students who said an animal cell are correct because there are mitochondria present.
Answer:
the answer would be A
Explanation:
Animal cells are oval and egg shaped so we can cancel out c and d
A is the correct answer because we can see green dots within the structure. Chloroplasts contain a green pigment called chlorophyll. This green pigment makes the chloroplast and the structure green (as we can see in the picture). Photosynthesis occurs in the chloroplasts, and it is where the plant gets its glucose from

why are viruses not regarded as true living cells?
Explanation:
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.
What is environment?Environment is defined as a compilation of all the factors living and nonliving and the outcomes they have on human life. Due to their ties to the forest, its plants, wildlife, water, and air. The air is filtered and hazardous gases are absorbed by the forest and trees. Plants filter water, lessen the likelihood of flooding, preserve the natural equilibrium, and do many other things.
Viruses are more like robots than actual living things, even though they do replicate and adapt to their surroundings. The viruses are thought to be dead in their natural habitat since they lack any cell-like properties. However, inside the host cell, the viruses employ the host's technological infrastructure to carry out all necessary tasks including reproduction.
Thus, viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

Explanation:
Answer:
Mendel studied the genetics of pea plants.
Explanation:
Mendel looked at the pea plants in his monastery garden to determine genetics. He found that some plants had white flowers, while some did not, and he used that discovery to determine the genetics of the plants.
Which types of plant cells must receive glucose from other plant cells?
Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
The type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.
Photosynthesis is a group of metabolic reactions by which plant cells generate simple carbohydrates (i.e., glucose) and oxygen by using the energy from the sun, carbon dioxide and water.In consequence, non-photosynthetic cells cannot produce glucose and thus need to receive this nutrient from photosynthetic cells.An example of non-photosynthetic cells is the root cells found underground.In conclusion, the type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.
What are the major features of ants ?Ants belongs to Formicide family which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.
The diversity of ants is every where except Antarctica.
The body has three parts such as a head, a meso-some and metasoma or gaster.
Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.
The reproduction in which young, queens fly during mating time, fertilize with male, this flight is called as nuptial flight.
Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.
Thus, option D is correct.
