11 Questions
Explain the difference between how fungi and animals obtain nutrients.
Fungi obtain nutrients by breaking down organic matter, while animals obtain nutrients by consuming other organisms or plant matter.
Describe the main function of vaccines in protecting against infections.
Vaccines stimulate the immune system to produce antibodies that can recognize and fight off disease-causing microbes in the future.
Differentiate between prokaryotic and eukaryotic cells.
Prokaryotic cells do not have a defined nucleus, while eukaryotic cells have a nucleus where the genetic material is located.
What is the role of antibodies in the immune response triggered by vaccines?
Antibodies produced in response to vaccines can recognize and fight off disease-causing microbes in the future.
Explain why understanding the differences between animal and plant cells is crucial in biology.
Understanding cell structure helps in comprehending the unique functions and characteristics of animals and plants.
What organelles are present in plant cells but absent in animal cells?
Chloroplasts, cell wall, plasmodesmata, large central vacuole
Why do plant cells have chloroplasts while animal cells do not?
Plant cells need chloroplasts for photosynthesis to convert sunlight into glucose.
What is the main difference between prokaryotic and eukaryotic cells?
Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.
Which type of cell has a more complex structure, prokaryotic or eukaryotic?
Eukaryotic cells
What are some characteristics shared by all living things?
Composed of cells, require nutrients and energy, respond to stimuli, able to grow and reproduce
Why do animals not have chloroplasts in their cells?
Animals obtain their energy from food and do not have the ability to photosynthesize.
Study Notes
Biology
Animal vs Plant Cells
Animal cells and plant cells differ in their structure and organelles. Animal cells have centrosomes (or a pair of centrioles) and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and a large central vacuole, whereas animal cells do not. Chloroplasts are present in plant cells because they need to perform photosynthesis, a process that converts sunlight into glucose. This glucose is then used by the mitochondria to produce energy for the plant cell. Animal cells do not need chloroplasts because they obtain their energy from food and do not have the ability to photosynthesize.
Prokaryotic vs Eukaryotic Cells
Prokaryotic cells, such as bacteria, lack a nucleus and other membrane-bound organelles. They have a less complex structure compared to eukaryotic cells, which are found in all other organisms, including plants and animals. Eukaryotic cells have a more complex structure, with a nucleus and various membrane-bound organelles, such as mitochondria, ribosomes, and endoplasmic reticulum.
Characteristics of Living Things
All living things share certain characteristics, such as being composed of cells, requiring nutrients and energy, responding to stimuli, and being able to grow and reproduce. However, different types of organisms have different characteristics. For example, plants can photosynthesize and make their own food, while animals cannot. Fungi, on the other hand, obtain nutrients by breaking down organic matter in their environment.
Microbes vs Vaccines
Microbes are tiny organisms, such as bacteria and viruses, that can cause diseases in humans and other organisms. Vaccines, on the other hand, are designed to protect against infections by introducing a harmless form of the disease-causing microbe into the body. This stimulates the immune system to produce antibodies, which can then recognize and fight off the actual disease-causing microbe if it is encountered in the future.
In conclusion, biology is a multifaceted field that studies the structure, function, and behavior of living organisms. Understanding the differences between animal and plant cells, the characteristics of living things, and the role of microbes and vaccines in our health is crucial for appreciating the complexity and diversity of life on Earth.
Explore the differences between animal and plant cells, the characteristics shared by living organisms, and the role of microbes and vaccines in biology. Learn about prokaryotic vs eukaryotic cells and how living things obtain energy and nutrients through different processes.
