B1 Cell Biology Quiz

Prokaryotes are simple cells that lack a nucleus and membrane-bound organelles. They reproduce by binary fission, not meiosis.

Inside a cell, the different parts are called organelles, which are specialized subcellular structures with specific functions. Cells, tissues, and organs are at higher levels of organization in biological systems and do not refer to the different parts inside a cell.

The correct answer provides the subcellular structures specific to a plant cell and their functions. The incorrect answers mention other subcellular structures found in cells in general but are not unique to plant cells. Therefore, they are not relevant for labeling the subcellular structures of a plant cell on the diagram.

Microscopes are scientific instruments used to magnify and visualize small objects, such as cells, that are not visible to the naked eye. They are commonly used in biology and medicine for research and diagnosis.

Light microscopes are scientific instruments used to view objects at a microscopic level and are commonly used in biology and research to study cells and their structures.

The correct answer highlights the two main limitations of a light microscope, which are limited magnification and resolution. The incorrect answers provide different scenarios that do not align with the typical disadvantages associated with light microscopes.

Electron microscopes utilize a beam of electrons instead of a beam of light, allowing for higher resolution and magnification in imaging compared to traditional light microscopes.

Electron microscopes have the advantage of achieving much higher magnification and resolution compared to light microscopes, allowing for detailed examination of samples at a microscopic level.

The correct formula for calculating the magnification of a microscope is by dividing the image size by the actual size. This ratio helps determine how much larger an object appears when viewed through the microscope.

The subcellular structures of a bacterial cell differ from eukaryotic cells in several ways. Bacteria lack a true nucleus, Golgi Apparatus, and Endoplasmic Reticulum. Ribosomes, Vacuoles, and Lysosomes are also not typically found in bacterial cells. Additionally, Cellulose, Starch Granules, and Flagella are not prominent structures in bacterial cells.

Preparing a slide for microscopy involves specific steps to ensure the specimen is visible and protected. Adding water helps in providing a clear view, iodine solution acts as a stain, and a cover slip protects the specimen from damage.

To use a light microscope to look at a slide, it is important to follow the correct steps outlined in the answer. The incorrect answers provided do not align with the proper procedure for using a microscope.

When drawing observations in a microscopy experiment, it is important to provide a clear title, magnification information, and label important features using straight, uncrossed lines to ensure clarity and accuracy.

Cell differentiation is the process by which a cell changes its structure and functionality to perform a specific role within an organism. It is crucial for the development and maintenance of multicellular organisms.

Cells changing into different types of cells is a complex process involving the development of specific structures and functions necessary for the new cell type. This process is not random, chromosome-based, or completely understood.

Stem cells have the ability to differentiate into specialized cell types and are crucial for repairing and replacing damaged tissues in the body, such as skin and blood cells.

Undifferentiated cells are known as stem cells because they have the potential to develop into various types of cells in the body. Blood cells, nerve cells, and muscle cells are all differentiated cells that serve specific functions.

Sperm cells are specifically designed for reproduction and their primary role is to transport male genetic material to female genetic material for fertilization.

Nerve cells are specialized for rapid signaling and their main function is to transmit electrical signals around the body through axons and synapses.

Muscle cells are specifically adapted for contraction and generating force, as they play a vital role in movement and locomotion within the body. The incorrect answers provided do not align with the specialized function of muscle cells.

Root hair cells are specifically adapted to absorb water and minerals from the soil, not for producing oxygen, storing glucose, or conducting electrical signals. They lack chloroplasts because their main function does not involve photosynthesis.

The correct answer highlights the fact that animal cells are specialised and differentiate to carry out specific functions, contrary to the incorrect answers provided.

Plant cells are not all identical and do have specific functions through differentiation, which is a crucial process in cell development.

Living things are made up of cells, which are the basic structural and functional units of life.

Eukaryotic cells are characterized by the presence of a nucleus where genetic material is stored, along with other membrane-bound organelles. They can be found in organisms from various biological kingdoms, including plants, animals, fungi, and protists.

Eukaryotic cells are characterized by having a nucleus and membrane-bound organelles, which are present in plants, animals, fungi, and protists. Bacteria, Archaea, and Viruses are examples of prokaryotic cells or acellular particles, not eukaryotic cells.

Prokaryotic cells are characterized by the absence of a true nucleus where the genetic material is located. They have a single circular chromosome of DNA floating freely in the cytoplasm.
