Acting as the cell's "post office," this organelle modifies, sorts, and packages proteins for delivery to their destinations.
What is the Golgi apparatus?
Cells lacking a nucleus and membrane-bound organelles are classified under this domain.
What are prokaryotic cells?
Common in biology labs, this microscope uses visible light to magnify images of small specimens, including living cells.
What is a light microscope?
Living organisms maintain a stable internal environment despite external changes through this essential process.
What is homeostasis?
He coined the term "cell" after observing tiny compartments in cork, comparing them to monastery rooms.
Who is Robert Hooke?
Known as the "cleanup crew," these organelles contain enzymes to digest and recycle worn-out cell parts and macromolecules.
What are lysosomes?
This organelle is the universal site of protein synthesis found in all cells, big or small.
What are ribosomes?
This microscopy technique scans the specimen's surface with electrons to create detailed three-dimensional images.
What is scanning electron microscopy (SEM)?
This life process enables organisms to produce new individuals, ensuring the survival of their species.
What is reproduction?
This pioneer was the first to observe living microorganisms, calling them "animalcules," using his handcrafted microscopes.
Who is Anton van Leeuwenhoek?
This double-membrane-bound organelle houses the cell's genetic material and coordinates activities like growth and reproduction.
What is the nucleus?
Name two organelles present in eukaryotic cells but absent in prokaryotic cells, highlighting a key difference between them.
What are the nucleus and mitochondria (accept any two membrane-bound organelles like endoplasmic reticulum, Golgi apparatus, chloroplasts in plants)?
While examining cells under a microscope, you notice a double-membraned organelle with its own DNA, crucial for energy production in eukaryotic cells.
What is the mitochondrion?
The totality of an organism's chemical reactions, managing energy resources, is known by this term.
What is metabolism?
Name one of the two scientists who established that all plants and animals are made up of cells, forming a foundation of cell theory.
Who are Matthias Schleiden or Theodor Schwann?
Composed of microtubules and microfilaments, this network provides structural support and facilitates cell movement and division.
What is the cytoskeleton?
Bonus Question - Prokaryotic cells replicate rapidly through this simple asexual reproduction method, unlike the complex mitosis in eukaryotes.
What is binary fission
To observe the intricate internal structures of thinly sliced specimens at high resolution, scientists use this electron microscope.
What is transmission electron microscopy (TEM)?
Organisms detect and respond to these environmental triggers, which can include light, temperature, and chemical signals.
What are stimuli?
He asserted that all cells arise from pre-existing cells, completing the classical cell theory and advancing medical science.
Who is Rudolf Virchow?
These organelles, once free-living prokaryotes, generate ATP through cellular respiration and contain their own DNA and ribosomes.
What are mitochondria?
Daily Double - These small, circular DNA molecules in prokaryotes replicate independently and often carry genes for antibiotic resistance.
What are plasmids?
In plant cells viewed under a microscope, you observe large, green organelles responsible for capturing light energy and converting it into chemical energy through photosynthesis.
What are chloroplasts?
Over generations, populations change through this process, leading to the diversity of life observed today.
What is evolution?
Daily Double - This theory explains how eukaryotic cells evolved when one prokaryotic organism began living inside another as a symbiont.
What is the endosymbiotic theory?
