What is an Animal Cell?
100
This type of microscope uses light and lenses to magnify specimens and is commonly used in school laboratories.
What is a light microscope?
100
This cellular model describes how membrane components can move laterally within a phospholipid bilayer, explaining membrane flexibility and dynamic interactions.
What is the Fluid Mosaic Model?
100
This specific transport mechanism allows large or charged molecules to cross the cell membrane against their concentration gradient, requiring cellular energy.
What is active transport?
100
The hydrolysis of ATP releases energy by breaking these high-energy bonds, which are crucial for driving many cellular processes.
What are the phosphate bonds in ATP?
200
This cellular powerhouse generates most of the cell's ATP through respiration.
What are mitochondria?
200
These microscopic technologies allow scientists to examine cellular structures at nanoscale resolutions, revealing intricate details impossible with traditional light microscopy.
What are electron microscopes?
200
These polar regions of phospholipids interact readily with water molecules, creating the outer surfaces of the cell membrane.
What are the hydrophilic phosphate heads?
200
In diffusion, particles move from an area of ___ concentration to an area of ___ concentration.
What is high to low?
200
The overall equation for photosynthesis involves the conversion of carbon dioxide and water into glucose and this byproduct.
What is Oxygen?
300
This double-membraned organelle contains its own DNA and is responsible for photosynthesis in plant cells.
What are chloroplasts?
300
Label lines in biological diagrams should never have these at the ends.
What are arrows?
300
This molecule is scattered among phospholipids and helps to maintain membrane fluidity and stability.
What is cholesterol?
300
This type of passive transport uses protein channels to help large or charged particles cross the membrane.
What is facilitated diffusion?
300
The process of photosynthesis has two main stages: the light-dependent reactions and this stage, which does not require light.
What are light-independent reactions (The Calvin Cycle)?
400
This organelle contains digestive enzymes and breaks down cellular waste, damaged organelles, and foreign materials.
What are lysosomes?
400
In biological diagrams, this should be included if the drawing is not life-sized, so the viewer understands the size of the structures.
What is a scale?
400
These specialized membrane proteins span the entire phospholipid bilayer and can function as channels, carriers, or receptors for cellular communication.
What are transmembrane proteins?
400
This type of active transport involves the cell engulfing large particles or liquids by wrapping its membrane around them.
What is endocytosis?
400
This is the primary pigment responsible for absorbing light energy during photosynthesis.
What is Chlorophyll?
500
This organelle is a network of membranes without ribosomes, playing a key role in synthesising lipids and detoxifying harmful substances in the cell.
What is the smooth endoplasmic reticulum?
500
This part of a microscope adjusts the amount of light that reaches the specimen.
What is the diaphragm?
500
These membrane proteins are involved in cell recognition and often have carbohydrate chains attached.
What are glycoproteins?
500
Cells placed in a hypertonic solution will do this as water moves.
What is shrink/ shrivel?
500
This stage of cellular respiration produces the most ATP and occurs in the inner membrane of the mitochondria.
What is the Electron Transport Chain?
