Cell Biology
The 2 types of cell structures.
What are prokaryotic and eukaryotic cells?
This process converts carbon dioxide and water into glucose and oxygen using light energy
What is photosynthesis?
This structure acts as a boundary between a cell and its external environment.
What is the plasma membrane?
The passive movement of particles from high to low concentration.
What is diffusion?
This is the process of taking food into the body.
What is ingestion?
This cell lacks a nucleus.
What is prokaryotic?
The green pigment that absorbs light energy during photosynthesis.
What is chlorophyll?
The plasma membrane is mainly made of this double-layered structure.
What is a phospholipid bilayer?
The movement of water across a semi-permeable membrane.
What is osmosis?
The four main steps of digestion are ingestion, digestion, absorption, and this final step.
What is elimination?
This organelle contains genetic material.
What is the nucleus?
This organelle contains thylakoid membranes where light-dependent reactions occur.
What is the chloroplast?
These molecules have hydrophilic heads and hydrophobic tails.
What are phospholipids?
This type of transport uses protein channels but does not require energy.
What is facilitated diffusion?
This partially digested food leaves the stomach and enters the small intestine.
What is chyme?
Responsible for cellular respiration
What is the mitochondria?
This gas enters leaves through stomata to be used in photosynthesis.
What is carbon dioxide?
This model describes the plasma membrane as fluid and containing many embedded molecules.
What is the fluid mosaic model?
This transport process requires ATP and moves substances against a concentration gradient.
What is active transport?
This organ stores excess glucose as glycogen and produces bile.
What is the liver?
This organelle modifies and packages proteins in the cell.
What is the Golgi Apparatus?
Photosynthesis is classified as this type of metabolic reaction because it builds complex molecules.
What is an anabolic reaction?
This membrane component helps regulate fluidity at different temperatures.
What is cholesterol?
A solution where a cell gains water and may burst is described as this.
What is a hypotonic solution?
This organ produces digestive enzymes and also helps regulate blood sugar levels.
What is the pancreas?
