Microscopes
He is the scientist who looked at cork slices and made the term cells
Who is Robert Hooke?
They increase in size and complexity over time
What is growth and development?
This "mighty" organelle is the "powerhouse" of the cell, responsible for breaking down glucose to produce the energy (ATP) the cell needs to function
What are the mitochondria?
This is the main element found in all living things, which gives organic chemistry its name.
What is carbon?
This specific type of passive transport refers strictly to the movement of water molecules across a semi-permeable membrane from high to low concentration.
What is osmosis?
his Dutch scientist was the first to observe living cells (bacteria) using a simple microscope.
Who is Anton van Leeuwenhoek?
This creates new organisms, ensuring species survival.
What is reproduction?
Acting as the "post office," this organelle modifies, sorts, and packages proteins and other materials for transport out of the cell or to other locations within the cell.
What is the Golgi body (or Golgi apparatus)?
The main function of this organic compound, exemplified by enzymes and antibodies, is structure and function in the body.
What are proteins?
Unlike simple diffusion, this process uses specialized proteins to help large or polar molecules cross the membrane without requiring any cellular energy.
What is facilitated diffusion?
(1) all living organisms are made of one or more cells, (2) the cell is the basic unit of structure and function in all living things, and (3) all cells arise from pre-existing cells
what are the three principles of the cell theory?
The ability to maintain stable internal conditions
What is homeostasis?
This "command center" or "brain" of the cell contains the genetic material (DNA/chromosomes) and controls all cellular activities.
What is the nucleus?
Starch and cellulose are examples of this organic compound group, whose primary function is providing quick energy.
What are carbohydrates?
Cells utilize this form of active transport to "swallow" large particles by wrapping them in a portion of the cell membrane to form an internal vesicle.
What is endocytosis?
He invented the first compound microscope around 1595, significantly improving magnification and allowing for later discoveries.
who was Jensen?
This changes over generations to better suit their environment.
What is Adaptation/Evolution
This type of cell is simple, lacks a nucleus and other membrane-bound organelles, and includes bacteria.
What is a Prokaryote cell (or prokaryotic cell)?
Although inorganic, this vital compound is essential for life due to properties like cohesion, adhesion
What is water?
If a cell is placed in this type of solution, where the solute concentration is higher outside than inside, the cell will lose water and eventually shrink.
What is a hypertonic solution?
These two scientists concluded that all plants and all animals are made of cells.
Who are Schleiden and Schwann?
ex: (sunlight for plants, food for animals)
What is energy use?
Containing digestive enzymes, this "recycling center" or "Lysol cleaner" is responsible for breaking down waste materials, foreign substances, and old cell parts.
What are the lysosomes?
Fats, oils, and waxes are examples of this organic compound group, used by the body for long-term energy storage and insulation.
What are lipids?
The primary factor that determines whether a cell must use active transport instead of passive transport is if it needs to move molecules against this.
What is a concentration gradient?
