Microscopes
The smallest unit of life.
What is a cell
A thin, flexible barrier that surrounds a cell.
What is the cell membrane?
What is passive transport?
Cells that differ in function and structure.
What are specialized cells?
Storage sacs contained in both plant and animal cells.
What are vacuoles?
The area under the stage that limits how much light is passed through from the light source.
What is the diaphragm?
Rod-shaped organelle structures within a cell that convert energy stored in food.
What are mitochondrion?
A passive transport system where molecules move from an area of higher concentration to lower concentration
What is diffusion?
Different types of tissue that function together.
What is an organ?
What are chloroplasts?
The total magnification of an image using one 10x lens and one 40x lens.
What is 400x?
This cellular structure is rigid and made of cellulose or chitin.
What is the cell wall?
Explain the difference between diffusion and osmosis.
Diffusion is when molecules move from a higher to lower concentration. Osmosis is a type of diffusion where water molecules move across a membrane to an area where there are less water molecules.
The function of red blood cells.
What is delivering oxygen to cells throughout the body?
Acts like a receiving, packaging, and shipping facility within the cell; both animals and plants have this organelle.
What is the Golgi apparatus?
A type of microscope with more than one lens.
What is a compound microscope?
A jelly-like substance filling the interior (inside) of the cell.
What is cytoplasm?
Pinching off a vacuole within a cell to move its contents outside of the cell.
What is exocytosis?
What is structure?
An organelle that processes substances, such as proteins and fats.
What is the endoplasmic reticulum?
The relationship between resolution and being able to better see (clarity) structure details in an image.
What is a direct (positive) relationship?
"As one increases, the other increases"
Name the organelle that is the site of protein synthesis.
What are ribosomes?
The definition of "selectively permeable.""
What is it called when some substances can cross a cell membrane but others cannot?
The levels of a multicellular organism's organism, from simplest to most complex.
What are molecules, cells, tissues, organs, organ systems, and an organism?
Strands of genetic material that contain instructions for cell function.
What is chromatin?
