Cell Theory & Microscopes
The scientific theory states that all living things are made of cells
What is Cell Theory?
The powerhouse of the cell
what is mitochondria?
transport that moves particles from high concentration to low concentration without energy
what is passive transport
plant tissue that carries water from roots to leaves
what is xylem?
Cell → Tissue → Organ System
what is multicellular organization?
multiplication of the ocular lens by the objective lens
what is total magnification
organelle that packages and ships materials within the cel
what is the golgi apparatus?
movement of water from high to low concentrations
what is osmosis?
plant tissue that carries sugars to other parts of the plant
what is phloem?
Matter and energy enter and leave the cell.
what is an open system?
makes structures easier to observe under a microscope
what is staining?
the organelle that contains digestive enzymes that break down waste
what is the lysosome?
movement of particles against the concentration gradient, needs energy.
what is active transport
plant tissue that has high surface area to volume ratio.
what is root hairs?
This is one benefit of multicellular organisms having specialized cells.
what is efficient division of labour?
previous assumption, where Microorganisms come from non-living matter
What is spontaneous generation
one organelle builds proteins, and the other helps transport/process the proteins
what is ribosome and rough ER?
use of membrane proteins, does not require energy and moves particles from high to low concentration gradient
what is facilitated diffusion
part of leaf structure that is tightly packed with many chloroplasts for photosynthesis
what is palisade tissue?
This ratio limits how large a cell can become.
What is the surface area to volume ratio?
microscopic technique, where image is enlarged, clarity/detail is enhanced, and difference between structures is amplified so it stands out.
what is magnification, resolution, and contrast?
what is chloroplast and mitochondria?
cell is placed in a solution and shrinks.
what is hypertonicity?
force that keeps water molecules together, where another force helps water stick to xylem walls.
what is cohesion and adhesion?
These cells exchange materials faster because they have a higher surface area to volume ratio.
What are small cells?
