Cells Flashcards
Who studied corks and called them cells?
Robert Hooke
What are the three parts of the cell theory?
- all living things are made of cells
- cells are the basic unit of structures and functions in living things
- all cells are produced from other cells
What makes a cell prokaryotic?
single-celled and have no nucleus
What makes a cell eukaryotic?
made of multiple cells and have a nucleus
what organelles would only be found in plant cells?
chloroplasts and cell wall
The structure that regulates what enters and leaves the cell is called what?
cell membrane
What is the cell membrane composed of?
A phospholipid bilayer
In what organelle is a cell’s ATP produced?
mitochondria
Where are proteins made in the cell?
ribosomes
Which organelle breaks down worn out cell parts?
lysosomes
The packaging and distribution center of the cell is the?
golgi body/apparatus
The organelle associated with photosynthesis is?
chlorplasts
Would a larger cell or a smaller cell function better based on surface area and volume ratios?
Smaller
When liquid gets moved through a semipermeable membrane from an area of high concentration to an area of low concentration it is called what?
diffusion
What makes osmosis and diffusion different?
osmosis is only regarding water and solutes
A solution with a lot of particles in relation to liquid space is what?
a hypertonic solution
A solution with a lot more liquid than particles is what?
a hypotonic solution
A solution with balanced particles and liquid is what?
an isotonic solution
When proteins or other particles pass through the membrane by way of a protein channel it is what?
facilitated diffusion
Simple, osmosis, facilitated diffusion (transport not needing energy) are what?
forms of passive transport
What are two forms of active transport?
Endocytosis and Exocytosis (transport requiring energy)
Endocytosis and Exocytosis do what?
Transport molecules that are too large to move across a cell membrane through the cell membrane
