Cells Flashcards
What type of cell has no nucleus
Prokaryotic cells
What type of cell has a nucleus
Eukaryotic cell
Controls what enters and leaves the cell
Cell membrane
Watery material that makes up most of the cell
Cytoplasm
Information center for cell, contains chromosomes and nucleolus
Nucleus
Site of ribosome production
Nucleolus
Contains DNA
Chromosomes
Site of cellular respiration. “Powerhouse of the cell”
Mitochondria
Assists in building proteins
Ribosomes
Stroage bins for nutrients and waste
Vacuole
Tubular passageways that transport proteins
Endoplasmic reticulum
Produces lysosme membranes. Also packages proteins and carbohydrates. (Looks like a stack of pancakes)
Gogli body
Contains enzymes that break down proteins. (animal cells only)
Lysosomes
Plays a part in cell division
Centrioles
An outer shell that protects and supports plant cells.(plant cells only)
Cell wall
Contains chlorophyll, can change light energy into chemical energy (food) (Plant cellsonly)
Chloroplasts
What does the lipid bilayer consist of
Proteins, carbohydrates and lipids
Has a hydrophobic head and a hydrophillic tail
Lipid bilayer
moves from an area of high concentration to low concentration
Diffusion
the ability To move across a membrane
Permibility
The movement of water through or across a selectivly permeable membrane
Osmosis
Concentration of solutes is the SAME inside and outside the cells
Isotonic
Solution has a HIGHER solute concentration than the cell
Hypertonic
Solution has a LOWER solute concentration than the cell
Hypotonic
Typeof transport that requires energy
Active transport
Type of transprt that does not reqire energy
Passive transport
What does ATP stand for
Adenosne triphosphate
What is ATP composed of
Adenosine, ribose and 3 phosophate groups
