Cells Flashcards
Central Vacuole
Stores water and may contain many substances, including ions, nutrients and waste
Mitochondria
An organelle that gets energy from organic compounds to make ATP the main energy of a cell.
Flagella
Long thread like structures that protrude from the cells surface and enable movement.
Resolution
Measure of clarity of an image , details of extremly small object
Cell Wall
Surrounding the cell membrane that provides STRUCTURE and SUPPORT. “ A plant stands tall bc it has a cell wall”
Cell membrane
encloses the cell and SEPERATES the cells interior
controls what ENTERS and LEAVES a cell
Cytoskeleton
Within the cytoplasm are the suspended in a system of microscopic fibers
Magnification
The quality of making an image appear 200 LARGER
than the objects size
Organelle
A structure that carries out a specific activity in the cell
Nucleus
An INTERNAL compartment that houses the cells DNA
Cilia
Short hairlike structures, Example- cilia on the lungs help sweep away mucus
Light microscope
light passes through one or more lenses to produce an enlarged image
Phospolipid
Is a lipid made of a phosphate group and 2 fatty acids
Chromosomes
When the cell is about to divide, however the DNA strands wind up into a more compact form and appear a ROD SHAPED structure.
Ribosomes
Cellular structures on which proteins are made
regulates cell activities
has RNA, enables cells to reproduce `
Golgi Apparatus
Set of flattend membrane bound sacs that serve as the packaging and distribution center of the cell.
Vesicle
Small membrane bound sac that transports substances in the cell.
lipid bilayer
phospholipid arranged in a double layer
POLAR
NON POLAR
POLAR
Chloroplast
organelles that use light energy to make carbohydrates
from carbon dioxide and water
lysosomes
Small spherical organelles that contain the cells digestive enzymes.
Golgi apparatus works with lysomes works with ER
Prokaryote
Smallest and simplest cells
lacks a nucleus and other internal compartments
Endoplasmic Reticulum (ER)
extensive system of internal membrane that move proteins and other substances through the cell.
Nuclear envelope
made up of 2 lipids bilayers that seperate the NUCLEUS from the CYTOPLASM.
Cell Theory
ABC
ALL living things are made of cells
BASIC units of structure and function in organism
CELLS rise from exsisting cells
