Organelles
What is an organelle in the cytoplasm of eukaryotic cells?
Lysosome
What is the difference between Eukaryotes and prokaryotes?
Prokaryotes have DNA and the size is usually stronger, whereas the eukaryotes are within the membrane and usually larger.
Is a cell membrane living?
Plasma membrane is a living membrane.
Define isotonic
When the concentration of 2 solutions is the same
Whats the difference between active and passive transport?
Active transport requires energy for the movement of molecules, and passive transport does not require energy for the movement of molecules.
What cell organelle consists of RNA?
Ribosomes
Strong supporting layer around the cell membrane in some cells is...
Cell wall
What does a cell membrane maintain?
It maintains homeostasis.
What's the difference between hypertonic and hypotonic
Hypotonic is having lower osmotic power typically body fluid. Hypertonic is having a higher osmotic pressure than a particular fluid.
Define osmosis.
The diffusion of water across a semi-permeable membrane
What type of cell organelle coverts chemical energy stored in food into compounds that are more convenient for the cell to use?
Mitochondria
What internal membrane is found in eukaryotic cells?
Endoplasmic reticulum
Where is the cell membrane located?
What makes a solution hypotonic?
When it has a lower solute concentration
What is movement of large or charged molecules via membrane proteins?
Facilitated diffusion
What organelle is found in cells of plants and some other organisms?
Chloroplasts
What's similar between endocytosis and exocytosis?
They both transport materials across the cell membrane by forming vesicle pores
What cell has no cell membrane?
What makes something more hypertonic?
When its solute concentration is higher than that inside the cell.
What transport uses energy?
Active transport
What are the three most important organelles?
Ribosomes, Mitochondria, Nuclei
Cytoskeleton is_________.
A network of protein filaments in a eukaryotic cell that gives the cell its shape
What cells contain cell membranes?
Does hyper tonic shrink or grow?
It causes the cell to shrink.
What are 4 major transports?
Simple diffusion, facilitated diffusion, primary active transport and secondary active transport.
