The smallest unit capable of performing life functions are...
Homeostasis
Cells
Rough ER
Lysosomes
All plants are made from .
The Cell Theory states....
All living things are made up of at least one cell.
Robert Hooke discovered the first cell.
Cells are the smallest unit capable of performing life functions.
All cells come from preexisting cells through cell division.
Unicellular means...
An organism has more than once cell.
An organism has one cell only.
Prokaryotes have a nucleus and organelles.
Multicellular organisms have more than one cell.
Eukaryotes have a nucleus and organelles.
Organelles have and are surrounded by a membrane.
The cell membrane...
Protects and supports the cell
Feeds and nourishes the cell
Regulates the transport of materials in and out of the cell
Controls the cell
Lipid Bilayer is a of that make up the cell membrane.
The cell membrane is mad of many different parts that move freely.
: Some substances can pass through the cell membrane. But
Permeate means "porous" or "pass through"
Passive transport is...
the movement of substances into/out of cell without using energy.
the movement of substances only in a cell using cell energy.
Passive transport goes from high to low concentration low to high concentration none to many substances working to not working organelles.( high to low concentration, low to high concentration, none to many substances, working to not working organelles. ).
The types of passive transport:
Simple Diffusion
Facilitated Diffusion
Osmosis
In simple diffusion, molecules move from high to low low to high water to solute( high to low, low to high, water to solute ) concentration until it reaches equilibrium diffusion greater solute than solvent( equilibrium, diffusion, greater solute than solvent ).
In facilitated diffusion, some molecules can't diffuse through the membrane and require special protein channels to move through.
Osmosis is the through special channels called .
