Cell Organelles by Me

Terms in this set (14)

Fluid material of the cell that contains organelles

•A cell structure that controls which substances can enter or leave the cell
•It's semi-permeable

Rapid plasm structure providing support and protection

Bundles of microtubules play a role in organizing the movement of chromosomes during cell division

•Membranes that contain chlorophyll
•Absorbs light energy and conducts photosynthesis
•water + carbon dioxide + light energy —— glucose + oxygen

Endoplasmic Reticulum

•Network of branching tubes and pockets
•Transports substances throughout the cell

Golgi Apparatus

Modifies, sorts, and packages proteins, sugars, and enzymes for storage or transport out of the cell

Contains digestive enzymes that can break down substances brought into the cell

•Powerhouse of the cell
•Conducts cellular respiration
glucose + oxygen—— carbon dioxide + useable energy

•Control center of the cell
•Chromosomes contain genetic information DNA
•Controls cell activities

Nuclear Membrane

Controls what goes in and out of the nucleus

Produces ribosomes

Site of protein building

Animal— small, aid in breakdown of cell substances
Plant— large, stores water, nutrients, wastes and digestive enzymes

Verified answer

physics

The normalized ground-state wavefunction for the electron in the hydrogen atom is $\psi(r, \theta, \phi)=\frac{1}{\sqrt{\pi}}\left(\frac{1}{a_{0}}\right)^{3 / 2} e^{-r / a_{0}}$ where r is the radial coordinate of the electron and $a_{0}$ is the Bohr radius. (a) Sketch the wavefunction versus r. (b) Show that the probability of finding the electron between r and r = dr is given by $|\psi(r)|^{2} 4 \pi r^{2} d r$. (c) Sketch the probability versus r and from your sketch find the radius at which the electron is most likely to be found. (d) Show that the wavefunction as given is normalized. (e) Find the probability of locating the electron between $r_{1}=a_{0} / 2$ and $r_{2}=3 a_{0} / 2$.
