Organelles/Microscope Parts/Chapter 8

Does photosynthesis, only in plant cells

Chloroplast

Provide support, structure, and protection, only in plant cells

Cell Wall

regulates what enters and exits the cell

Cell Membrane

Number 1: transcribing RNA, producing ribosomes

Nucleolus

Moves substances in and out of the cell

Vesicle

gives room for communication inside the cell

Cytoplasm

give the cell structure support

Cytoskeleton

stores water and nutrients, enlarged in plant cell, many in animal cells

Vacuole

breaks down waste material

Lysosome

modified, stores, and packages proteins and lipids for transport

Golg Apparatus

rough: makes protiens, smooth: makes lipids

Endoplasmic Reticulum

converts the information from the RNA into a long amino acid chain

Ribosome

generates the cells supply of ATP

Mitochondria

#1

body

houses DNA, control center of the cell

Nucleus

Cell Theory #1

all living things have cells

Cell Theory #2

cells are the most basic life form

Cell Theory #3

new cells come from existing cells

Light Microscope

uses light to magnify an object

Transmission Electron Microscope

slided picture, 2D, object needs to be dead, vaccum

Scanning Electron Microscope

full pictyre, 3D, object needs to be dead, vaccum

Isotonic

equal amounts of concentration

Hypertonic

less concentration on the outside

Hypotonic

more concentration on the outside

facilitated diffusion

passive transport that moves substances down their concentration gradient

diffusion

the natural movement of molecules from an area of higher concentration to an area of lower concentration

active transport

the process of moving substances across a cell membrane against their concentration gradient, which requires energy, usually from ATP

osmsis

passive transport througba semi-permable membrane, typically in water
