The function and location of all things in the cell
lysosome
contains digestive enzymes to help with cell digestion
Mitrochondria
called the powerhouse of the cell because it is involved in cellular respiration by converting glucose into ATP
nucleolus
controls all cell activities through the DNA located there
contains DNA and RNA
respocibnle for growth and reproduction
cytoplasm
the gel-like substance inside of cells
protects insides from damage
cytosol
Fluid portion of cytoplasm (75-95% water)
provides structural support
allows for transport of molecules
nucleoplasm
The jelly like fluid in the nucleus
protoplasm
the entire contents of the cell
organelles
structures in the cytoplasm that carry out specific functions
ribosomes
made up of RNA and proteins
Using RNA codes, amino acids are joined together to make proteins
endoplasmic reticulum
directly involved in the transportation of materials inside/within the cell, and creates lipids and proteins
Golgi apparatus
a protein and lipid storing, packaging and shipping machine
receives proteins and lipids from the endoplasmic reticulum
centrioles
The organelle within the cell that functions in cell division to separate chromatids
Inclusion
Chemical substances that are dissolved in the cytoplasm of a cell
nucleus
synthesis of ribosomal RNA
nuclear membrane
a two-layered structure that protects the nucleus, keeps DNA separate from the rest of the cell and manages what materials enter the nucleus
nuclear pore
channels for the selective transport of different substances and materials in and out of the nucleolus
cytoskeleton
internal scaffolding of protein fibres within the cytoplasm
made up of microtubules and micro filaments
microtubules
Hollow rods that keep organelles in place or move them around the cell.
microfilaments
They move materials around the cytoplasm or the whole cell.
cell membrane
the outer boundary of the cell
controls the movement of which substances can and cannot enter the cell
have four different proteins imbedded in the phospholipid bilayer, these are :
channel, carrier, receptor and recognition
channel protein
water filled pathway that allows smaller water- soluble substances to pass through the cell membrane
carrier protein
bind specific molecules to be transported on one side of the membrane.
used for larger substances or materials that cant easily diffuse though the cell membrane
receptor protein
binds with specific substances in the cells environment
transmitts signals inside the cell
recognition protein
have short carbohydrate tails which act as markers enabling cells to identify and interact with one another
