Prefix-Suffix pt 1
1. Glycogen is stored in the ______ and ______.
2. All chemical reactions that take place in the body are called ______________.
I. Three Main Parts of the Cell:
barrier that separates and protects the cell from its environment. It is selectively permeable (it allows only certain materials in and out of the cell).
jelly-like fluid that fills the cell.
It contains water, food, building materials, and organelles.
(cyto- cell, -plasm – fluid)
controls all activities of the cell.
There are two main categories of cells, which are divided by the presence or absence of a nucleus.
Nucleolus: where ribosomes are made
Chromatin: individual, stringy strands of DNA
porous membrane that surrounds and protects the DNA
Ribosomesare small, round organelles that make proteins and deposit them inside the Rough ER. “Protein Factories”
Rough ER- are the tunnels
Ribosomes are the dots
Rough Endoplasmic Reticulum (ER)is a system of membrane tunnels with ribosomes attached to its outer walls.
Golgi Bodies or Golgi Apparatussorts, packages and transports proteins“Protein Mail Room”
“lyso- to break, -some – body”
Lysosomes- sacs of digestive enzymes that break down and get rid of worn-out organelles within the cell.
Where chemical energy in food is transformed into a more usable form for the cell to use.
“cyto- cell, -skeleton – support structure”
Supports the cell’s structure. Some help the cell move in its environment.
Examples: cilia – short, hair-like structures
flagella – long, tail-like structure
supports and protects the plant cell and is found outside of the plasma membrane.
It is made of cellulose, which is the main component in wood and paper.
Plants have one large vacuole that helps the cell keep its shape by pumping it up with water.
(Vacuoles are also found in animal cells, but are much smaller.)
Are responsible for the process of photosynthesis which converts light energy into chemical energy stored in glucose.
