Cell Wall
|
The cell wall is a rigid layer of nonliving material that surrounds the cells of plants and some other organisms. The cells of the animals, in contrast, don't have cell walls. A plant's cell wall is mostly of a strong material calls cellulose. Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
rigid layer of non-living material surrounding the cell. found in plant cells and in bacteria |
|
|
Cell Membrane
|
All cells have cell membranes. In cells with cell walls, the cell membrane is located just inside the cell wall. In other cells, the cell membrane forms the outside boundary that separates the cell from its environment.
the cell membrane controls what substances come into and out of a cell. Barrier between cell and its enviroment |
|
|
Nuclear Envelope
|
the nuclear envelope protects the nucleus. materials pass in and out of the nucleus through pores in the nuclear envelope. So aim for that pore just ahead and carefully glide into the nucleus.
|
|
|
Cytoplasm
|
gel - like fluid
suspends the organelle dissolves important chemicals needed for life. |
|
|
Chromatin
|
(DNA and histone proteins)
contains genetic material contains instructions for running the cell instructions = genes copies are called RNA |
|
|
Ribosomes
|
found on endoplasmic reticulum
make proteins read RNA instructions and use them to make proteins |
|
|
nucleus
|
directs cells activities including reproduction
|
|
|
nuclear
|
protects chromatin (DNA)
materials pass in and out through the pores |
|
|
nucleolus
|
produces ribosomes
|
|
|
organelle
|
tiny structures that has a particular function
|

|
|
|
mitochondria
|
mitochondrion - one
mitochondria - more than one change food into energy. (converts energy in food into energy that the cell can use requires oxygen it is made of two membranes |
|
|
endoplasmic reticulum
|
rougher ER --> rER - transports proteins from ribosomes to the Golgi body.
rER is covered in ribsosmes. smooth Er --> sER - produces and transports facts thoughtout the cell |
|
|
vacuoles
|
stores food, waste and water
animal cells have many samll ones, or none at all plant cells have one LARGE one. |
|
|
Golgi body
|
receives proteins from rER
sorts them packages them sends them to other parts of the cell - outside the cells - membrane - lysosome |
|
|
lysosome
|
they contain digestive enzymes which break down old, worn out organelles and big food particles.
|
|
|
lysosome
|
they contain digestive enzymes which break down old, worn out organelles and big food particles.
|
|
|
chloroplast
|
site of photosynthesis, which ios maki9ng food from sunlight energy, and CO2. (Oxygen is a waste product.
ENERGY --> chloroplast --> food and O2 --> mitochondira --> ENERGY |
