Definition
1. All living things are made of cells
2. cells are the most basic unit of life
3. cells come from existing cells |

Term
| what are the main structures that both plant and animal cells contain? |
|
Definition
| cell membrane, cytoplasm, nucleus, nucleolus, ribosomes, endoplasmic reticulum, golgi complex, mitochondrion, lysosomes |
|
|
Term
| What are the structures that plant cells have that animal cells do not? |
|
Definition
| cell wall, chloroplast, central vacuole |
|
|
Term
| what is the celll membrane? |
|
Definition
aka plasma membrane
it is a thin fexible barrier around the cell that regulates what goes in and out of the cell. It is primarily made up of phospholipid bilayer |
|
|
Term
|
Definition
| it is the fluid and all organelles ( except nucleus) inside of the cell, the fluid has filaments to provide structure and support for cell and organelles |
|
|
Term
| What is the fluid part of cytoplasm called? |
|
Definition
|
|
Term
|
Definition
| it is the control center of the cell. it contains DNA which controls cells activities by directing which protiens to assemble. |
|
|
Term
|
Definition
| it is found in the nucleus. creates ribosomes by combining protien and RNA |
|
|
Term
|
Definition
they are used for protien synthesis.
they are attached to ER or free floating in cytosol |
|
|
Term
| what is the endoplasmic reticulum? ER... |
|
Definition
there are two kinds: smooth and rough
smooth: no ribosomes, used for lipid synthesis
rough: ribosomes on surface, used to modify protiens and make membrane.
They are a system of interconnected membranes that transport protiens and lipids |
|
|
Term
| what is the golgi complex? |
|
Definition
aka Golgi appartatus, golgi body, etc
they are a stack of flattened membranes that recieve products from the ER. It modifies, packages, and transports materials out of the cell. |
|
|
Term
| what are mitochondrion (sing)/ mitochondria (pl)? |
|
Definition
| they convert food energy (carbohydrates and lipids) to ATP |
|
|
Term
|
Definition
they are filed with digestive enzymes. they break down materials such as biomolecules, wastes, cell parts, etc for use by cells.
they are present in animals. rarely found in plants |
|
|
Term
|
Definition
ONLY IN PLANTS
found outside of the cell membrane
it protects and supports the cell |
|
|
Term
|
Definition
ONLY IN PLANTS
it is an organelle containing chlorophyll pigment
it is the site of photosynthesis.
it makes food. |
|
|
Term
| what is a central vacuole? |
|
Definition
ONLY IN PLANTS
it is a large compartment that stores materials such as water, nutrients, and wastes |
