Cell Parts
What is the cell membrane?
A thin, flexible layer that surrounds the cell, controlling what goes in and out, like a screen door
What is the mitochondria?
The mitochondria are the powerhouse, producing ATP from nutrients, fueling the cell.
This process allows a cell to use oxygen and nutrients to release usable energy.
cellular respiration
Some Animal Cells do have Thin Cell walls that Protect the Cell
False
These small membrane-bound sacs transport materials around the cell.
Transport Vesicles
What is cytoplasm?
Cytoplasm is the jelly-like substance that holds all the organelles.
What is Rough ER?
The Rough ER is where proteins are created, folded and quality control
This process uses energy to move substances against their concentration gradient.
Active transport
Animal Cells and plant cells have mitochondrias
True
Unlike plant cells, animal cells usually obtain energy by breaking down nutrients rather than making their own food through this process.
photosynthesis
What are Ribosomes?
Ribosomes make proteins by reading genetic material from RNA
What is the Golgi Apparatus?
The Golgi Apparatus modifies, packages, and sorts proteins and lipids from the Endoplasmic reticulum.
This process moves water across a selectively permeable membrane.
Osmosis
Animal Cells have a recycling system
True, Lysosomes break down waste into useful material
All animal cells are exactly the same shape
False
What is the Nucleus?
Membrane-enclosed command center that holds all the DNA and directs cellular activities
What is the Smooth ER
The smooth ER Makes lipids and steroids hormones without ribosomes attached to them.
This process allows a cell to make an RNA copy of instructions from DNA.
Animal cells have Central Vacuoles that store stuff
False they have small temperary Vacuoles.
This selectively permeable structure helps an animal cell maintain a stable internal environment.
cell membrane
What is the Cytoskeleton?
A network of protein fibers that gives the cell shape, providing mechanical support.
What are lysosomes?
They break down worn-out cell parts, large molecules, and invading bacteria or viruses. They recycle them into nutrients.
This process uses mRNA instructions to build a protein at a ribosome.
translation
Some Ribosomes are held tight within the cytoplasm making them bound
false they are either free-floating or attached to the ER
These are the basic building blocks of all animals.
