Cellular Structure
This theory states:
1. all organisms are composed of one or more cells
2. cells are the basic unit of life
3. all cells come from pre-existing cells
What is the cell theory?
This organelle is not found in animal cells and is the site of photosynthesis.
What are chloroplasts?
What process moves molecules from high concentration to low concentration?
What is diffusion?
This molecule is a product of cellular respiration which occurs in the mitochondria and is used for cell energy.
What is ATP?
The term is used to describe a solution that has more solutes.
What is hypertonic?
These cells have a cell membrane, cytoplasm, ribosomes and genetic material (DNA & RNA)?
What are ALL cells?
These sacs contain digestive enzymes and along with centrioles are only found in animal cells.
What are lysosomes?
This term best describes how the cell membrane functions to regulate what enters and leaves the cell.
What is semi-permeable?
What is against the concentration gradient, or from low concentration to high concentration?
When placed in this solution water enters the cell and it swells.
What is hypotonic?
These cells do not have a nucleus or membrane-bound organelles.
What are prokaryotic cells?
This membranous organelle make proteins and is studded with ribosomes.
What is the endoplasmic reticulum?
The diffusion of water across a semi-permeable membrane.
What is osmosis?
This transport moves large materials into and out of the cell.
What is bulk transport?
What is the central vacuole?
This exterior support is found in plant cells and many prokaryotes.
What is the cell wall?
This organelle modifies, sorts and ships proteins and lipids using vesicles.
What is the Golgi apparatus?
This macromolecule aids the diffusion of large, polar molecules across the plasma membrane.
What are transport proteins?
This process uses vesicles to move materials into the cell.
What is endocytosis?
This whip-like structure helps cells move in aqueous environments.
What is the flagellum or flagella?
These cells are more complex and store DNA in the nucleus.
What are eukaryotic cells?
This organelle makes lipids, stores Calcium, detoxifies toxins and metabolizes carbohydrates.
What is the smooth endoplasmic reticulum?
These molecules can easily pass through the cell membrane.
What are small, nonpolar molecules?
This processes forms vesicles to move materials out of the cell.
What is exocytosis?
These structures are the site of protein synthesis and are found in all cells.
What are ribosomes?
