Cell Discovery
These observed by Robert Hooke in cork with his microscope and called the tiny boxes this.
Cells
The security guard of the cell made of phospholipids and proteins.
What is the cell membrane?
This gel-like fluid fills the space inside a cell. It holds all of the organelles in place.
What is cytoplasm?
This organelle provides the cell with the ATP it needs to perform its functions and activities.
What is the mitochondria?
This cell process is the result of oxygen and carbon dioxide moving across the cell from an area of high to low concentration.
What is diffusion?
This is the concept that Eukaryotic cells came about by consuming other cells.
What is endosymbiont theory?
The function of the vacuole.
What is the storage center for waste, water, and food?
The most complex level of organization in living things.
What is an organism?
This type of cell transport takes place without the use of energy.
What is passive transport?
What is Cell Theory?
This has ribosomes attached and plays an important part in finalizing proteins.
What is the rough ER?
A group of cells working together make up this level of organization.
What is a tissue?
This cell process happens when water diffuses across the cell membrane.
What is osmosis?
This cell type has NO nucleus or other membrane bound organelles. Bacteria are the only example of this cell type.
What is a prokaryote?
What is the green organelle in a plant cell where photosynthesis takes place?
This organelle is a series of interconnected passageways or roadways. It is a transporter of the cell.
What is the cytoskeleton?
These are made by the nucleolus and their function is to make PROTEINS. They are free-floating or may be found attached to the ER.
What are ribosomes?
A solution that has MORE dissolve salts than the cell is considered _______ in comparison to the cell and will shrink the cell.
What is hypertonic?
list each statement of the cell theory... list the 3 statements
1. All living things are made of cells. 2. Cells are the basic unit of life. 3. Cells only come from pre-existing cells.
The organelle in a plant cell that helps provide rigidity and structure located on the outside of the cell.
What is the cell wall?
This organelle digests worn out cell parts and also plays a role to defend the cell from infection. It is sometimes referred to as the clean up crew of the cell.
What is a lysosome?
The three differences between plant and animal cells are:
What are 1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Animal cells have centrioles or lysosomes? (or plants have large central vacuoles)
This process removes waste from the cell.
What is exocytosis?
