Cell Discovery
The security guard of the cell.
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?
Anton Leeuwenhoek scraped his teeth and the side of the pond to discover two things.
What are bacteria and protists?
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?
This scientist studied several animals and determined that they were all made of cells.
Who is Theodor Schwann?
This type of ER has ribosomes attached.
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 endoplasmic reticulum?
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?
The 3 reactants needed for photosynthesis.
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.
I quit my job in the plant cell and now it no longer has its rigid box like shape.
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?
