Cell Discovery
This man observed cork with his microscope and called the tiny boxes 'cells'
Who was Robert Hooke
This property of the cell membrane allows some things to enter/leave the cell, and blocks other things from doing so.
What is selective permeability?
This fills the space inside a cell. It is a jelly-like fluid and is composed of water.
What is cytoplasm?
This organelle provides the cell with the energy it needs to perform its functions and activities. The powerhouse of the cell.
What is the mitochondria?
This type of passive transport occurs when particles of a substance move from high concentration (where there are many particles) to low concentration (where there are few particles).
What is diffusion?
This cell type contains a nucleus and organelles (such as mitochondria).
What are eukaryotic cells?
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
The type of passive transport occurs when a transport protein is required to move large molecules from high to low concentration.
What is facilitated diffusion?
What is the tool discovered by Leeuwenhoek that scientist use to research small things such as cells and microorganisms?
What are microscopes?
What is the structure of a cell membrane?
Phospholipid Bilayer
This organelle arranges, packages, and delivers proteins in or out of the cell.
What is the Golgi apparatus
This occurs when water diffuses into a cell.
What is osmosis?
Match the scientist to the quote:
"All plants are made out of cells" Schwann
"All animals are made out of cells" Virchow
"All cells come from other living cells" Schleiden
Matthias Schleiden
Theodor Schwann
Rudolf Virchow
This organelle is a series of interconnected passageways. Proteins and lipids are made here and transported. There are two varieties 'Smooth' and 'Rough'.
What is the endoplasmic reticulum?
These organelles are free-floating or may be found attached to the ER, but they are used to make proteins.
What are ribosomes?
What is the difference between pinocytosis and phagocytosis?
Pino - cell drinking
Phago- cell eating
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 other cells.
Why is the cell membrane important for homeostasis?
It regulates temperature, pH, water, and glucose
It makes food from the sun's energy
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Plant cells have a large central vacuole.
The sodium/potassium pump requires energy to pump against the concentration gradient (low to high concentration). This is an example of this type of transport.
What is active transport?
