Cell Discovery
This man observed cork with his microscope and called the tiny boxes 'cells'
ROBERT HOOKE
This property allows some things to enter/leave the cell, and blocks other things from doing so.
SELECTIVE PERMEABILITY
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
CYTOPLASM
This organelle provides the cell with the ATP it needs to perform its functions and activities.
MITOCHONDRIA
Why do plant cells have a rigid cell wall?
To provide structural support and maintain the plant's shape.
This cell type contains a nucleus and organelles (such as mitochondria).
EUKARYOTIC CELLS
The part of the phospholipid that 'loves' water
HYDROPHILIC HEAD
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
NUCLEUS
These structures are used for cell movement. The first is long and there are usually very few of them. The second are short and there are usually many of them.
FLAGELLA and CILIA
Why are chloroplasts found in plant cells?
for PHOTOSYNTHESIS
Who proposed that all cells arise from pre-existing cells?
RUDOLF VIRCHOW
What are the 3 biomolecules/organic compounds found in phospholipid bilayers?
CHOLESTEROL, CARBOHYDRATES, PROTEINS
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
GOLGI APPARATUS
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
LYSOSOME
What organisms are unicellular?
BACTERIA
This cell type has no nucleus or other organelles. Bacteria are the only example of this cell type.
PROKARYOTIC CELL
What are the biomolecules made of carbon, hydrogen, and oxygen? They are the body's main source of energy.
CARBOHYDRATES
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
ENDOPLASMIC RETICULUM
These are made by the nucleolus and their function is to follow DNA instructions to make stuff. They are free-floating or may be found attached to the ER.
RIBOSOMES
FACT or BLUFF: Bacteria perform all life functions in one cell; humans have many specialized cells.
FACT
List the 3 statements of the cell theory
1. All living things are made of cells. 2. Cells are the basic unit of life. 3. Cells only come from other cells.
These lipids are located within the phospholipid bilayer, and they function to stablize the cell membrane
CHOLESTEROL
This organelle is found only in animal cells. It is made of microtubules and is thought to play a role in cell division.
CENTRIOLES
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Animal cells have centrioles.
A student observes a cell under a microscope and notices a large central vacuole and green pigments. What kind of multicellular cell is the specimen?
PLANT CELL
