What is a Prokaryote?

A LIVING cell that:  NO Nucleus or membrane bound organelles. “Pro” = “No Nucleus”  DOES have Cell Membrane, DNA (circular type), Ribosomes, Cytoplasm, and Cilia and/or Flagella Bacteria

What is a Eukaryote? All Plant, Animal, Fungi, Protista Cells!!!  Have NUCLEUS and Membrane bound organelles “Eu” = “Yes Nucleus”

What MUST all cells (Eukaryotes & Prokaryotes) have? 4 Things: DNA Cytoplasm Cell Membrane Ribosomes

What 3 things does a Plant cell have that an Animal cell does NOT have? Cell Wall Chloroplasts Large Vacuole

List the 3 parts of the Cell Theory Cells are the basic unit of life Cells come from existing cells All living things are made of 1 or more cells

Who invented the microscope and saw the first living cells in pond water and called them “wee beasties?” Leeuwenhoek

Who saw cork and named the chambers “Cells”? Hooke Sounds like cork!

What did Schwann say? What did Schleiden say? Schwann claimed that all animals are made of cells. Think: Schwann sounds like Swan the animal Schleiden claimed that all plants are made of cells. Think: Schlidin’ down the vine and vines are plants

Who claimed that all cells must come from existing cells (reproduce)? Way to Remember: Cows come from cows Cells come from cells

Who did this experiment and did he believe in biogenesis or abiogenesis? Redi - Biogenesis

Who did this experiment and did he believe in biogenesis or abiogenesis? Needham – Abiogenesis He needed more information on how to do a good experiment

Who did this experiment and did he believe in biogenesis or abiogenesis? Pasteur - Biogenesis

The cell’s FUNCTION!

What are the four levels of cell organization starting from the cell?

What is it called when cells perform a specific function for an organism? Give some examples Cell Specialization Red blood cells blood cells Nerve cells

What is the semi-permeable, phospholipid bilayer (contains lipids and proteins) that regulates what goes in and out of a cell? Cell Membrane

Cell Wall

What does the cell wall do for a plant cell?

What 3 things pass through the cell membrane or cell wall easily? Diffusion Osmosis

What is located in the cell membrane to selectively allow things into and out of the cell? Proteins & Protein Channels

What is the jelly-like substance between the cell membrane and the nucleus? Cytoplasm

What is the control center of the cell? NUCLEUS

Nucleolus What is the organelle that is inside the nucleus and makes ribosomes?

What is the genetic material that is inside the nucleus called when it is threadlike? Chromatin (Hint: looks like spaghetti) What is the genetic material inside the nucleus called when it has condensed and preparing for cell division? Chromosome

What covers the outside of the nucleus and what are the holes called to allow ribosomes and RNA out? Nuclear Membrane and Nuclear Pores

What is the organelle that makes energy for the cell? What cells have it? Mitochondria Plant & Animal

What makes proteins in the cell? Hint:

What organelle makes food by photosynthesis for the plant cell? Chloroplasts

What are chloroplasts, leukoplasts, and chromoplasts called? Plastids

What is the large sac in a plant cell and small sac in an animal called that holds water and used for storage?

What digests and gets rid of unwanted things inside of the cell?

What is the organelle that is a folded membrane and moves material throughout the cell such as proteins, lipids, or carbohydrates? Transportation of Proteins Transportation of Lipids & Carbs

What is the organelle that packages and wraps materials to transport out of cell? Hint: Think of sending a gold necklace to your friend through the mail. Golgi Bodies or Apparatus

What are the microtubules covering the cell like hair used for movement? What are the microtubules that are whip-like and used for movement? Cilia Flagella

The movement of molecules from an area of HIGH → LOW concentration is called ________?________

Water movement across the cell membrane is called _____.

What is the transportation of particles across the cell membrane called that does NOT NEED ENERGY but NEEDS A PROTEIN CHANNEL?

What is the transportation of particles across the cell membrane from low to high concentration called that DOES NEED ENERGY (ATP) and NEEDS A PROTEIN CHANNEL? ACTIVE TRANSPORT

What is the transportation of particles into the cell called when the particle is too big to fit through the protein channel? Hint: Enters cell

What is the transportation of particles out of the cell called when the particle is too big to fit through the protein channel? Hint: Exits cell

Endocytosis and Exocytosis (moving big particles in or out of the cell) is also called _______ ________. Bulk Transport

When the solute concentration inside and outside of the cell is equal this is called______ and the cell shrinks, swells, or stays the same? Stays the same

When the solute concentration outside the cell is higher than inside the cell it is called______ and the cell shrinks, swells, or stays the same? Cell Shrinks

When the solute concentration inside the cell is higher than outside the cell it is called______ and the cell shrinks, swells, or stays the same? Cell Swells and could Burst

Name the 3 reasons cells cannot be the size of a basketball. 1.Geometry: Volume increases faster than Surface area 2.Practical aspects: Nucleus can’t handle that big of a job. 3.Specialization: Lots of smaller cells that do the same function can work together to perform a big job.

Be able to identify the organelles in plant and animal cells from various pictures!!!!

Be able to identify which organelles belong to Plant, Animal, or Prokaryotic Cells !
