Multiple Select

In Biology, what are cells? (TWO ANSWERS)

• The building blocks of life.

• The smallest unit of all matter.

• The smallest known unit that can be classified as living.

• Tiny compartments that are in jails.

Multiple Choice

True or false? There are many different types of cells and each cell carries out a very specific job.

• True

• False

Multiple Choice

Which sentence best describes a multicellular organism?

• A living think that is composed of one cell.

• A type of creature that likes to eat multiple grains.

• A living thing made up of many different types of cells.

• A bacteria or amoeba..

Cells are the basic building blocks of life. There are two categories of cells: prokaryotic and eukaryotic.

Characteristics of a prokaryotic cell:

*Lack a nucleus.

*Contain a nucleOID.

*Lack membrane bound organelles.

*Single-celled (unicellular)

*Earliest known life.

*Generally very tiny!!

*Have BOTH a cell wall and a plasma membrane

*Contain cytoplasm and ribosomes.

*BACTERIA , plankton, amoeba

Multiple Choice

Do prokaryotic cells have a cell membrane?

• Yes

• No

Open Ended

Another word for a prokaryotic cell is ______________.

Multiple Choice

Prokaryotes are known also known as unicellular organisms. This means that they are made of how many cells (think of the prefix UNI and examples of unicorns and unicycles)

• 3 cells

• millisons of cells

• 100 cells

• 1 cell

Eukaryotic Cells.

• Animal cells

• Plant cells

Characteristics of Eukaryotic

• Generally much larger than prokaryotic

• Have a TRUE NUCLEUS that contains the cell's DNA (genetic material)

• Contain membrane-bound organelles

• Contain cytoplasm (like ALL cells do)

• ANIMAL and PLANT CELLS (for our purposes)

Multiple Choice

What do eukaryotic cells have that prokaryotic cells do not have?

• Cell membrane

• Ribosomes

• A nucleus

• Cytoplasm

Multiple Choice

What is contained in a eukaryotic nucleus?

• The cell wall

• DNA (genetic material for the cell)

• mitochondria

Multiple Choice

What is the jelly-like substance that is found is ALL cells called?

• ribosomes

• grape jam

• cytoplasm

• vacuoles

Multiple Choice

True or false? Both plant and animal cells contain a cell membrane?

• True

• False

Multiple Choice

True or false? Both plant and animal cells contain a cell wall?

• True

• False

Cell Wall

• ONLY found in PLANT CELLS!

• Made of a substance called CELLULOSE

• Rigid (non-flexible)

• Very porous (having tiny holes through which liquid or air may pass.)

• Provides structure for plant cells

• Plants do NOT have skeletal systems and NEED cells walls to provide structure

Cell Wall Analogy

Think of cells walls as green scrubby pads. They are rigid AND highly porous.

Cell Membrane

• Flexible

• Provide protection for cells

• Selective permeability (lets only certain things in and out of the cell)

• Serve as the "gatekeepers" or "protectors" of cells.

• Found in BOTH prokaryotic and eukaryotic cells.

• Made of FATS and PROTEINS

Cell Membrane Analogy

Think of cell membranes as balloons. They are flexible and provide protection for the cell. They are also permeable.

Multiple Choice

What are cell WALLS made of?

• cytoplasm

• cellulose

• plastic

• lysosomes

Multiple Choice

What is the purpose of the cell wall?

• To provide structure for a plant cell.

• Selective permeability.

• Cell replication.

Multiple Choice

What does SELECTIVE PERMEABILITY mean?

• Only allows specific gases & liquids through

• Free exchange of all gases and liquids

• Very porous (lots of openings)

• None of these

Multiple Choice

Which of these performs selective permeability?

• Cell wall

• Cell membrane

• Nucleus

• flagellum

Mitochondria

Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. 

Nucleus

The part of the cell which contains the genetic code, the DNA. The nucleus is small and round, and it works as the cell's control center.

Vacuole

‘Recycling Center’ : (breaks down food into smaller particles) AND ‘Storehouse’ (stores water, food & other necessary material in the cell)

Endoplasmic Reticulum

Passageways to help process & store energy (food) 

Ribosomes

‘Maker’: produce proteins

Golgi Apparatus

‘Packer/Distributor: ’ (just like Amazon) gets stuff to where it is needed INSIDE of the cell

Lysosome

‘Delivery’: sends packages of nutrients out of cell

Chloroplasts

‘Capture’ energy from the Sun (found in leaves to make food from energy).

ONLY FOUND IN PLANTS

Remember this?

This should be in your notes! It is a "quick guide" to your organelles. If you don' have your notes complete, why? You will PASS THE TEST if you have your C-Notes completed!

Multiple Choice

True or false? Chloroplasts are in animal cells?

• True

• False

Multiple Choice

Mitochondria are which of the following?

• They produce proteins

• The recycling center of the cell

• The powerhouse of the cell that converts food into energy.

• The packaging center of the cell.

Multiple Choice

Chloroplasts are necessary for what process?

• mitosis

• diffusion

• photosynthesis

• none of these

Multiple Choice

True of false? Cytoplasm is made of mostly water and salt?

• False

• True

Multiple Select

What TWO functions do the vacuoles perform?

• capturing energy from the sun

• Breaking down food into smaller particles

• Selective permeability

• Storing water, energy, and other materials for the cell

Multiple Choice

Endoplasmic reticulum do what?

• Produce proteins for cells

• Transport nutrients throughout the cell

• Provide structure for the cell.

• Are the passageway to store and process energy

Multiple Choice

Golgi Apparatus are organelles that do what?

• Pack and distribute materials to where they are needed IN the cell?

• ‘Passageway’ to help process & store energy (

• ‘Delivery’ sends packages of nutrients OUT of cell

Multiple Choice

Is a nucleOID the same as a nucleUS?

• Yes

• NO

Multiple Choice

What is the whip-like tail on this bacteria picture called?

• American flag

• Flagellum

• Jello

• Nucleus

Multiple Choice

Respiration (the opposite process of photosynthesis) involves

• a. the production of energy (ATP).

• b. Sun energy.

• c. converting food (sugar, carbohydrates) to energy in the form of ATP.

• d. Both a and c
