Cells and organelles lesson and quiz

Cells and Organelles lesson and quiz

Prokaryotes

• Earliest form of life on earth, first appeared about 3.5 BYA

• Unicellular with NO NUCLEUS

• Prokaryotes = Bacteria

• No organelles

• Some are heterotrophs(hunt for food), some are autotrophs(make own food)

• reproduce asexually

• Broken up into 2 kingdoms (Archaeabacteria and Eubacteria)

Multiple Choice

Which of the following is found inside a prokaryote?

• cytoplasm

• DNA

• ribosomes

• all of these

Open Ended

Are Bacteria are considered non-living?

Open Ended

Are Bacteria are prokaryotes or eukaryotes?

Eukaryotes

• Came after prokaryotes, Eukaryotes first appeared about 2.7 BYA

• Can be multicellular or unicellular

• Have A NUCLEUS

• Have organelles (tiny organ like structures)

• Eukaryotes are broken up into 4 kingdoms Animals, Plants, Fungi and Protista

• can reproduce sexually or asexually

Multiple Choice

Bacteria are an example of eukaryotes

• True

• False

Multiple Choice

Eukaryotes are complex cells with a nucleus and other membrane bound organelles.

• True

• False

Multiple Choice

Organisms that are made up of cells that lack a nucleus or membrane bound organelles are?

• Prokaryotes

• Eukaryotes

• Prokaryotes and Eukaryotes

• None of the above are correct.

Multiple Choice

All of the following are organelles in eukaryotes EXCEPT?

• Mitochondria

• Chloroplasts

• Golgi body

• All of the above are organelles in eukaryotes.

Cell Theory

• All organisms are made of cells

• The cell is the basic building block of life

• All cells come from pre-existing cells

• First cell identified by Robert Hooke

• 
  

• 
  

Multiple Choice

This is the smallest unit of an organism; it is enclosed by a membrane and performs life functions.

• Atoms

• Cells

• Matter

• Elements

Multiple Choice

What sort of evidence would support at least one of the components of the cell theory?

• Rocks and other nonliving things are not composed of cells.

• Cells are observed converting one form of energy into another.

• A microscope is necessary to make observations of nearly all cells.

• The origin of all cells observed can be traced to previous cells.

Multiple Choice

An amoeba is a one-celled organism. The cell theory states that which of the following characteristics of amoebas must be true?

• All amoebas have a regular, spherical shape.

• All amoebas move rapidly using cilia.

• All amoebas have organelles called chloroplasts.

• All amoebas come from other amoebas.

Multiple Choice

What part of the cell theory does the information in the table relate to?

• All living things are made up from cells.

• New cells come from existing cells.

• Cells contain genetic material in the nucleus.

• All cells perform similar necessary functions.

Organelles

• Nucleus: holds genetic material (DNA)

• Mitochondria: powerhouse of the cell

• Cell membrane : layer on outside of cell that holds cell together and lets things in and out

• Cytoplasm: gelly-like substance that holds all organelles

• Ribosomes :protein making factories

• Cell wall: provides structure and support (only in plant, fungi, and bacteria cells)

• Vacuoles: storage for cells( stores water, nutrients and waste) plants have a much larger vacuole

Organelles pt 2

• Lysosomes: gets rid of waste

• Rough E.R: makes proteins and transports them through the cell

• Smooth E.R: Makes hormones

• Golgi Apparatus( Golgi bodies) package proteins

• Chloroplast( plants only ) allows for photosythesis to occure

• 
  

• 
  

Multiple Choice

Based on the characteristics in the chart provided, what are the names of Organelle A and Organelle B?

• Organelle A is a cell wall. Organelle B is chloroplast

• Organelle A is chloroplast. Organelle B is a cell wall

• Organelle A is a cell wall. Organelle B is a cell membrane

• Organelle A is a cell membrane. Organelle B is a cell wall

Multiple Choice

Bianca has blue eyes like her father. Where is the trait found?

• genes within chromosomes in nucleus

• chromosomes within genes in cytoplasm

• nucleus within a gene in the chromosome

• cytoplasm within a chromosome

Multiple Choice

What organelle is called the "powerhouse" of a cell?

• mitochondria

• nucleus

• cell wall

• cell membrane

Multiple Choice

This organelle controls what goes in and out of plant and animal cells.

• Cell Wall

• Cell Membrane

• Chloroplasts

• Cytoplasm

Multiple Choice

outermost structure that gives support and shape to plant cells

• cell wall

• cell membrane

• mitochrondria

• cytoplasm

Multiple Choice

packages and distributes proteins

proteins may be modified here

• golgi body

• chloroplast

• ribosomes

• lysosome

Plants vs Animal cells

• Share most organelles

• Animal cells do not contain chloroplast, cell wall or a large central vacuole

• Plants go through photosynthesis which means that they must have chloroplast to store the radiant energy from the sun

Multiple Choice

This organelle is where plants do photosynthesis.

• Mitochondria
• Lysosome
• Chloroplast
• Vacuole

Multiple Choice

Which of these organelles do animal cells not have?

• Nucleus
• Chloroplasts
• Cell membrane
• Lysosome

Multiple Choice

What type of cell is pictured above?

• Plant Cell

• Animal Cell

• Mr. Rodriguez cell

• what a cell?

Multiple Choice

What shape are most plant cells?

• round

• rectangular

• triangle

• rhombus

Multiple Choice

Both a plant and animal cells have a cell wall

• Only plant cells have cell walls

• only animal cells have cell walls

• all cells have cell walls

• No cells have cell walls
