cell structure and function

Which characteristic do most plants have in common?

• they are unicellular
• they are prokaryotic
• they produce seeds
•  they all have cell wall and chloroplast

Joy took the notes shown below while learning about cells.
• Forms boundary between a cell and the outside environment
• Controls the movement of materials into and out of the cell

• endoplasmic reticulum
• cell membrane
• cell wall
• nucleus

Which cell structure is correctly paired with its primary function?

• ribosome - movement
• mitocondria - energy production
• vacuole - cell division
• nucleus - storage of nutrients

Which organelle sorts, modifies and packages molecules for storage in the cell or secretion out of the cell?

• Mitochondria
• Smooth Endoplasmic Reticulum
• Rough Endoplasmic Reticulum
• Golgi Body

Which organelle is responsible for making proteins?

• Nucleus
• Nucleolus
• Lysosomes
• Ribosomes

What is a sac-like structure used to store water and nutrients? These are much larger in plant cells?

• Lysosomes
• Mitochondria
• Vacuoles
• Golgi Body

Number 1 is  a (the) - 

• Golgi Bodies
• Mitochondrion
• ribosome
• Nucleus

Kayla summarizes the cell theory to her class.  She states that all organisms are made up of one or more cells.  Which pair of statements correctly completes her summary? 

• The cell is the basic unit of all organisms, and all cells come from existing cells.
• The cell is the basic unit of all organisms, and all cells have the same parts.
• All cells are the same size, and the cell is the basic unit of all organisms.
• All cells come from existing cells and all cells have the same parts.

Unicellular organisms include bacteria, some algae, and some animals.  They live in virtually every environment on the planet.  Which of the following statements BEST describes the ratio of unicellular animals to multi-cellular animals?

• Multicellular organisms outnumber unicellular organisms only in terrestrial environments
• Unicellular and multicellular organisms exist in about the same number in both aquatic and terrestrial environments
• Unicellular organisms outnumber multicellular organisms in both aquatic and terrestrial environments.
• Multicellular organisms outnumber unicellular organisms only in aquatic environments.

What is the function of the cell membrane?

• Supports and protects the cell
• Controls the cell
• Controls what enters and leaves the cell
  
• Metabolic reactions occur here
