You have been asked the class to make a cell city model. Which building or business in the city could represent the mitochondria, and why?
city dump- waste storage
City hall- control center
roads- transportation system
power company- produces energy
Which cell structure is the gatekeeper, controlling what goes in and out of the cell?
Nucleus
Vacuole
Cell membrane
Endoplasmic Reticulum
Living matter is at least sixty percent water. It makes sense, then, that cell membranes are made of phospholipids because
Phosphates dissolve in water
The bilayer acts to repel water.
The lipids form an insoluble barrier.
The lipids mix easily in a water environment.
All BUT one is a function of the cell wall. That is
Provides support
Provides protection
Transfers genetic materials
Regulates the passage of materials
The cell membrane helps to control what enters and leaves a cell. Which of these substances, which accounts for about two-thirds of a cell's mass, is constantly moving in and out of the cell?
Carbohydrates
Protein
Waste
Water
Where are chromosomes found in an animal cell?
Inside a gene
In the cytoplasm
In a strand of DNA
Inside of the nucleus
_______ is a jellylike substance in both the animal and the plant cell containing important chemicals and acts like a matrix for the cell organelles.
Chloroplast
Cytoplasm
Mitochondria
Vacuole
Plants have large central vacuole. What is the function of the central vacuole in plants?
The central vacuole stores water.
The central vacuole contains DNA.
The central vacuole controls division of the cell.
The central vacuole manufactures proteins for the cell.
Plant and animal cells have a lot in common. In fact, they are more alike than different. What organelles can you find in BOTH types of cells?
membrane, nucleus, cytoplasm,
membrane, chloroplasts, nucleus
cell wall, cell membrane, nucleus
cell membrane and cell wall, chloroplasts
Lipids, mainly phospholipids, make up the bulk of the cell membrane. How is the structure of the phospholipid so perfectly paired to the function of the cell membrane?
Phospholipids are bulky/large molecules that prevent all molecules from entering/exiting the cell.
The polar tails of the phospholipids provide the barrier between the exterior/interior hydrophilic environments.
Lipids contain high energy bonds, and these bonds help to provide the energy to move molecules across the membrane.
The head of the phospholipid, which is hydrophilic, helps to control the movement of large hydrophobic molecules, and the tails of the phospholipid, which are hydrophobic, help to control the movement of large hydrophilic molecules.
_____ and _______ are organelles that definitely arose from endosymbiosis.
Rough ER and Smooth ER
Mitochondria and Golgi Body
Chloroplast and Golgi Body
Mitochondria and Chloroplast

Matthias Schleiden
Theodor Schwann
Robert Hooke

Cristae
Matrix
Integral membrane proteins
The noodle-like form of DNA is:
Chromatin
Chromosome
Chromatid
