Which function do the lipids in a cell control?
a protective membrane
hold genetic information
transport
communication
Which two macromolecules offer energy storage to the cell?
lipids and nucleic acids
proteins and carbohydrates
nucleic acids and proteins
lipids and carbohydrates
Which substance makes up the macromolecule carbohydrate?
amino acids
vitamins
nucleotides
sugar
Which best explains the function of a cell membrane?
offers protection from the outside environment
provides a framework to help the cell move
transforms energy in the cell into ATP
removes viruses from inside the cell
Photosynthesis occurs at the cell level. Which organelle is necessary for photosynthesis?
Golgi apparatus
chloroplasts
mitochondrion
rough endoplasmic reticulum
Which organelle prepares proteins into vesicles to transport from one area of a cell to another?
golgi apparatus
chloroplasts
mitochondrion
rough endoplasmic retivulum
Which is used to make proteins in the cell?
water
ribosomes
DNA
lipids
What is the main difference between a prokaryotic cell and an eukaryotic cell?
Only prokaryotic cells have vacuoles.
Eukaryotic celss are smaller than prokaryotic cells.
Prokaryotic cells have many organelles, each with their own specialized functions.
Only eukaryotic cells have its genetic material surrounded by a membrane.
What is the function of a lysosome?
food storage
preparing proteins
making food
recycle material
What is the difference between rough endoplasmic reticulum (ER) and smooth endoplasmic reticlum (ER) ?
Rough ER has lysosomes covering the organelle while smooth ER does not.
Rough ER has ribosomes covering the organelle while smooth ER does not.
Smooth ER releases energy while rough ER absorbs energy.
Rough ER is found on the inside of the cell while smooth ER is found on the outside of the cell.
What is the main difference between active transport and passive transport?
During active transport the water inside the cell is used to transport substances throughout the cell. Passive transport uses the cell's cytoplasm to move substances around the cell.
Passive transport moves substances throughout the cell without using the cell's energy and active transport moves substances using the cells energy.
Active transport moves substances from higher concentrations to lower concentrations and passive transport moves substances from lower concentrations to higher concentrations.
Passive transport moves substances that are too large to get through the cell membrane by forming a vesicle inside the cell and active transport forms the vesicle on the outside of the cell.
Which substance is broken down during glycolysis?
glucose
carbon dioxide
cytoplasm
water
Which substance is released as a waste product during photosynthesis?
glucose
carbon dioxide
cytoplasm
oxygen
