As the basic units of life, cells are living systems that carry out all of the functions needed to sustain life. Which process is common to all cells?
All cells get nutrients from the air.
All cells need and use energy
All cells make their own food
All cells allow organisms to move
What is the significance of cell division?
to make ATP
to prevent replication
to repair and replace other cells
to make glucose
A student watched a video and found out that red blood cells (RBC) have a different function than white blood cells (WBC). Based on what the student learned from the video, which of the following is most likely true about these types of cells?
. RBC and WBC use carbon dioxide to release energy.
. RBC and WBC have different structures
. RBC and WBC carry oxygen.
RBC and WBC fight diseases.
Which choice best shows what all cells need to survive?
food, water, oxygen, and energy
food, water, energy, and sunlight
. food, water, energy, and waste removal
food, water, carbon dioxide, and heat
Which of the following best describes why a cell would not be able to reproduce if its nucleus were damaged?
The nucleus is responsible for creating the energy used to perform cell division.
The nucleus is responsible for housing the genetic information needed for cell division.
The nucleus is responsible for letting the materials in that are needed for cell division
The nucleus is responsible for creating the sugars needed to perform cell division.
Which organelle may often be referred to as the "gate keeper" because it controls what goes in and out of the cell?
the cytoplasm
the nucleus
the cell membrane
the mitochondrion
Which statement best compares multi-celled organisms to single-celled organisms?
Multi-celled organisms always get energy differently than single-celled organisms.
Single-celled organisms carry out fewer life functions than multi-celled organisms.
Single-celled organisms are always larger than multi-celled organisms, but multi-celled organisms always perform more functions.
Multi-celled organisms have many cells that perform different functions, and single-celled organisms perform all functions within one cell.
Multi-celled organisms have many cells that perform different functions, and single-celled organisms perform all functions within one cell.
Animal cells do not contain cytoplasm because animals use lungs to conduct respiration.
Animal cells do not contain chloroplasts because animals do not conduct photosynthesis.
Animal cells do not have mitochondria because animals do not produce their own energy.
Animal cells do not have cell membranes because animals use bone structures for support.
Vacuoles are cell structures that are sometimes compared to warehouses. They have the ability to store things such as water and nutrients, and in some cases provide rigidity for the cell. Certain types of cells utilize vacuoles more than others. In what type of cell would you expect to find the largest vacuole?
a cactus cell
a human cell
a worm cell
a mushroom cell
Which characteristic is missing from the table?
have a cell life of five to ten days
perform photosynthesis to make food
get rid of waste to maintain homeostasis
use chloroplasts to convert sunlight into energy
Muscle cells in athletes often have more mitochondria than muscle cells in non-athletes. What can be inferred from this observation?
Muscle cells in athletes have a smaller supply of cell proteins than muscle cells of non-athletes
Muscle cells in athletes reproduce less frequently than muscle cells of non-athletes.
Muscle cells in athletes have nuclei containing more DNA than nuclei in muscle cells of non-athletes.
Muscle cells in athletes have a greater demand for energy than muscle cells of non-athletes.
Mercedes created a table to show the functions of different cell structures. What error did Mercedes make when creating her table?
Mercedes switched the functions of the cytoplasm and the cell membrane.
Mercedes switched the functions of the mitochondria and the chloroplast
Mercedes switched the functions of the nucleus and the cell membrane
Mercedes switched the functions of the chloroplast and the nucleus.
If a cell were compared to a school, which part of the school would represent the cell's nucleus?
the classroom walls because they give the structure to the school
the cafeteria cooks because they make food for the entire school
the principal because he or she controls all the activity in the school
the fence because it controls what enters and exits the school
