Cell Basics
What is the smallest basic unit of life.
A cell
Which organelle is known as the powerhouse of the cell?
Mitochondria
Which type of cell has a cell wall: plant or animal?
Plant Cell
What is the term for an organism made of only one cell?
Unicellular Organism
In diffusion, do molecules move from high to low concentration or low to high concentration?
High to low concentration
Are cells living or non-living?
Which organelle is the command centre of the cell?
Nucleus
Which type of cell usually has a larger vacuole?
Plant Cell
What is an organelle?
A specialized structure inside a cell that performs a particular job.
Which type of solution does an animal cell prefer?
Hypotonic solution
Put these in order from smallest to largest: organ, tissue, cell, organ system.
Cell -> Tissue -> Organ -> Organ System
What structure surrounds an animal cell and controls what enters and leaves?
Cell Membrane
In an animal cell, where is the nucleus located?
Near the center
What is a tissue made of?
A group of similar cells working together.
What is osmosis?
The movement of water across a selectively permeable membrane.
What is a group of similar cells working together called?
What is the jelly-like material inside a cell called?
Cytoplasm
What rigid structure supports and protects a plant cell?
Cell Wall
What is the difference between a unicellular organism and a multicellular organism?
A unicellular organism has one cell, while a multicellular organism has many cells.
Isotonic solution is prefered by a _____ cell.
Plant
How do cells help make up a complex organism?
Cells form tissues, tissues form organs, and organs work together in organ systems.
Which organelle stores materials and is generally much larger in plant cells?
Give two differences between a typical plant cell and an animal cell.
Plant cells have a cell wall and usually a large central vacuole. Plant cells also have chloroplasts, while animal cells do not.
Explain the difference between a cell, an organelle, and a tissue.
A cell is the basic unit of life. An organelle is a specialized structure within a cell. A tissue is a group of cells working together.
What is the difference between diffusion and osmosis?
Diffusion is the movement of particles from high to low concentration. Osmosis is specifically the movement of water across a selectively permeable membrane.
