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?

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.

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.
