Cell Basics
This is the smallest living part of an organism.
What is a cell?
This controls what enters and leaves the cell.
What is the cell membrane?
These cells have chloroplasts.
What are plant cells?
Cells use nutrients for these two purposes.
What are providing energy and building/repairing the cell?
What is an organism?
Organisms made of only one cell are called this.
What are unicellular organisms?
This jelly-like material fills the inside of the cell.
What is cytoplasm?
These cells do NOT have cell walls.
What are animal cells?
Cells break down food to release this.
What is energy?
This molecule contains a cell's genetic instructions.
What is DNA?
Plants, animals, and fungi are examples of these organisms.
What are multicellular organisms?
In plant and animal cells, this structure contains the genetic material.
What is the nucleus?
This structure surrounds plant cells and provides strength and support.
What is the cell wall?
As a cell gets larger, it eventually does this.
What is divide?
This process allows plants to make food using light.
What is photosynthesis?
These organisms have much smaller cells than plants or animals.
What are bacteria?
This structure gives plant cells support by filling with water.
What is the vacuole?
Name two structures found in plant cells but not animal cells.
What are chloroplasts and cell walls?
Cells in your eyes and heart are examples of these.
This means to make more of the same kind.
What is reproduce?
Name the three things all cells have in common.
What are a cell membrane, cytoplasm, and genetic material (DNA)?
This organelle is where photosynthesis happens.
What is the chloroplast?
Why don't animal cells perform photosynthesis?
Because they do not have chloroplasts.
Why do cells divide?
Because large cells have difficulty moving materials, so they divide into smaller cells.
Explain the difference between a cell wall and a cell membrane.
The cell membrane controls what enters and leaves the cell and is found in all cells. The cell wall is a rigid outer layer that gives support and is found in plants, fungi, bacteria, and some other organisms.
