To compare and contrast eukaryotes and prokaryotes. To compare and contrast animal and plant cells.
Learning objective:
What is the difference between single celled and multicellular organisms?
What is the basic unit of life in all living organisms?
What is the primary structural difference between eukaryotic and prokaryotic cells?
The nucleus of a cell is made up of genetic material, also known as DNA, which is what determines the characteristics of the cell. Cells contain tiny structures called organelles, which are specialized to perform certain functions within the cell.
Did you know?
Cell Membrane: The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. Cell Wall: The cell wall is a thick layer found on the outside of plant cells, bacteria cells, fungi cells, and some other eukaryotic cells. Its primary function is to provide structural support and protection for the cell. Cytoplasm: Cytoplasm is the gel-like material inside the cell membrane that contains the organelles and other cellular structures.
Concepts:
Which type of cell lacks a nucleus?
- Plant cell
- Eukaryotic cell
- Prokaryotic cell
'Plasma membrane' and 'cell membrane' are interchangeable terms. What is their function?
- To produce energy for the cell.
- To control what enters and exits the cell.
- To store genetic information.
Work together in pairs: What are three main structures found in most eukaryotic cells?
Plant cells are eukaryotic cells, meaning they have a nucleus and other membrane-bound organelles. Plant cells have a cell wall made of cellulose that acts as a protective layer and helps them maintain their shape. Plant cells contain chloroplasts, which are the sites of photosynthesis and the production of food for the plant.
Plant Cells
Animal cells are made up of different organelles that work together to keep the cell functioning. Organelles include a nucleus, endoplasmic reticulum, mitochondria, golgi bodies and more. These cells are found in all multicellular organisms, such as plants and animals.
Animal Cells: An Introduction
Plant cells contain chloroplasts which are responsible for converting light into energy during photosynthesis. Animal cells have lysosomes which contain digestive enzymes that break down organic material. Plant cells have a cell wall which is composed of cellulose, a strong sugar molecule, while animal cells do not have a cell wall.

Plant cells have a cell wall and chloroplasts, which are used to make food from sunlight. Animal cells lack a cell wall and chloroplasts, and must get food from other sources. Both plant and animal cells have a nucleus, cytoplasm, and other organelles.
