Plant Cell: Cell Wall.

(Looking at the large green part in the picture) The cell wall is the outermost part of a plant cell, that protects the organelles within the cell and helps keep its shape. Plants do not have bones, so the the many cells that make up plants are like bricks, which gives structure to the plant.

Plant and animal Cell: Cell membrane

(Plant; looking at the yellow part on the inside of the cell wall. Animal; looking at the orange on the outside.) The cell membrane is in both plant and animal cells. Although it is in two different types of cells it has the same job in both. The cell membranes' purpose is to provide protection for the cell, and to control what enters and leaves the cell.

Plant and Animal Cell: Nucleus

(Looking at the circular organelle in both cells) The nucleus is in both the animal and plant cell. It has the same job, and it is to inform the other organelles of what to do. This organelle is important because it holds the DNA, or genetic material for the cell.

Plant and Animal cell: cytoplasm

(Looking at the color that fills in the inside of the cell) The cytoplasm fills the cell and keeps the organelles in their place. It is also responsible for helping the cell keep its shape.

Plant and Animal cell: Ribosome

(Looking at the small black dots in the cell) The Ribosomes follow the nucleus' instruction.

Plant and Animal cell: Mitochondria

(Looking at the white oval shape in the Plant cell, and the orange oval shape in the Animal cell) The Mitochondria creates ATP energy that the cell needs to run, and breaks down sugar to release energy.

Plant and Animal Cell: Vacuole

(Looking at the big blue shape in the Plant cell, and although this diagram does not show it, Animal cells do have a vacuole, it is just small.) The vacuole stores water that the cell needs to live. It also stores waste so the cell isn't contaminated.

Plant and animal cell: Golgi Body

(Looking at the purple squiggly thing in the animal cell, and the red squiggly thing in the plant cell.) The Golgi body packages lipids and proteins.

Animal Cell: Lysosome

(Looking at blue and greenish half circle in the animal cell.) The Lysosome breaks down waste and uses poisons to clean up the cell. Then they salvage materials the cell might be able to use.

Plant Cell: Chloroplast

(Looking at the green tear drop shaped organelle in the Plant cell) The chloroplast creates energy through photosynthesis.

Cell Comparison: Eukaryotic cells VS Prokaryotic cells


Prokaryotic cells do not contain membrane-bound organelles or a nucleus, mitochondria, chloroplasts, or cell walls.


Eukaryotic cells contain membrane-bound organelles, such as the nucleus.

Cell Theory!

  1. All living things are composed of cells
  2. Cells are the basic units of life
  3. All existing cells come from pre-existing cells

Photosynthesis VS Respiration

Photosynthesis and Respiration are reactions that compliment each other in the environment. They are in basically the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen through the respiration process glucose and oxygen yield carbon dioxide and water.

Photosynthesis Equation

6CO2 + 12H2O + light --> C6H12O6 + 6O2 + 6H20

Respiration Equation

6O2 + C6H12O6 --> 6CO2 +6H2O + ATP (energy)
