Unit 2: Cells
The Cell Theory The cell is the basic unit of structure and function (a.k.a. – life) All living things are made up of 1 or more cells Cells come from other, preexisting cells (a.k.a. – reproduction)
What is a cell? It is the smallest unit of life that carries out life functions Animal Cell Plant Cell
What’s Inside? Organellestiny structures within a cell that perform specific jobs to keep the cell alive
Important Organelles Cytoplasm - gel-like material inside cells
Important Organelles – Continued…Cell Membrane - protects cell and gives it shape and controls what enters and leaves the cell. Cell Membrane
Important Organelles – Continued…Nucleus - directs cell activities (brain) Nucleus
Important Organelles – Continued…Endoplasmic Reticulum (ER) - movement of materials throughout cell ER
Important Organelles – Continued…Ribosome - makes proteins Ribosomes
Important Organelles – Continued…Mitochondria - the powerhouse of the cell (converts food into energy for the cell) Mitochondria
Important Organelles – Continued…Chromatin/Chromosomes (DNA) - contains genetic information (inside the nucleus) Chromatin
Important Organelles – Continued…Chloroplast - takes energy from the sun and makes food for the PLANT cell (not found in Animal Cells) Chloroplast
Important Organelles – Continued…Cell Wall - supports and protects PLANT cells (not found in animal cells) Cell Wall
Important Organelles – Continued…Vacuole - storage of food and water Vacuole
Important Organelles – Continued…Golgi Body - packages and moves proteins Golgi Body
Important Organelles – Continued…Lysosome - digests wastes Lysosome

A Tour Through the Living Cell 7 th Grade. Two Types of Cells All living things are made of cells. All cells can be put into two groups: animal cells.
Nucleolus Makes ribosomes in the nucleus. Chromatin Contains DNA; coils into chromosomes.
Cell structure Review A cell that has no nucleus or membrane bound organelles is a Plant cell Animal cell Prokaryotic cell Eukaryotic cell.
