1. Do Now Please complete the following: Put belongings away
Have vocabulary on your desk for a check
Turn to your organelle note sheet (with the 2 cell diagrams)

2. 3. Cytoplasm
Thick-fluid solution filling cells, enclosed by the membrane
Site of most chemical reactions

3. 4. Nucleus Controls all the activities of the cell Brain of the cell
Contains Chromosomes (DNA)
Brain of the cell
Surrounded by a Nuclear Envelope, separating it from the rest of the cell
Contains Nucleolus, lil’ Nucleas
Makes RNA

4. 5. Ribosomes Site of protein synthesis
Where proteins are made
Can be floating free in cytoplasm or attached to Endoplasmic Reticulum
Helps to transport proteins
Maze of passage ways

5. 6. Chloroplasts* **Not found in animal cells** Site of photosynthesis
Contains green pigment Chlorophyll

6. 7. Mitochondria Site of cellular respiration “Power house” of the cell
Where chemical reactions occur producing energy (ATP)
“Power house” of the cell
Contain their own DNA and can replicate
Sometimes are linked with ribosomes

7. 8. Vacuole Stores nutrients for energy and wastes
Large, round sac-like structure generally storing water
MUCH larger in plant cells which can have central vacuole.

8. CELLS and how they relate to Life Functions

9. The Cell Theory The cell is the basic unit of structure.
All living things are made up of one or more cells.

10. The Cell Theory
A cell is the smallest unit that is capable of performing all the life functions.

11. The Cell Theory All cells come from pre-existing cells.
Through mitosis one cell makes 2 cells, etc.

12. Exceptions to the Theory
Viruses: Cannot replicate except in a host
Mitochondria & Chloroplasts have their own DNA and can replicate

13. Cell Membrane Helps control:
Regulation: Membrane allows nutrients and small molecules in. Keeps large molecules and bad stuff out

14. Cell Membrane Excretion: All waste products exit through the membrane
Carbon dioxide

15. Cell Membrane Transport: materials are ABSORBED
Nutrition The ingestion of food

16. Cell Membrane
GROWTH The membrane must increase in size

17. Cytoplasm Synthesis – lots of molecules are made here
Growth – an increase in the number of molecules = growth
Transport : diffusion

18. Chloroplasts Only in plant cells, convert sun light to energy
Synthesis site of PHOTOSYNTHESIS
Reproduction they have their own DNA and can make copies of themselves
Synthesis make proteins at their own ribosomes

19. Mitochondria Respiration site of aerobic respiration
Reproduction they have their own DNA and can make copies of themselves
Synthesis make proteins at their own ribosomes

20. Nucleus Reproduction Mitosis starts here
Synthesis - makes new DNA – chromosomes
Regulation the DNA controls all cell activities

21. Ribosome Synthesis makes proteins
Growth an increase in the number of molecules leads to growth
Protein
Ribosome

22. Vacuole
Excretion – stores wastes
Nutrition – stores food
