Features of Life and the Cell


2/13

Chapter 2.1 Notes8 features of Living Things

ReproduceSexual- 2 parents

Asexual- 1 parent

2. Grow- increase in size

3. Develop- grow parts

4. Need Food

Herbivores- plant eaters

Carnivores-meat eaterOmnivores- eat both plants and animals

Producers- Green plants

5. Use Energy

Cellular respiration food is broken down andenergy is givenoff

C6H

12O

6+ 6O

26 CO

2+ 6H

2O

Sugar+ oxygen = Carbon dioxide + water

6. Made of cells

7. Respond

8. Are adapted to their environments

The Cell Theory

1665- Robert Hooke Cells

19th Century Schleiden and Schwann

came up with the cell theory.

1. All living things are made of cells

2. Cells are the basic units of structure and

function3. All cells come from othercells

Chapter 2.2 Notes

Cell parts (organelles)

1. Cell membrane (door to cell) gives cell shape andholds the cytoplasm. Allow things in and out ofthe cell.

2. Nucleus (brain) controls cells activities.

3. Nuclear membrane (door to nucleus) surroundsnucleus lets things in and out of nucleus.

4. Golgi apparatus (packs) packages and storeschemicals.

5. Nucleolus- makes ribosomes.6. chromosomes contains DNA information.

7. Cytoplasm (where chemical reactions occur)clear, jellylike material between the cellmembrane and the nucleus.

8. Endoplasmic Reticulum- ER- (roads) movesmaterials around cell.

9. Ribosomes- make protein.

10.Mitochondria (powerhouse) make energy.

11.Vacuole (storage) liquid-filled space for

storage.12.Centrioles (reproduction) used during

reproduction.

13.Chloroplast- (make food) have green pigment

called chlorophyll. Plants only.14.Cell wall (support) thick outer covering that

protects and supports plants. Plants only.

Chapter 2.3 Notes

Diffusion- is the movement of a substance

from a large (high) amount of it to where

there is a small (low) amount of it.


11/13

Osmosis- the diffusion of water.

The cell membrane has pores.


12/13

Cell- basic unit of life

Tissue- group of cells working together. Organ- group of tissues.

Organ system- group of organs working together.

Organism- group of organ systems working together.
