2 Atoms made Elements. Elements make molecules

3 Molecules are: Groups of elements held by chemical bonds (compounds)

4 Atoms made Elements. Elements make molecules Molecules make Cells Cells make tissue Tissues make Organs Organs make up Organ systems Organ systems make up an Organism

6 What are the most common elements in LIVING THINGS?
C,H,N,O,P,S They make cells Basis of organic chemistry

7 What are the most common molecules in LIVING THINGS?
Protein Lipid Carbohydrates Nucleic Acids

8 Proteins Molecules made of amino acids
Build and repair body structures Create enzymes

9

10 Lipids “fat” molecules Store energy (oils, waxes, fats)
A PHOSPHOLIPID: a molecule of phosphorous and lipid which is the main building block for cell membranes

11 Carbohydrates Sugars, starches, fibers Energy storage and release

12 Nucleic Acids Cell’s genetic information is stored within
Made of nucleotides DNA is a common type

13 DNA

14 Atoms and elements can make up cells

15 Cells: the smallest basic units that can preform all life processes
Cells are made of atoms They make everything an organism needs for survival

16 CELL THEORY

17 Phagocytosis cytoplasm engulfs large particles

18 2 types: Eukaryotes vs. Prokaryotes Multicelluar vs Unicelluar

19 Prokaryote: a single celled organism
Prokaryote: a single celled organism. Does not have a nucleus or organelles (ex./ bacteria & archea)

20 Eukaryote: an organism made of cells which have a nucleus and organelles (ex:/ animals, plants, fungi, protists)

21 ORGANISM A living thing; anything that can carry out life processes independently

22 CELL THEORY 1665: first cells observed recorded . Named “cells”
1673: Van Leeuwenhoek observed single celled organism in pond water, and observed cells in blood using a microscope 1839: Schwann and Schleiden observed plants and animals made of cells. Proposed all living things are made of cells 1858: Rudolph Virchow observed cell division and proposed all cells come from other cells and cell processes.

23 Cells are small Transportation of materials is easy when
you have a large surface to volume ratio

24

25

26 Cell Membrane Phospholipid layer that covers the cell’s surface Provides protection for the cell Allows the active and passive transport of materials in and out Outerlayer; Acts as a barrier between the inside and outside of a cell Semi-permeable

27 Cytoplasm The area inside the cell, including the (watery-medium) fluid located inside the membrane around the organelles

28 NUCLEUS The center of an atom: containing protons and neutrons
The membrane-bound organelle in a cell which contains the genetic material (DNA). It has a role in such processes as growth, reproduction and metabolism.

29 Ribosomes Follows DNA as a code Uses amino acids Synthesizes Proteins
(found in eukaryotes and Prokaryotes)

30 Eukaryotic cells are bigger and more complex

31 Golgi Complex receives protein/lipids sorts, packages, and ships them inside and out of the cell

32 Endoplasmic Reticulum Smooth- no ribosomes, makes lipids, breaks down toxins Rough- ribosomes (synthesize protein)

33 Mitochondria double membrane organelle with matrix releases energy stored in food CELLULAR RESPIRATION

34

35 Lysosomes digests cell waste

36 Cytoskeleton fibers/filaments help support cell help movement of cell

37

38 Cell Walls

39 Large Centriole Vacuole
Large in plants, small in animals Lots of water, supports the cell

40 Chloroplasts Contain chlorophyll (photosynthesis: using the Sun’s energy to create energy As glucose sugar)

41 Compare/ contrast Animal vs plant Eukaryote vs Prokaryote

42 Nucleolus: synthesizes ribosomes

43 Cells make Tissues Cells are specialized
Groups of specialized cells work together as a tissue: Epithelial- protective tissue (Integumentary) Connective- hold other tissues together, can expand and contract Muscle- muscles and bones. Helps protect organs. Allows movement and structure of body nerve tissue- spine, brain and central nervous system

44 Tissues make up Organs

45 Organs make up Organ Systems
Circulatory system Digestive system Skeletal system Muscular system Excretory system Reproductive system

46 Organ Systems make up an organism
