Topic 4 – The Cell and Cell structuresPg. 267 – 273

Cell Structures and their functions (pg. 267­270)Fill in the function of each organelle in the chart below from pgs 267­270

Name of Organelle Function Analogy

Cell Wall Provides strength and support to plant/fungi cells

Cell Membrane Regulates and controls the passage of materials in/out of the cell

Nucleus Contains DNA. Regulates all cellular activities

CytoplasmGel inside cells that contains water and nutrients necessary for cell functionsCushions organelles

Chloroplasts Contain Chlorophyll (green pigment)Uses solar energy for photosynthesis

Vacuoles/VesiclesStorage organelles for fats, wastes, nutrients, hormonesTransports them out of cell

Smooth Endoplasmic Reticulum

Transport and production of fats and oils

Rough Endoplasmic Reticulum

Tubes that run from nucleus, transport materialRibosomes are attached

Ribosomes Make Amino acids into proteins

Lysosomes Contain enzymes for digestion and defense against bacteria/viruses

Golgi Body (apparatus)

Modifies molecules made by cell and packages them for transport

Mitochondria Converts sugar into useful energy that the cell needs

The Chemical Composition of Cell Structures: (pg. 271­272)

1. The major elements that make up cells are:a. carbonb. hydrogenc. oxygend. nitrogen

2. These elements are organized into four major organic compounds:

Example of Compound

Lipids Fats and oils

Carbohydrates Sugars, starch, cellulose

Proteins Muscle fiber

Nucleic Acids DNA (genetic material)

1.   Water   is the solvent  within and outside the cell. It is needed for biochemical reactions.

2. Two similarities between plant and animal cells are:

a. Both have a cell membrane and a cytoskeleton

b. Both have genetic material (DNA)

3. Six differences between plant and animal cells are:a. Animal cells have centrioles to help with cell division

b. Plant cells have a  cell wall made of cellulose, animals have no cell wall

c. Plant cells have a chloroplast, containing  which is performs          photosynthesis

d. Animal cells have specialized compounds, for example, hemoglobin in red blood cells and cholesterol

e. Plant cells store energy as starch or oils, Animal cells store energy         as glycogen (a type of carbohydrate) or fat

f. Plant cells have one  large central vacuole. Animal cells have small vacuoles and vesicles.

Assignment: 

Questions # 2, 5, 6, 8 on pg. 273 on a separate piece of paper

Major Organic Compound
