Front 1

Exercise 1

Back 1

Measurements, Lab Techniques, and Biological Organization

Front 2

Basic Metric Unit of Length

Back 2

1 meter (m)

Front 3

Basic Metric Unit of Volume

Back 3

1 liter (l)

Front 4

Basic Metric Unit of Mass

Back 4

1 gram (g)

Front 5

Interpolate

Back 5

To estimate a specific, missing intermediate value.

Front 6

Surface Area of a Rectangle Block (cm2)

Back 6

Is equivalent to the sum of the surface areas of its six sides.
2 (l x w) + 2 (l x h) + 2 (w x h)

Front 7

Volume of a Rectangle Block (cm3)

Back 7

l x w x h

Front 8

Surface Area to Volume Ratio

Back 8

SA/Vol Ratio (cm2/cm3)

Front 9

Relationship between SA/Volume Ratio to Volume

Back 9

As the volume increases, the SA/Volume ratio decreases.

Front 10

Why is SA/V ratio important in biology?

Back 10

Can affect an organism in many ways such as exposure to their environment and ability regulate body temperature.

Front 11

Procedure to Calculate Volume by Displacement

Back 11

1. Obtain cylinder.
2. Fill cylinder with water and record level of water.
3. Submerge object.
4. Record water level.
5. Subtract difference in water level.

Front 12

Relationship Between ml and cm3

Back 12

A mililiter is equal to the volume of a cube that measures 1 cm on each side. Since the volumn of a cube is equal to the length times the width times the height, the volume of a cube that measures 1 cm on each side is equal to 1 cm3.

Front 13

Density

Back 13

mass (g)/ volume (ml or cm3)

Front 14

Density of Water

Back 14

1 g/ml or g/cm3. Objects with a density greater than 1 will sink and less than 1 will float.

Front 15

Atoms

Back 15

The smallest units of an element which retain the properties of that element.

Front 16

Elements Abundant in Living Things

Back 16

(C) carbon, (H) hydrogen, (N) nitrogen, (O) oxygen, (P) phosphorus, and (S) sulfur

Front 17

Molecules

Back 17

Built of atoms bonded together.

Front 18

Organelles

Back 18

Sub-units of cells composed of molecules. They are compartments for specialized functions, often surrounded by a membrane.

Front 19

Nucleus

Back 19

The chromosome containing organelle of a eukaryotic cell.

Front 20

Chloroplast

Back 20

An organelle found in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water.

Front 21

Cells

Back 21

The fundamental units of life. The smallest unit that can have all of the charateristics of living things.

Front 22

Tissues

Back 22

Groups of similar cells.

Front 23

Parenchyma Tissue

Back 23

A relatively unspecific plant tissue type that carries out most of the metabolism, synthesizes and stores organic products, and develops into a more differentiated cell type. Example: The thin-walled cells of the dicot root function in the storage of starch.

Front 24

Vascular Tissue

Back 24

Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body. Example: The inner portion of the dicot root contains it.

Front 25

Xylem

Back 25

Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant.

Front 26

Phloem

Back 26

Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant.

Front 27

Organs

Back 27

Made up of diverse tissue types.

Front 28

Organ Systems

Back 28

Made up of multiple organs. Example: the plant root and shoot

Front 29

Organisms

Back 29

Individual living things.

Front 30

Unicellular Organisms

Back 30

Consist of one cell. Example: bacteria and amoeba

Front 31

Multicellular Organisms

Back 31

Have many cells, but can also have tissues, organs, and organ systems. Example: Plant with intact root and shoot systems, a grasshopper, and a pig.

Front 32

Populations

Back 32

Consist of localized groups of organisms belonging to one species. Example: All of the humans in Central Florida.

Front 33

Communities

Back 33

Made up of all the living things, that is alll the populations, in a local area. Example: All the organisms on Hood Island of the Galapagos Archipelago.

Front 34

Ecosystems

Back 34

Consist of the community (the living things or biotic components), plus the non-living (or abiotic) components of an area. Abiotic components include soil, water and climate. Example: Florida's Everglades is a marsh, a treeless wetland.

Front 35

Biosphere

Back 35

The largest or highest level of biological organization. It is the part of the Earth that supports living things, from deep in the ocean to the highest mountaintop. It includes all of the Earth's ecosystems, the realm of life.
