Living Organisms Review

Chapter 1

1. The idea that life could spring from nonliving matter is called….

• B) Spontaneous generation

• P. 10 1 st paragraph

2. The scientific study of how living things are classified is called…

• C) Taxonomy

• Page 17 3 rd paragraph

3. A genus is divided into…

• A) Species

• Page 21

4. Which organisms have cells without nuclei?

• B) Archaea

• page 27-29

• 6. Bacteria are unicellular organisms.

– true

• 7. Heterotrophs can make their own food.

– False: autotrophs (p. 12)

• 8. Linnaeus devised a system of naming organisms called binomial nomenclature.

– True (p. 19)

• 9. The gray wolf, Canis lupis, and the red wolf,

Canis rufus, belong to the same species.

– False: genus (p. 18)

• 10.The cells of a prokaryote lack a nucleus.

– True (p. 27)

11. Your friend thinks that plants are not alive because they do not move. How would you respond to your friend?

• Students might point out that plants will bend toward sunlight and that plants grow, develop, and reproduce.

• P. 7-9

15. What is the major difference between fungi and plants?

• Fungi are heterotrophs; plants are autotrophs

• P. 28

17. How do you know that a robot is not alive?

• Although all robots use energy and some respond to their environments, they do not use energy to grow and develop. Living things are made of cells and are able to reproduce themselves.

• P. 7-9

20. How many domains do the following organisms represent?

Kingdoms?

• One Domain (Eukarya)

• 2 Kingdoms (animal and plant)

• P. 27-29

22-25 are about the plants in light and darkness

22. Is this a controlled experiment?

If so, identify the manipulated variable. If not, why not?

• Yes, the light is a manipulated variable.

23. What hypothesis might this experiment be testing?

• Same hypothesis: If the amount of light is decreased, then the plant will not grow_________.

24. Based on what you know about plants, predict how each plant will change in two weeks.

25. Design a a controlled experiment to determine whether the amount of water that a plant receives affects its growth.

Standardized Test Prep

• 1. D p. 7

• 2. J p. 27-29

• 3. B p. 19 will help

• 4. H p. 18-19 will help

• 5. C p. 11 will help

• 6. Cellular Organization, contain similar chemicals, use energy, respond to their surroundings, grow and develop, and reproduce. (p. 7-9 list)

Living Organisms Review

Reproduction

Reproduction

• Sexual

– Most eukaryotic, mulitcellular organisms

– Takes longer due to complicated process

– Most plants and animals

– 2 parents required

• Genetic diversity

• Allows adaptations to changed in environment

• Get genetic info from both parents

• Asexual

– All prokaryotic organisms

– Mostly unicellular organisms

• Not common in multicellular organisms

– Only 1 parent required

• Daughter cells identical to parent cells

Chapter 4

Plants & Photosyntheiss

1. Mosses and trees are both…

• D) plants

• P. 108-110

2. The structures in plant cells in which food is made are called…

• B) chloroplast

• P. 117

3. When visible light strikes a green leaf, most of the green light is…

• A) Reflected

• P. 115

8. Leaves are green due to accessory pigments.

• False: chlorophyll

• P. 116

9. Sugars and oxygen are the products of fertilization.

• False: photosynthesis

• P. 119

10. Mosses are vascular plants.

• False: nonvascular

• P. 108

14. What role does chlorophyll play in the photosynthesis process?

• Chlorophyll absorbs most of the red and blue colors of light so the energy in these colors can be used to power photosynthesis.

• P. 115-116

16. In what two ways is vascular tissue important to a fern plant?

• Vascular tissue enables the fern to efficiently transport water and food to all its cells and support the plant so it can grow large.

• Discussion & p. 108-109

21. A friend tells you that he has seen moss plants that are about 2 meters tall. Is your friend correct?

Explain.

• No, the friend is most likely mistaken.

Mosses are nonvascular, and cannot grow more than a few centimeters tall due to the lack of vascular tissue to transport food and water.

What is the chemical equation for photosynthesis?

light energy

6CO

+ 6H

From Discussions in Class

How is photosynthesis like baking a cake?

• Plants need ingredients of Carbon Dioxide and Water like the eggs, flour and water to make the cake. To make the cake, you need to bake it, which is heat energy, like plants need light energy from the sun to actually make the food. The plants actually make glucose (aka sugar) and oxygen .
