Cell is a basic unit of all living things Life processes

CHAPTER 1.

1. 
   A cell is a basic unit of all living things
   
2. 
   Life processes are the activities that keep living things alive
   
3. 
   Green plants need three things to make foods. ( water, carbon dioxide and light
   

energy )

4. 
   A root hair is part of a single cell that grows from a root into the soil
   
5. 
   Most leaves contain small thin tubes called veinz ( looks like tubes)
   
6. 
   The openings in the leaf called stomata
   
7. 
   The processes by which green plants make food is called photosynthesis
   
8. 
   A chloroplast is a small green body in plant cell
   
9. 
   Chlorophyll is the material that is needed by plant to make food
   
10. 
    Respiration is the process by which living things use oxygen to release energy
    

in food

11. 
    Reproduction is the process by which living things produce new living things of
    

the same kind

12. 
    The petals are the leaflike outer parts of a flower
    
13. 
    The stamen is the male reproductive part of a flower
    
14. 
    The pistil is the female reproductive part
    
15. 
    A pollen grain is a tiny body that contains the male reproductive cell
    
16. 
    The ovary is the part of the plant that contains ovules.
    
17. 
    An ovule is a small round body that contains the female reproductive cells.
    
18. 
    Pollination is the process by which pollen grains move from the stamen to
    

the pistil

19. 
    The joining of male and female reproductive cells is calleds fertilization
    
20. 
    The fertilized ovule becomes a seed containing a tiny young plant and stored
    

food. A tiny young plant is called an embryo

21. 
    The growth of a plant embryo from a seed is called germination
    

CHAPTER 2

1. 
   To classify is to arrange in groups by features that are like
   
2. 
   The backbone is made up of many small bones called vertebrae
   
3. 
   An animal with a backbone is called a vertebrate
   
4. 
   An animal without backbone called an invertebrate
   
5. 
   A sponge is an invertebrate that has many cells
   
6. 
   A tentacle is a long, armlike part
   
7. 
   A stinging cell is a special structure used to help capture food
   
8. 
   A common flatworm found in fresh water is the planarian
   
9. 
   An organ is a body part that does a certain job
   
10. 
    Planarians can regenerate, or regrow, body parts that are missing
    
11. 
    A parasite is an animal or plant that depends on and harms another animal or
    

plant. The animal or plant on which a parasite depends is the host

12. 
    A roundworm is a worm that has a long tube-shaped body with a digestive
    

system

13. 
    A segmented worm is a worm whose body is divided into segments, or sections
    
14. 
    A bristle is a stiff, strong hair used for moving
    
15. 
    An echinoderm is a spiny-skinned invertebrate that lives in the ocean
    
16. 
    A tube foot is a hollow structure with a sucker at the end
    
17. 
    A mollusk is an invertebrate with a soft body
    
18. 
    An arthropod is an invertebrate that has asegmented body and joined legs
    
19. 
    Outer covering of all arthropods is called the exoskeleton
