Chapter 4: Plants and Photosynthesis

VOCABULARY FOR THE WEEK OF March 19th-23rd

1.  photosynthesis: the process that plants and some organisms use to make 
sugar for food.

2.  xylem:  tiny tubes that carry water from the roots to other parts of the 
plant.

3.  phloem: tubes that carry sugar to the other parts of the plant.

4.  sugar: glucose, the food that plants make.

5.  roots: they anchor the plant in place, store food, and their major job is 
to absorb water.

6.  chlorophyll: a green substance that provides plants their green color.

7.  stomata: the "lungs" of plants, small tiny cells underneath the leaves.

8.  chloroplasts: the green part of a plant cell that uses the energy in 
sunlight to turn water and carbon dioxide into oxygen and sugar.

9.  cell respiration: the process of releasing energy from nutrients.

10.  transpiration: the release of water vapor into the air from a plant's 
leaves.

11.  pollen: a powdery material in flowers that contain sperm cells.

12.  pollination: the transfer of pollen from the stamens to the pistil of a 
flower.

13.  spore: a seedlike structure that produces a new plant.

14.  embryo: a plant or animal in the earliest stage of development.

15.  tropism: a plant's response to a stimulus such as light, water, or 
gravity.

Use your science textbook to answer the following questions in YOUR SCIENCE 
COMPOSITION NOTEBOOK to review for the Chapter Test)

1.)  How are plant spores different from seeds?

2.)  What functions does the xylem tissues perform?

3.)  Most water enters a plant through which of the following structures: 
taproots, root hairs, root bundles, or fibrous roots.

4.)  Which type of plant has the least amount of xylem tissue?

5.)  How would a leaf best be classified?

6.)  Which part of a leaf protects the plant from the outside?

7.)  Leaves have many tiny openings on the bottom.  What is the purpose of 
these openings?

8.)  Look at the following diagram about photosynthesis. Which part is 
missing?

CARDON DIOXIDE  +    WATER   +   SUNLIGHT (ENERGY)  =   OXYGEN  +     ?

9.)  Which type of seed has two areas of stored food and produces a plant 
with branched out veins on the leaves?

10.) Which of the following is true of asexual reproduction?
      a.)  type of DNA only
      b.)  environment only
      c.)  environment and DNA
      d.)  environment or DNA, depending on the plant

11.) Practice drawing the Photosynthesis Tree Diagram and include all labels 
(you will be expected to draw for the test).
