11. The two stages or generations in every plant's life cycle are the __________________________
stage and __________________________________________ stage. (2 pts)
12. List the THREE characteristics that ALL members of the Kingdom Plantae share. These can NOT
be the same six characteristics that all living things (organisms) share. (3 pts)
__________________________________________________________
__________________________________________________________
13. Which kind of vascular, seedless plant did American colonists use to scrub their pots and pans
because they contain silica? _____________________________________
14. The costly method of growing plants in a SOLUTION containing nutrients instead of soil - often
used in places where there is not good soil - is called __________________________________ .
15. Structures that contain a young plant and stored food inside a protective covering are called
______________________________ .
16. The early growth stage of the plant embryo that begins when the seed absorbs water from the
environment is called _____________________________________________ .
17. What is the protective round structure made up of dead cells that covers the tip of a root called
(sort of like a steel-toed boot for the root)? ___________________________________
18. Name and draw the two types of root systems that seed plants may have and give at least one
example of each type. (6 pts)
19. In the woody stem, what is the layer of cells inside the phloem called which can divide in order
to produce both new xylem and phloem? ____________________________________
20. Name the two types of vascular tissue in plants AND their function.
(4 pts)
________________________________________________________________________________
________________________________________________________________________________
21. Tiny structures growing out of the roots which increase the surface area of the root and which
greatly increase the water and nutrients that can be absorbed: __________________________
22. ALL gymnosperms are seed plants that produce what kind of seeds? _______________________
They are called this because these seeds are not inside a _________________________ . (2 pts)
23. There are four types of gymnosperms. Match each group and description. (4 pts)
_____ Conifers
A. Most people will not see these because they grow
only in hot, dry deserts or tropical rain forests
_____ Gingko
B. These look like palm trees with cones – mainly grow in
tropical or subtropical regions, e.g. in Mexico
_____ Gnetophytes
C. Only one species of these still survives, probably
because the Chinese and Japanese tended them
_____ Cycads
D. The largest and most diverse group of gymnosperms
which are typically evergreen trees
24. The reproductive structures in gymnosperms are the ________________ .
25. What are the tiny grains called which are produced by male cones, and also the anthers of
stamen in flowers, and which contain sperm cells and produce hollow tubes for the sperm to
travel through to get to the egg?
________________________________
26. The process where pollen from the male reproductive structure is transferred to a female
reproductive structure is called ______________________________________ .
27. (2 pts) The two characteristics of angiosperms (besides they are vascular and seed plants) is
that they produce _____________________ and _________________________.
28. The leaflike structures that enclose the flower when it is still a bud and has not opened up yet
into a flower are called ______________ . (These help hold and protect the developing flower.)
29. What is the reproductive structure in angiosperms? ___________________________
30. What is the sugary liquid in a flower called that attracts birds, bats, and insects so that they
knock off the pollen while trying to get to it? ___________________
31. What is the (total) male part of the flower called? __________________________
32. What is the (total) female part of the flower called? ________________________
33. A plant’s growth response to certain stimuli, such as light, gravity, or touch, is called a
_____________________________________ .
34. Chemicals that the plant produces which control its growth and development (and which
animals, including people, produce also) are called ____________________________________ .
35. List four ways that plants benefit the world - it can be us and/or other species: (4 pts)
________________________________________________________________________________
________________________________________________________________________________
True/False
36. ______ Since the more times the pollen is shaken loose, the better the chances for pollination
to occur, the shape, color, patterns, and scent of the flower petals are generally
designed to attract a wide variety of many different pollinators.
37. ______ The adaptation that prevents new plants from having to compete with the parent plant
for the same limited resources of soil, water, nutrients, space, and sunlight is referred
to as genetic engineering.
38. ______ Vascular tissue, seed dispersal methods, the variety of ways pollination can occur (in
different plants), and the ability of pollen to create a pollen tube for the sperm to travel
through to fertilize the egg are all reasons that seed plants have survived and thrived
basically everywhere on the planet.
Name the parts of the flower below. Write the name next to the description:
39. Part of the flower designed to attract specific pollinators
40. Structure that produces pollen
41. Structure that supports # 40
42. Structure that eventually becomes the fruit, where the ovules and egg cells are
43. Leaf-like structure (sometimes) that encases and protects the flower bud
44. The stalk-like structure on the female part of the flower
45. The sticky end of the female part of the flower
