Standard 6-2.1:
1. What 4 things do all living things share? Grow/develop, obtain resources, respond to stimuli, reproduce
2. Autotrophs provide their own food for energy through photosynthesis?
3. Heterotrophs must find an external source for food?
4. This is any change in an organism’s surroundings that will cause the organism to react. stimulus
5. A reaction to a stimulus is called a? response
Standard 6-2.2:
6. The 7 levels of classification from biggest to smallest are? Kingdom, phylum, class, order, family, genus,
species
7.
The genus is the first word in an organism’s scientific name.
8.
The species is the second word in an organism’s scientific name.
9. Organisms from the same species are similar and can breed together to produce a young of the same kind.
Standard 6-2.3:
10. These plants have true roots, stems, and leaves. vascular
11. These plants do not have a well-developed system for transporting water and food and get their resources
from the environment. Examples are liverworts, mosses, and hornworts. nonvascular
12. The ________ in the stem transports water from the roots to the leaves. xylem
13. The ________ in the stem transport food made in the leaves to the plant. phloem
14. What are the 2 major groups of seed-producing plants called? Flowering and cone-bearing
15. This is the beginnings of roots, stems, and leaves and is found in the seed surrounded by the seed coat.
embryo
16. Where do flowering plants grow their seeds? What can the seed become? In ovary, fruit
17. Conifers produce ___________ in cones, not flowers. seeds
18. A seed with one food storage area, petals in 3’s or multiples of 3’s, and long and slender leaves are called?
monocot
19. A seed with two food storage areas, petals in 4’s or 5’s, and wide leaves with branching veins are called?
Dicot
Standard 6-2.4:
20. Name 3 structures for defense plants have. Poisons, thorns, thigmotropism
21. The leaves are the main structure that functions as the food producer for plants. The three things that leaves
do are respiration, transpiration, and photosynthesis.
22. What is the function of a stem? Hold the plant up to light
23. These help anchor the plant in the ground, absorb water/nutrients from the soil and store extra food. roots
24. These help to increase the root’s surface area. Root hairs
25. This type of root has several main roots that branch off to form a mass. Fibrous root
26. This type of root has one large main root with smaller roots branching off. taproot
27. These flower parts are colorful or have a scent to attract insects and other animals. petals
28. The male part of a flower that has an anther on a filament is called the? stamen
29. The male part of a flower that makes pollen is called the? anther
30. The female part of a flower is called the? pistil
31. This is the part of the flower that contains the ovules where the egg cells are produced. ovary
32. The sticky top of the flower where pollen grains land is called the? stigma
33. The female stalk down which the pollen tube grows after pollination is called the? Style
Standard 6-2.5:
34. What is germination? Seat coat breaks open and roots start to grow
35. This process is when pollen transfers from the stamen to the pistil. fertilization
36. This process happens when pollen enters the ovule, which is located in the ovary of a flower. fertilization
37. What does the ovule develop into once it is fertilized? seed
38. What does the seed develop into? Fruit

42. Process of growing new plants from plant parts is known as asexual.
43. These are all types of underground stems (onions and potatoes). Tubers/bulbs
44. These are all types of stems that run along the ground (ivy and strawberries). runners
45. Roots may form when a piece of cut stem is planted through this. Sugar cane and pineapple are examples of
plants grown from this. Stem cuttings

47. African violets can produce plants from leaves.
Standard 6-2.7:
