Study Guide Review- Unit 7 Test

Question Answer
Describe the two part life cycle of a plant. 1) sporophyte- a stage of plants that produces spores
2) gametophyte- a stage of plants that produces sex cells
What are some examples of nonvascular plants? 1) mosses
2) liverworts
How do nonvascular plants obtain water? – through osmosis and diffusion
Give examples of seedless, vascular plants. – ferns, horsetails and club mosses
Give examples of angiosperms. – daisy, rose, tulip
Give examples of gymnosperms. – conifers
Name the structures of a root. 1) root cap
2) root hairs
3) epidermis
4) xylem
5) phloem
What is the function of the root cap? – it protects the roots and allows it to slide through the soil
What is the function of the root hairs? – it increases the surface area for more water and nutrient absorption
What is the function of the epidermis in a root? – it is the outer layer of the root
What is the function of the xylem in the root? – it carries water
What is the function of the phloem in the root? – it carries sugar
Name the structures of a leaf. 1) the epidermis
2) the palisade layer
3) the spongy layer
4) the stomata
5) the guard cells
What is the function of the epidermis in a leaf? – it is the outer layer of the leaf
What is the function of the palisade layer in the leaf? – it has the chloroplasts
– it is where photosynthesis occurs
What is the function of the spongy layer in the leaf? – it is where gasses move around in the leaf
What is the function of the stomata in the leaf? – carbon dioxide, oxygen and water enter and exit through these holes
What is the function of the guard cells in a leaf? – they regulate the opening and closing of the stomata in a leaf
Name the 2 structures of a stem. 1) xylem
2) phloem
What is the function of the xylem in a stem? – it carries water in the stem
What is the function of the phloem in the stem? – it carries sugar in the stem
Through which structure does carbon dioxide enter a leaf? – the stomata
Describe the entire process of pollination and fertilization. (part 1) Pollen is created in the male reproductive structure-the stamen. The anther is on top held up by the filament. Pollen is
transferred to the female reproductive structure-the pistil. It lands on the top-the stigma.Travels down the style,into the ovary
Continue with describing the process of fertilization. (part 2) The sperm-inside the pollen fertilizes an egg-inside the ovule. The fertilized egg turns into a seed, and the ovary turns into a fruit.
What are the 3 parts of a seed? 1) the seed coat
2) the cotyledon
3) a young plant
What does a seed need to germinate? -water
Compare and contrast dicots and monocots. Dicots- they have two cotyledons, they have branching veins in leaves and the flower parts in 4's or 5's
Monocots- they have one cotyledon, they have parallel veins in the leaves, the flower parts in 3's
Compare and contrast xylem and phloem. 1) They are both types of vascular tissue found in vascular plants
2) Xylem- located in the middle and it transports water
3) Phloem- located on the outside and it transports sugar
What is the difference between evergreen and deciduous trees? Evergreens- lose leaves (needles) little by little year round.
Deciduous- trees that lose leaves all at once, seasonally
What is the difference between angiosperms and gymnosperms? Angiosperms- vascular plants with seeds and flowers
Gymnosperms- vascular plants with seeds, without flowers, and they have cones
What is a tropism? -a plant's response to an environmental stimulus (light and gravity)
List 3 types of vegetative propagation. 1) runners
2) cutting
3) budding
What does the cotyledon store? -it stores food for the young plant (starch)
