2. All About Plants Plants are multicellular eukaryotes that have cell walls made of cellulose.
Plants are in the Kingdom Plantae
Plants are autotrophs ( they make their own food)
3. Roots- help to anchor the plant in the soil so it doesn’t fall over
Stems- support the plant; act as the plants pluming system by conducting water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts
Leaves- designed to capture sunlight which they use to make food through photosynthesis
Photosynthesis- they use the energy from sunlight to produce glucose Flowers- the reproductive part of
most plants
Seeds- an embryo of a plant that is encased in a protective covering and surrounded by food supply
4. Vascular & Nonvascular Plants Vascular refers to the tubes or vessels that water travels through from the roots to the stems & leaves.
Nonvascular plants do NOT have these tubes. Most of the plants in this group are small, low to the ground.
Vascular plants do have these tubes to carry the water & nutrients & can grow very tall
5. Vascular & Nonvascular Plant Comparison
6. Vascular Plants are divided into 2 Groups by the way they reproduce Gymnosperms ( means “Naked Seeds”) are the trees that have cones.Their seeds are not covered with a fruit so we say they
are naked.
Angiosperms are trees & plants that have flowers & fruits.
7. Gymnosperm & Angiosperm Comparison
8. Parts of a Flower Stamen- (it has the word Men in the word) the male part of the
flower and they produce a sticky powder pollen
Pistil- the female part of the body;
Stigma- the top part of the pistil which is often sticky
Ovule- the base of the pistil where seeds are made
Petals – attract the insects
with color & scent but
they do NOT have a
reproductive function
9. Pollination Angiosperms are pollinated by insects The flowers are often bright colored and have a strong smell to attract the pollinators
Gymnosperms are pollinated by wind . The wind picks up pollen from one pine tree and carries it to another.
10. Monocots and Dicots Two classes within the angiosperms: the monocots, and dicots.
Monocots and dicots are named for the number of seed leaves, or cotyledons, in the plant embryo ( in other words, how many leaves come out of the ground when the plant first sprouts)
Monocots have one seed leaf
Dicots have two seed leaves
11. Cotyledons Cotyledon- the first leaf or the first pair of leaves produced by the embryo of a seed plant
12. Monocot & Dicot Comparison
13. Venation Patterns
15. Question 1 Which student has correctly classified each plant?
16. Answer… D.STUDENT 4
17. Question 2 A class observes an unknown plant and discovers that the plant’s seeds have only one cotyledon. When the class examines the leaves and the stem, what will they MOST LIKELY find?
A parallel veins and a ring of vascular bundles
B parallel veins and scattered vascular bundles
C a netted arrangement of veins and a ring of vascular bundles
D a netted arrangement of veins and scattered vascular bundles
18. Answer… B. Parallel veins and scattered vascular bundles
19. Question 3 Why are nonvascular plants typically smaller and shorter than vascular plants?
A Nonvascular plants use mitosis to produce cells.
B Nonvascular plants use photosynthesis to obtain energy.
C Nonvascular plants lack tubes to transport materials.
D Nonvascular plants lack deep fibrous roots to obtain water.
20. Answer… C. Nonvascular plants lack tubes to transport materials
21. Question 4 Study the table below. Which statement is correct?
22. Answer… C. Plant 1 is a monocot, and plant 2 is a dicot
23. Question 5 Study the leaf below.
A plant with the leaf- venation pattern shown would be classified a
24. Answer… DICOT
Dicots have netted venation
25. Question 7 What kingdom are plants in?
The flower kingdom
Kingdom Plantae
Kingdom Fungi
Kingdom Animalia
26. Answer B. Kingdom Plantae
27. Question 9 What is the first leaf or the first pair of leaves produced by the embryo or seed plant?
Dicot
Gametophyte
Monocot
Cotyledon
28. Answer D. cotyledon
29. Question 10 Which has a single cotyledon?
Sporophyte
Monocots
Fuit
dicots
30. Answer B. Monocots
Mono means single or one
31. Question 12 What are plants considered?
Autotrophs
Monotrophs
Hetertrophs
green
32. Answer A. autotrophs
33. Question 13 Do plants have eukaryotic or prokaryotic cells?
Hint: Prokaryotic cells are very primitive & do not have true organelles.
Eukarytotic cells are “true cells”
34. Answer Eukaryotes
Only bacteria are Prokaryotic cells. All others are made up of True cells
