2 What is a Plant?

3 Multicellular, eukaryotic, autotroph that uses chlororplast

4 Most of the photosynthetic activity in plants takes place in _____ of a leaf.

5 Mesophyll

6 Oxygen & carbon diffuse in and out of pores called _____

7 Stomata (stomates)

8 Explain the difference between a gametophyte & a sporophyte

9 Gametophyte – haploid half a set of chromosomes Sporophyte- diploid full set

10 Without gas exchange plants could not…

11 Make food

12 What does a plant need to survive?

13 Sunlight, water & nutrients, gas exchange

14 Explain the force that allows water to move up a plant. What is it called when water leaves the leaf?

15 Cohesion & Adhesion Transpiration

16 The 2 types of vascular tissue in a plant are __________ which moves____________ &______________ which moves ______________.

17 Xylem – Water Phloem – Sugar (glucose)

18 Plants evolved many things to deal with water shortage including

19 Cuticle, smaller leaves, (close stomata during the day)C4, increase of ABA

20 Explain phototropism. What hormone allows for this?

21 Plants growth towards like. Auxin (not evenly distributed)

22 What is true about seeds?

23 Not found in all plants, they are found in gymnosperms and angiosperms, have nutrients for embryo

24 Where is new plant growth occurring? What process is happening exactly?

25 Meristems; mitosis

26 Identify Structure B. in a Leaf Function?

27 Stomata; gas exchange

28 Identify Structure C What’s the function? C

29 Spongy mesophyll; space for gases needed for photosynthesis

30 Identify the Structures D. What’s there function? Tissue Type?

31 Vascular tissue; movement of water & sugar

32 Explain the difference between gymnosperms and angiosperms

33 Gymno-naked seeds, cones, single fertilization Angio- covered seeds, fruits/flowers, double fertilization

34 What is created by dermal tissue? What are the benefits of these tissues?

35 Root hairs and trichomes on a leaf, increase surface area for water absorption and photosynthesis

36 If one very ripe fruit is in your basket what hormone is bring released? What hormone is turned off to allow for a plant to start doing secondary growth (grow more bushy)?

37 Ethylene; Auxin

38 After fertilization ovary becomes the _________ and the ovule becomes the __________

39 Ovary- fruit Ovule - seed

40 What kind of animal would be the best to have the widest seed dispersal? Seeds for animals are usually kept in ______.

41 Bird or Bat since they fly long distances. Fleshy sweet fruits

42 What is germination? What does a seed wait for to start germinating? What hormone is washed away for this to begin?

43 When a seed starts to grow, water/fire/temperature, Abscisic Acid (ABA)

44 The female reproductive parts are all called_______. & Consist of….

45 Pistil ; stigma, style, ovary, ovules

46 Identify structure C. What does it produce? What is inside these cells?

47 Anther; make pollen; 3 cells 2 sperm and one cell to make the pollen tube.

48 Identify Structure A. Function?

49 Stigma; Gets pollen

50 Explain what is happening here.

51 The pollen grain or microsporocyte lands on the stigma and grows a pollen tube that heads towards the microphyle. The pollen releases 2 sperm cells into the megasporagium one fertilizes the polar nuclei forming endosperm the other fertilizes the egg and becomes the seed
