Types of seedless plants
4
Vascular & Non- vascular
5
All Non-vascular plants have two parts :
6
#1: They all have leafy stalks #2: RHIZOIDS. holds the plants in place and help get food. Above the ground
7
All vascular plants with out seeds have two parts :
8
#1: They all have leafy stalks #2: RHIZOME (different from the rhizoid). These are stems into the ground
10
3 Characteristics of a seeded plant :
11
#1 : Has seeds : protects & feeds sporophyte
13
# 2 : Gametophyte lives in the sporophyte
14
REMINDER : separate gametophyte & sporophyte in seedless
15
In a seed
16
#3 seedless plants need water for reproduction & seeded do not.
17
Seeds have three main parts.
18
#1 Gametophyte (the baby plant)
19
#2 Seed coat
20
#3 Cotyledon (food storage)
21
Two types of Seeded plants :
22
Non-flowers (Gymnosperms) & Flowers (Angiosperms)
23
Gymnosperms (non-flowers are) are :
24
Pine tree
25
Cycads
26
Ginkos
27
4 stages of the life cycle Gymnosperms (plants have both male & female parts)
28
#1) the male part releases pollen which the wind carries to another tree.
29
#2) The pollen fertilizes the egg and makes the seed.
30
#3) The seed flies away or falls on the ground.
31
#4) The seed grows into a new plant and it starts over.
33
Angiosperms (flowered plants) are :
34
Rose Bush
35
Apple tree
36
Peach Tree
37
Only one difference in flowering plants life cycle. (stage One)
38
#1) the male part releases pollen which insects carry to another plant.
39
#2) The pollen fertilizes the egg and makes the seed.
40
#3) The seed flies away or falls on the ground.
41
#4) The seed grows into a new plant and it starts over.
42
Group work : In pairs you will create a poster showing a flowering plant’s life cycle on Thursday.
43
Homework: in complete sentences. Homework: Homework: page 385 #2.a.b. and #3.a.b.c. in complete sentences.
