Vascular & Nonvascular plants
VASCULAR PLANTS
• Have true conducting tissues, leaves, stems, and roots.
• Majority of plants are vascular
NONVASCULAR PLANTS
• Lack conducted tissues, leaves, stems and roots.
• Require water for fertilization and must grow in seasonally moist habitats.
Vascular & Nonvascular plants
• Vascular plants- a plant that has a well developed system of conducting tissues to transport water, sugars and mineral salts which is carried through a tube.
• Nonvascular plants- any various plant that lacks tissue and requires water for fertilization and grow in seasonally moist habitats.
Angiosperms & Gymnosperms
• Angiosperms• Flowers• Pods & fruit hold
seeds• Leaves• Branches• (produces fruit)• Flowering trees
• Gymnosperms• Cones• Needles• Branches• (is not protected by
fruit)• Coniferous trees• Naked seeds
Reproduction of angiosperms & gymnosperms
• Gymnosperms have cones. • The male cones produce pollen.• The female cone produces the seed.• The pollen is blown by the wind.• Angiosperms have flowers. • The pistil is the female reproductive structure.• The stamen( male part) produces the pollen. • Insects carry pollen from one flower to the other
Angiosperms• These flowering plants are divided into two
major types.
• Monocots & Dicots
• Monocots- grass like angiosperms, have only a single first leaf.
• Dicots- include all of the non-monocot angiosperms, have paired first leaves.
Questions
Which process is prevented from occurring when the
stamens are removed from an angiosperm?
ANSWER
Self-pollination
Which is the transfer of pollen from an anther to a stigma of the
same flower.
???
A. Plant 1- wind- fruit
B. Plant 2- wind- cones
C. Plant 3- insects- fruit
D. Plant 4- insects- cones
ANSWER
Vascular plants have the tube that carries water up the tree or plant and
nonvascular plants don't.
Monocots have a single first leaf and dicots have 2 first leaves.
Mono – means one or single
Di – means 2 like 2 dice
ANSWER
