Describe kingdom plantae (characteristics of plants) |
*eukaryotic *Multicellular *Autotrophic *Made up of specialized tissues and organs *Able to absorb nutrients through roots (or rhizoids)
|
|
|
What is haploid? |
(n) Gametophyte |
|
|
What is diploid? |
Sporophyte (2n) |
|
|
Why did vascular plants need to live in a water packed environment? |
Sperm had to swim from male to female reproductive organs for fertilization. |
|
|
What is the function of a plant ovule? |
The ovule is a female reproductive structure in seed plants that contains a female Gametophyte. The Gametophyte produces an egg cell. After the egg is fertilized by the sperm, the ovule develops into a seed. |
|
|
Plants need oxygen because... |
They carry out cellular respiration just like all other aerobic organisms |
|
|
Vegetative reproduction is a |
Type of asexual reproduction |
|
|
Define sporophyte |
The diploid generation produced by sexual reproduction |
|
|
Define flower |
A reproductive structure in angiosperms; may contain pollen and egg cells |
|
|
Define gymnosperm |
Modern seed plants that produce seeds in cones |
|
|
What's an ovary? |
A reproductive structure (present in flowers) that contains the female Gametophyte |
|
|
What is the function of both the cuticle and the lignin? |
Waterproof and strength-providing molecule in plant cell walls |
|
|
What is alternation of generation? |
A type of life cycle during which plants alternate between haploid and diploid generations |
|
|
Vegetative reproduction |
A form of of asexual reproduction from stem,roots,or leaves |
|
|
Define rhizoid |
A structure for water absorption in nonvascular plants |
|
|
Gametophyte |
Haploid individuals produced by asexual reproduction |
|
|
Cone |
Seed container in gymnosperms |
|
|
What advantages do stems give vascular plants? |
*Stem is made of vascular tissue and lignin *Lignins allow stems to remain stiff and grow high above the ground to more light and air *Allows plants to remain supplied with water so they don't dry out |
|
|
Which seed structure provides the main source of food for the embryo? |
Hypocotyl |
|
|
Petal |
Part of a flower that is often colorful so pollinators will be attracted |
|
|
Tracheophyte |
Seed plants |
|
|
Pistil |
Female reproductive structure containing the stigma,style, and ovary |
|
|
Endosperm |
The area in many seeds where food is stored |
|
|
Spermatophyte |
Vascular plants |
|
|
Sepal |
Structure protecting the immature flower bud |
|
|
Bryophyte |
Nonvascular plants |
|
|
Stamen |
Pollen producing structure |
|
|
Seed coat |
A structure protecting the embryo |
|
|
Xylem |
Vascular tissue that transports water and minerals |
|
|
Phloem |
Vascular tissue that transports sugars |
|
|
The mature sporophyte of a fern |
Produces haploid spores by mitosis |
|
|
Pollen contains |
Male gametes |
|
|
What are the five kingdoms of life? |
Anamalia- multicellular eukaryotic heterotrophes with no cell walls Plants- multicellular eukaryotic autotrophes with cell walls made of cellulose Fungi- multicellular eukaryotic heterotrophes with cell walls made of chitin Protista- unicellular eukaryotic organisms, some are autotrophes and some are heterotrophes. Monera- unicellular prokaryotic organisms, some are heterotrophes some are autotrophes |
