Term | Definition |
Ovule | A plant structure in seed plants that produces the female gametophyte; contains an egg cell |
Stigma | the sticky tip of a pistil |
Anther | pollen is produced in the anther, at the top of the stalklike filament |
Stamen | the male reproductive part of a flower |
Petal | A colorful leaf like structure of some flowers |
Ovary | a flower structure that encloses and protects ovules and seeds as they develop |
Style | A slender tube connects the the stigma to a hollow structure at the base of the flower |
filament | the thin stalk of the stamen |
pollination | the transfer of pollen from male reproductive structures to female reproductive structures in plants |
fertilization | the joining of a sperm cell and an egg cell |
chlorophyll | a green pigment found in the chloroplasts of plants, algae, and some bacteria |
embryo | the young organism that develops from a zygote |
Seed coat | the outer covering of a seed |
cotyledon | a seed leaf; sometimes stores food |
monocot | an angiosperm that has only one seed leaf |
Dicot | an angiosperm that has two seed leaves |
vascular tissue | the internal transporting tissue in some plants that is made up of tube like structures that help water, minerals and food move |
xylem | the vascular tissue through which water and nutrients move in some plants |
Phloem | the vascular tissue through which food moves in some plants |
tropism | the growth response of a plant toward or away from a stimulus |
Pistil | the female reproductive parts of a flower |
Characteristics of a seed plant | vascular tissue and they use pollen and seeds to reproduce |
functions of plant's flowers and roots | roots have three main functions:
1)Anchor a plant in the ground
2)Absorb water and minerals
3)store food |
How seeds are dispersed | by animals, wind and/or water |
What is required for photosynthesis and what is produced? | sunlight, water and CO2. Oxygen, sugar, and plant food are produced. |
What role chlorophyll plays in photosynthesis | |
How plants reproduce through pollination and fertilization | |
the differences between monocots and dicots (table from notes) | Monocots:
1)seed has 1 food storage area
2)straight leaf
3)petals in multiples of 3
Dicots:
1) 2 food storage areas
2) heart shaped leaf
3)petals in multiples of 4 or 5 |
Thigmotropism | a plants response to touch |
Phototropism | a plants response to light |
Gravitropism | a plants response to gravity |
Dormancy | a period when an organisms growth or activity stops |
photosynthesis | the process by which plants use the suns energy to make their own food |
